Review of TDSS Upgraded
NuForce Ref-20 by Chris K.

(Level-3 Upgrade)

 

From Email:

"With the new power supplies into the amps has taken quite a bit of breakin. That is why I have been quiet. 

I want to give you some initial observations. First, the amp has so much more dynamic range than before the upgrade. The amount of bass drive is amazing. 

It's as if a subwoofer has been installed into the system! Not just more bass but clean, defined and more realistic toe tapping sound. I also detect a bit less sibilance in the midrange, ever so slight but really in a good way. Soundstage is a bit more forward but a tad wider than before. Absolute non fatiguing sound.

The music really draws you in and gives me the desire to listen for long periods at a time. 

Within the next few weeks I am going to compare the amps to a friend's pair of Ref 20s. That should be interesting, especially since his speakers are a bit power-hungry. (Revel Studios)   

I will be sure to let you know how the test goes! Many thanks for talking me into the upgrade!!!"
