Mainstream Phono Stages Incorporating Premium Branded PCB Parts - Do They Exist?

Great design and tightly tolerance parts are the key to higher performance.

One afternoon at DeJaVu Audio, I listened to a pair of Audio Note speakers, I think their model E, if that makes sense, being driven first by an AN Kegon amplifier (for sale then at ~$125K) and then by the AN Ongaku (probably around $80K). This was at least 20 years ago, so maybe prices are higher now if those amplifiers are still in production. Anyway, they both sounded very good, but there was a distinct difference between them having to do with tonal balance. I cannot recall exactly how they differed in their presentation of music on a speaker presumably designed to accommodate both, but my thought was if there is such a thing as "perfection", ought these two amplifiers to be nearly identical in sound quality? Anyway, if expensive parts per se are the way to Nirvana, surely AN products ought to be on the way.

The Link will also show one more modern take on a Boutique Component.

I myself have similar plans for a particular component to be used on my Pre Amp Build, one just can't get enough ideas from one source about where to utilise Panzerholz.

The ever growing band of advocates is marching on.

Pindac, it is possible to post that URL as a clickable link. Can you give that a try?

I second Groovey on the SunValley Phono stage.  If you get it prebuilt in Japan, it comes with VCaps and all the other internal components are pretty good quality.  The only downside of it is the MC section which is terrible.  Otherwise, top notch.  Don Sachs made (or maybe still makes) a phono stage where he uses the best components he can find.  If you want a balanced phono stage, Atma-Sphere makes one as an option for his line stage.
