Folks,

We hope all of your are doing well 😀 It has come to our attention that some of you are interested to know more about the upgrade service that we offer. That said, I'll do my best to fill you in below, but if you still have any questions please don't hesitate to post back here and we will follow up with whatever info is needed. That way others reading this will be fully informed and kept up to date as well.

OK, first of all our upgrades are totally "passive" in nature as we do NOT get involved in changing any critical active circuit components like IC's, transistors, etc., nor do we engage in the practice of altering the fundamental circuitry in any way. Essentially, we do those things that are labor-intensive because they cannot be easily automated, as is common nowadays with circuit board assembly.

As a little side note, upon review one will find that as a consequence of advances in robotics technology, most electronic fabrication and assembly processes are now being streamlined so as to require an absolute minimum of manual labor. Specifically, as the requirement to keep the retail price of a given product as low as possible increases (as in affordable high-end audio products), so too does the need to minimize the amount of manual labor required in the production of that product accordingly.

Yet, there always remains certain processes that, because of the low to moderate sales volumes involved, the investment required to automate them cannot be justified. Therefore, in the manufacture of most any product there will always remain some minimal amount of manual labor required to to fabricate certain parts and/or assemble the completed product. It is in these areas wherein modifications to the existing product can often be made to good effect. By investing (mostly) a good bit of additional labor and a few key materials to make relatively simple modifications one can often increase the product's audio performance considerably.

Conversely, were the manufacturer themselves to make these same modifications to every unit within a given model group or series at the factory, in the vast majority of cases doing so would only serve to reduce the total profitability of the product. That's because even though the product may now offer somewhat better performance, the resulting higher MSRP required would work to sufficiently reduce the total overall sales volume such that it would offset any related profits gained from the effort.

That single fact alone then leaves open the opportunity for a smaller entity operating under far less overhead (such as TDSS) to come along and offer a modification service for the express purpose of extracting the full "latent" potential that these otherwise already excellent products have to offer by doing those things that the factory cannot afford to do. In so doing, the market then benefits doubly because the majority of enthusiasts that are more budget conscious can obtain the lion's share of whatever performance the product has to offer at a lower cost, while those of fewer numbers seeking to experience the best possible performance have the option of doing so with minimal added investment.

 

In light of the above, TDSS: https://www.mytdss.com/consumer-home


... offers what we call our Dynamic Resolution Recovery Technology in the form of our D.R.R.T. Upgrade: https://www.mytdss.com/drrt


There is a TON of technical and other information in the above link, which is grouped into 3 sub-sections. So, for those that would prefer to bypass all that and get down to the basics, you will find a short summary at the following page: https://www.mytdss.com/the-skinny-on-drrt


Then we have compiled a list of reviews that have been so kindly provided by our customers that can be found at the following page - NuPrime Listener Reviews: https://www.mytdss.com/nuprime-reviews


Please Note:
The TDSS D.R.R.T. Upgrade is FACTORY AUTHORIZED BY NUPRIME, and thus it does not void or otherwise affect the manufacturer's Original Warranty whatsoever. Furthermore, TDSS provides an additional 1-year (from the date of upgrade) Parts & Labor Warranty and a LIFETIME Labor-only Warranty that is also transferable.


Also included is our TDSS "Certificate of Conformance" that accompanies each unit. On it will be the Model & Serial number of the upgraded product, the date, your name type-written and our signature. Should you ever sell the component then you will want to forward this certificate to the new owner, as it is their proof of purchase for obtaining future warranty service.
See a sample certificate here: https://www.mytdss.com/tdss-custom-upgrade-certificate-of-conformance


While perusing our website you are likely to come across a good bit of information regarding the various upgrades that we offer for the older NuForce products as well. Specifically, you can find the bulk of the information about the NuForce Reference Series Amplifier Upgrades at the following link: https://www.mytdss.com/ref-series-upgrades


Also, there are a number of review written by our customers that you can find on the following NuForce Listener Reviews page: https://www.mytdss.com/nuforce-reviews


Due to the fact that our upgrades are all "passive," they treat the kind of problems that are common to ALL audio components EQUALLY. That said, they are just as effective when applied to other brands as we have proven to be the case with respect to those products from NuForce & NuPrime. In fact, we installed our D.R.R.T. Upgrade into a pair of highly regarded Benchmark AHB-2 amplifiers:

Benchmark AHB2 Power Amplifier


As you will read, the effort turned out to produce very good results -

TDSS & Benchmark AHB-2 by Roger K. : https://www.mytdss.com/tdss-benchmark-ahb2

... even more so than we had anticipated, because if you research that amplifier's specifications you will find that Benchmark already touts the AHB-2 as having a Signal-to-Noise ratio of a WHOPPING 130 dB!!!

