Review of TDSS Upgraded
NuForce Ref-9V3SE by John Casler of Summit AV
(D.R.R.T./Level-1 Upgrade Only)
"One of my former NuForce Customers has applied the TDSS Custom Upgrade to his NuForce Reference 9 SE v3 Monoblocs. He has always held their performance in high regard and really had no complaints of wild expectations. His primary motivation was to reduce the possibility of an accidental feedback loop and over heating, leading to failure. Well, I won't go into a long drawn out REVIEW of his comments, but, he has nothing but extreme praise for the perceived performance increases. In fact, he intends to send his second pair in for the Mod/Upgrade soon.
In addition to having fewer worries about amp failure (he had had 2 already) he said the SONIC DIFFERENCE is truly impressive. It looks like Dr. Bob has worked some magic here, and put some more smiles on some faces. I have NO IDEA what, if any performance numbers have changed, but it is clear that the sound emanates from a FAR BLACKER (Silent) Background. It was reported to me, from ears that I trust, that the Bass was improved and more detailed, the soundstage and images were more "alive", and the highs more "THERE" without any additional edge.
So if you have a pair of Ref 9's that could use a little "shape up", contact me, or Bob, and get the details."
