@charles1dad Regarding AS's review pieces, I don't know that he purposefully gets different pieces, but you can see his Franks' stock caps here:
http://www.high-endaudio.com/RC-Frankenstein.html. He's got a Solen FEP/SN coupling cap and a Solen SCR FEP decoupling cap. My newer Franks (made in 2015) had significantly lower value Solens in both positions. Either AS gets better parts or over time Blume has started using lower quality parts in the amps, who knows.
Also, please hang in there through the general negativity on the site. I miss the older days, but you're such a great resource to this place. Despite the above issues, I'm so happy that you have recommended Coincident gear, your ears have so improved my music experience. Sorry again for contributing to the negative atmosphere, I just think people should know the truth of the situation.