 
If you check into things a little further you will then be as puzzled as we are with respect to how they were even able to measure a SNR that large, because one of the most advanced audio test instruments available (for over $28K), the Audio PrecisionAPx555 B, is advertised as only being able to measure noise down to -117 dB. 


So go figure. In any case, "IF" our D.R.R.T. Upgrade can not only improve the NuForce & NuPrime gear as well as it has been repeatedly shown to do, but also an amplifier like the AHB-2 that sports a SNR of 130 dB... then you can probably figure it should do a pretty darn good job on just about ANY component that you might own.


If interested, our pricing for generic audio components can be found here - TDSS D.R.R.T. Upgrade Pricing: https://www.mytdss.com/upgrade-pricing  


Finally, just in case you didn't know, Coyote Sound: https://coyote-sound.com/

... is a TDSS affiliate and online reseller of NuPrime products. Working together with us they are making all NuPrime products available with the D.R.R.T Upgrade included at standard MSRP pricing. In other words, if you purchase a NuPrime product from Coyote Sound you have the option of having the D.R.R.T. Upgrade installed by us prior to it being shipped to you at...

NO EXTRA CHARGE!!!
w/ FREE SHIPPING INCLUDED!
(Continental USA-only)


Purchase the Evolution DAC and a pair of Evolution One mono-block amps from Coyote Sound and hear them in their true, full & AMAZING glory... and not pay one extra penny for it - or shipping either!


If those are a bit outside your budget but you still need a KILLER PAIR OF MONO-BLOCK AMPS... then get prepared for the deal of a lifetime, as a pair of D.R.R.T. Upgraded NuPrime-X MCX 1's. A
t 750 WRMS and only $1,295.00 each/$2,590.00 per pair, will...

BLOW YOUR FRICK'N $#*! AWAY BABY!!!


Being based on the same core technology as NuPrime's other amps, we're talking just plain "STUPID GOOD" for the money - PERIOD. Peak Dynamics that  - "even though you know it's coming" - will still make you flinch EVERY TIME, enough RMS power to host your own live concert in your back yard (not to mention blow the heck out of your woofers if you don't use some common sense), and the kind of "neutral-yet-natural" sound and extreme resolution that all NuPrime products are known for... and there isn't a better deal short of stealing a pair from your audiophile buddy's house when he's not home :-)) That *could* get a bit too "expensive" in the long run though (if you happen to get caught), so instead we advise that you just contact Coyote Sound and they'll get you set up... and thereby maybe save you from some "free, long-term housing" at your local Sheriff's facilities too. 😆


If you have any questions just ask somebody else. Oh wait... I'm the only guy that can answer your questions, so I guess I'll have to be the one. Just be careful what you ask for though, as I do have a "touch" of OCD and tend to be uh, shall we say... exceptionally thorough? 😎


I'll be standing by. Thanks for your interest, have a great day and...


Take care,

Bob Smith

Can someone pm me with a little more details on what is done. I would consider the tdss upgrades but I would need to know what is actually done to the evo amps and dacs.

Hi Bob, 

How would you compare the mod st10 with the st10m? 

Am currently using the st10 and wondering which direction to go. 

Thanks

Hi sresener,

The treatments that comprise our D.R.R.T. Upgrade as employed in the Evolution products as well as all other NuPrime models and those of other brands are as follows:

 

1) (Amplifiers Only) We replace the output wiring coming from the amplifier board going to the speaker terminals with our own proprietary Laminated Metal-foil Cables or Silver + Zero-Resonance Alloy composite wire.
2) Shield and ground all internal wires & cables following established RF engineering practices for optimized remediation of stray EM radiation.
3) Magnetically shield key circuit components and other locations based upon and being guided by EM probe testing.
4) Apply mechanical damping material on circuit boards and other key points based upon and being guided by the results of accelerometer testing.

 

If you would like more in-depth technical information regarding each of the above treatments please see the following pages from our website:

 

What Is Audio Dirt?
https://www.mytdss.com/what-is-audio-dirt  

 

Combating Stubborn Audio DIRT with D.R.R.T.
https://www.mytdss.com/combatting-stubborn-dirt-with-drrt-continued

 

Just about everything you could possibly want to know (and then some) is contained in the above two web pages. Going beyond that to provide more “detail,” we would just about have to write a “primer” for teaching others exactly what to do and how to do it.

