TDSS D.R.R.T. + Power Supply Upgrade of NuForce Ref-9 V3 SE by Jim D.



From Email:

"Hi Bob,

Sorry for the delay in emailing you.  I have been [personal information omitted].  

About the amps.  Wow!  They sound fantastic!!!  It is like the “old” NuForce Ref-9 SE’s after steroid treatments.  Everything I loved about the amps has been amplified (no pun intended).  The base is deeper, sound field is wider, midrange is warmer and the dynamics more pronounced.  It is like I purchased a brand new pair of mono blocks - not just having “upgraded” some old ones.

Moreover, the modified amps produce a sense of more amplifier power with even darker backgrounds.  I suspect the new power supply is responsible for a lot of the improvements I am hearing.  

As the circuits break in, the sound keeps improving.  

I love classical music (especially modern orchestral compositions)and normally would wait until the a new component has “warmed up” and broken in before playing complex and dynamic music.  The amps already sounded so good, I broke my rule and started listening to very demanding modern orchestra music only a few hours after setting them up.  WOW!!!  Nothing but non stop TRUTH and BEAUTY !!!

I really can’t describe the whole spectrum of audible improvements rendered by TDSS.  I would advise anyone thinking of moving up to a world class amplifier and not wanting to spend a fortune, to check out the TDSS website and find out how to do just that!

Bob, thanks again for everything.  I hope the above comments are useful to you.  I have attached a few shots of the amps and speakers that you can use at your discretion.

Merry Christmas and Happy New Year to you and your family!"
