"well...

I practice what I preach.

As I type away here I am listening to my new TDSS modified ST-10.  Its burning in only for a few days. 

I know how the TDSS mods effected positively the sound of my older NuForce components. So, this time around I did not waste time.

Just the same.  The ST-10 without the mod is a great sounding amp.  The TDSS mod is simply a refinement that I know I can not go wrong with.  For the TDSS mod was originally designed to add reliability and longevity to the component.  It was to cause greater reliability. Turns out it also made the equipment sound better.  That is why the mod now comes with a lifetime transferable warranty.  I was very surprised when I found that in the box.

 

Update 2:

(Excerpt from posting)


... As far as the TDDS mods improving things?  I have two components from the pre-Nuprime era.  When it was still NuForce.  I have an excellent NuForce amp and preamp.  These had the same design team now with NuPrime.  I had them for about a year and a half before moving to the TDDS mod.  By then I knew the units very well. That way I easily heard the differences after the mod. A good difference.  But first I would suggest you get yourself very accustomed to what you have by listening many times to the music you like.   (I believe even without the mod, the ST-10 differences will be made apparent.) Then if you upgrade to the TDSS mod?  You can intimately know what it does.   Then the improvements will become apparent. Its not some brutal change.  Its a somewhat more of a subtle change that gives you a greater sense of the musicians performing in their own space.. and a certain smoothness that was not there before.   A clarity.  More like real music.

I will tell you one thing that the TDSS mod did that made me really take notice. 

I used to always use to listen using the equivalent of the AudioPrism ground controls.  http://www.positive-feedback.com/Issue57/audioprism.htm  The ground controls always made the music sound more alive. After hearing what they could do, I did not like listening without them.  But, after the TDSS mod? They had no more effect on what I heard.  And, it sounded better now without them than they ever did when they would change the sound before the mod.  I still shake my head at that one.

The mod (from what I understand) deals with neutralizing internal conflicts of electronic noise generated inside the equipment while playing. Fixing that right away gives you a quieter background.

A while back I auditioned an ST-10 and wrote a review in this forum.  I know what the ST-10 can do.  And, that is why I am expecting shipment of mine in the next few days.  And, since I already knew what the TDSS mods can do?  I ordered it with the TDSS mod. 

Here is the ST-10 review I did.. http://www.audiocircle.com/index.php?topic=134516.msg1428384#msg1428384"