 

Although except for the compound wiring that we sometimes use as mentioned in #1 above, for the most parts the methods we use are not particularly “proprietary” to TDSS. Rather, they are well-established methods often used in electronics industry.

 

On the other hand, in several aspects these techniques are not exactly “simple” either – especially when it comes to treating EM radiation artifacts at Radio Frequencies. In fact, there are MANY digital hardware designers out there that even tough they may be very well versed in digital design methods, often they have little clue with respect to those peripheral issues that must be considered as a consequence of working with high energy/high frequency square waves that operate well into the Radio Frequency band. That said, we have divulged about all we are going to share about the subject on our website and in particular, on the above two pages within it.

 

You see, we have spent years studying and learning the techniques that we use in our upgrades, so if you want to know more you’ll just have to do your own work and figure the stuff out for yourself like we did. Maybe get a book or take some college courses on the subject because we are not about to help “train” the competition in how to duplicate the results that we achieve. Sorry.

 

In closing, we don’t mean to be “smug” about the subject, but from time-to-time we end up receiving comments like those of RafaPolit that posted a follow-up comment on the thread you started on AudioCircle stating:

“Wow... I honestly read and skipped for about 8 or 10 minutes and did not find a single piece of concrete information of what the actually change / improve. Diagnostics, pointing out issues and claiming it's all passive, but no actual info. Did I look wrong?”

 

Our comment would be: You're kidding - right? Did you actually go to any of the web page links that we provided in our original posting? It’s all there, and I can guarantee you it’s more than you can read in 8 or 10 minutes – that’s for sure. In fact, in those and the other linked pages within there is more technical detail and information than many audiophiles can even intellectually digest, let alone care to know. Going beyond that would be superfluous and require almost the equivalent of divulging the processes that we go through on a step-by-step basis – which ain’t gonna happen.

 

Oh, and if you want measurement data then we would ask that you please loan us your Audio Precision APx555 B audio analyzer (at MSRP $28,300.00) or the equivalent thereof and we will gladly provide them for you. Ooops… never mind. Gotta take that back. The APx555 B doesn’t have the degree of resolution needed to fully document the effects that our upgrades have and (ostensibly) it's the best analyzer out there. There is no doubt that it is good enough to document a large percentage thereof, but if were gonna bother I want the WHOLE story – not just part of it.

 

You see, there has been WAY too much of that crap since the audio hobby began. Remember when “TIM” Distortion” was the “new kid on the block” and all the rage? Before that the standard SMPTE 60Hz/7KHz test was “all that was needed” to completely delineate the performance of an amplifier. Oh, we’ll get there – SOMEDAY. But we ain’t there yet so for now there’s no point in wasting the time. We have the best damn NATURAL INTELLIGENCE (as opposed to AI) – based audio analysis systems that one can get sitting on top of our shoulders. It's pretty "sophisticated" too, so like any SOTA piece of test gear you'll need to take a good bit of time to get familiar with it and LEARN HOW TO FRICK'N USE IT CORRECTLY!!! I guess that takes more work though than being spoon-fed the "metaphorical equivalent of listening" in the form of "numbers" that you've been TOLD reflect the actual EXPERIENCE of LISTENING.

 

As a little side note, here's a rhetorical question for everybody of "specification-minded thought paralysis," (or anybody else that cares) to ponder:

How many audiophile's do you suppose have EVER listened to a LIVE, UN-AMPLIFIED concert, such as a live orchestra or even small jazz combo. Whatever will do, so long as NO ELECTRONIC COMPONENTS LOUDSPEAKERS OR AMPLIFIERS WERE INVOLVED WHATSOEVER?

 

Not many, eh? Yeah... that's what I thought. Now back to the subject at hand:

 

So instead of fooling around trying to “pick the fly poop out of the pepper” by interpreting numerical and/or graphical test data that is only intended to REPRESENT audio signals, that 90% of which resides within or about the NOISE FLOOR of a system, we’ll just stick with the same two pointy little “analyzers” that God saw fit to affix upon either side of our beanie heads and call it “good” for now.

 

Furthermore, we suggest that others of skeptical persuasion try that too, because at least then we’ll all be on the same frick’n page. Otherwise, if you ain’t got no functioning ears then what the heck are we doing wasting time here talking about any of it for - "specs be damned"?

(And this is coming from a guy that once worked with some of the most advanced audio electronics in the world, not to mention working with and having one of the world's greatest electronics genius' as his mentor for several years).

