Review of TDSS Upgraded
NuForce Ref-9 by Richard V. (Part-1)
(D.R.R.T./Level-1 Upgrade Only)
I've been so busy playing with the new tweaks on my turntable, that I haven't gotten back to you about the upgraded amps.
In short, they are wonderful!
The sound is everything you said and more! The power is there and so is the sweetness without a trace of harshness. Just beautiful!
