Hi Stickman451 - noticed no response yet to your post. I've heard the phono stage at several shows in different systems that all sounded great. Have one arriving in a few weeks. If still interested let me know and I'll post impressions
Hi - got RPS100 several months ago but was having system ground loop issues only on phono that caused analog to be unlistenable. Replaced my power conditioner with Vibex and now able to use -- just starting to use more regularly and could not be happier. Haven't started digging out my older vinyl and playing with the phono curves but as would be expected SQ takes a major leap forward over the solid state Ayre phono it replaced.
After a couple of months can report that the TW-Acustic RPS 100 sounds wonderful and works flawlessly. Using with the TW-A GT w/two TW-A 10.5 tonearms: Miyajima Madake Stereo (balanced) & Zero Mono (single-ended).
Biggest issue is that the TW-A analog front end sounds so great that many CD's are now almost unlistenable. So retracing my steps to re-acquire albums that I did have on vinyl but converted to CD due to space constraints, often at ridiculous prices. But it's worth it.