 

 

Hey rtanwm,

How would you compare the mod st10 with the st10m?
Am currently using the st10 and wondering which direction to go.

 

Do you mean in the case wherein BOTH models have been upgraded? If so, then the 10M sounds better in direct proportion to the extra power that it provides as that power becomes needed; the same as if neither model had been upgraded. The upgrade Adds NOTHING to the sound. Rather it is a set of totally SUBTRACTIVE processes that REMOVE unwanted, performance-degrading artifacts – i.e., DISTORTION (albeit, extremely low levels thereof).

 

Therefore, if you have an ST-10 that has been upgraded and compare it to a 10M that has not, then up to some power level wherein clipping distortion just begins to set in the ST-10 WILL SOUND BETTER than the 10M. After that point though the 10M will take the lead and start sounding better, but only because the ST-10 is now producing more distortion and starting to sound worse. Make sense?

 

While some have sworn that our upgrades increase the power output of an amplifier by some small amount, the effect is pretty much psycho-acoustic in nature. That’s because the laminated copper-foil cables that we sometimes use to replace the standard output wiring going to the speaker binding posts “MIGHT” increase the output by 0.1dB at MOST – and that’s just an optimistic speculation on my part. The odds are it has no AUDIBLE affect whatsoever on the total amount of power being made available to the speakers.

 

Sure, as you lower the series impedance of a conductor more power will be delivered to the load, so there will be some small increase in power, but based on past human hearing tests the “academic community” will tell you that such a small increase in power output would not be audible to a human being.

 

Other than that, if both amplifiers are operated BELOW THE ONSET OF CLIPPING, then if both are upgraded they will both sound about as identical as you can get… seeing that they are simply two slightly different versions of the SAME AMPLIFIER.

 

In that, our D.R.R.T. stands for DYNAMIC RESOLUTION RECOVERY TECHNOLOGY. In other words, it helps to "recover" or make those low-level audio signals that reside down near the bottom of the music's dynamic range (where noise typically resides) more audible. Simple as that.

 

So, what’s down there at such low levels that you can actually hear? Probably more than you EVER REALIZED. That’s WHY our upgrades have been such a huge success. Finding out is fun!

 

I hope the above helps. Have a great week ahead and…

 

Take care all 😀 
-Bob

Hey sresener,

From Posting on AudioCircle:

I asked with no response but it seems really odd that it can not be discussed here. 

Yeah... and that's the way things will remain for the foreseeable future. You see, back in 2015 after many years of having had my own forum there, John Ricci (administrator/owner/ "The Borg - RESISTANCE IS FUTILE" of AC) "banned me for life" from his forum. Why? Your best bet would be to ask him directly because, well... obviously I'm not likely to be very objective in my view of the matter. Besides, seeing that he has been the administrator of an, ahem... "PUBLIC" audio forum for so many years (decades now), he's bound to be a better judge of character than I am. 😎 

If you don't want to BELIEVE him though, just ask others (like my customers) that ACTUALLY KNOW me. Yeah, they're certain to tell you what a mean-spirited, rotten SOB I am, and how arrogant and "thin-skinned" I am such that I'll "really let you have it" in less than a heartbeat if you do or say something to piss me off - which typically requires going to the EXTREMES of making an outright attempt at harming my family or friends, defrauding me or casting false aspersions upon my character. Yeah... you probably don't want to do any of that EITHER or else you will likely be "banning" me from your own private little universe TOO.

Regardless, we've been doing FINE ever since, so it's probably best to just "leave dead dogs lying." They say "good fences make good neighbors" so, NOW... it's all good between little Johnny and me. 😀 Besides, Internet cyberspace is an awful big place, so folks usually manage to find what they are looking for and/or get their message out... one way or the other.

 

 If I was a betting man I would think its a simple power cable and fuse upgrade. (for the evolution line)

FUSES? We don't do no stinking fuses! :-)) We have nothing against them though - "Everything matters, if anything matters at all."

CABLES? You have to pay extra for those:

Aether Audio Mobile Bus-bar AC Power Cables (MBB-AC)

PS. The picture in the above link is no longer completely valid (new pic coming soon). While the body of the cable remains the same, the end connectors and flexible sections shown have now been changed. Instead, the production units will come with some nice "Red Copper" connectors that can easily be be removed/replaced (as opposed to the permanently molded ones shown in the picture) and the flexible end is a full, braided, tinned-copper shield covered with clear tubing.

In addition to the above, we are also offering them with whatever Furutech connectors that you may want as an optional upgrade. Thanks for asking and...

Take care,
-Bob
