TDSS D.R.R.T. Upgrade of NuPrime ST-10 BY Paul W.
Feel free to use any or all of the below as you see fit. I've had about a week to listen to my modified ST-10 so far and, although I believe the amp's still settling in, my overall initial impression is "WOOW"! And it's only getting better every day. Just so you know, I do own (I've been told) a very high resolution system. So yes, that should make more of a difference I would think.
"Anyway, with your D.R.R.T. Upgrades you have taken what was a $1,600 amp that sounded like a $5,000 amp and turned it into one that sounds (to me with my admittedly limited experience with expensive amps) like a $12,000 amp!
It's now just in another class. It's better in every way. Everything is so much clearer, cleaner more articulate and dynamic, dimensional and open - and just plain more real sounding. The music flows more effortlessly than I've ever heard before. Transients and sibilants are faster and cleaner and natural. Gone are the usual hifi-electronic artifacts that are so distracting. All that's left is the pure musical performance. Even imaging is more solid and distinct; and sound staging is more natural and cohesive, effortlessly revealing the venue's acoustics.
Obviously you've managed to lower the noise floor substantially. Heck, even bass is improved! I could use the cliche about lifting a veil and all. But you've managed to lift two veils! I could go on.... I'm re-listening to many of my CDs now and enjoying them in a whole new way. A tremendous success! Thank you, Bob! I'm glad I took your advice. I would absolutely recommend this upgrade to the NuPrime ST-10 power amplifier. It's a bargain! It's a no-brain er!
Thanks, Bob for this upgrade. It's a revelation!"
