Hmm, it seems I am being mentioned here re: parts. Let me just make a few things clear regarding my choices and preferences. The Sonicap Gen 1 with Platinum bypass is excellent. I was perfectly happy with it for a long time. But lately I've been chasing down 2 ideas.
First, I wanted to aggressively go after resonance, and caps & coils were 2 areas where I see at least 2 manufacturers had made serious attempts at just that issue. So I decided to try the Clarity Cap MRs and the Jantzen wax copper foil inductors.
Second, I wanted to get away from bypass caps completely and just have my main cap do all the work, so to speak. The Gen 1 was too warm and not detailed enough when I removed the platinum bypass cap. So the Clarity Cap MRs were put in place without bypass to see if they would be a good fit without a bypass on them. They were a great fit. But keep in mind that I also run a slightly warm sounding DAC and a warm sounding tube preamp (using RCA 6sn7 tubes warms things up nicely) and perhaps one of the smoothest and most musical sounding SS amp on the planet (the Pass designed Burning Amp 3). So for me the ultra clarity and ultra transparency were perfect. Lost the warmth of the Gen 1 caps, but in my system I didn't really need it.
Maybe one day I'll experiment again with bypass caps (perhaps some Jupiters), but for now I'll stick with the MRs alone.
And Danny is right - if we can get the same design but American made, I'm all for that. I think the main point with the Jantzen is the wax used for resonance control, that's what makes them special. If someone local can take that basic idea and make it even better (like better copper quality for example), then we all win. I know I'd buy it in a heartbeat.
OK, sorry for taking this thread even further off topic....
