Transcendent "The Masterpiece" Preamp feedback?

I've been wondering the same thing. I built the GG preamp a couple of years ago, using substantially better output caps, silver hookup wire, Goldpoint attenuator and selector switch, and NOS Amperex 12AU7 tubes. It is simply a great sounding line stage, and deathly silent.

Makes me wonder how much better "The Masterpiece" can be. Hopefully, someone who's built one will respond.

I thought the GG was one Hell of a deal, great "bang for the buck", was curious, bought the Masterpiece, & feel like the latter was better, well worth the cost. I will add that the Masterpiece was a more difficult build-no printed circuit boards, leads of  resisters & caps soldered directly to socket pins & terminal strips, close enough together to connect & short if you're not careful, more than my old eyes could handle without magnifier, but well worth the effort & time. The GG is currently gathering dust & lonely.
I don't pretend to be an expert, just my opinion. If you're curious, hope you try it out & have similar experience.

Thanks for the snippet of your experience with the Masterpiece, Jay. I am not too worried about the complexity of the build, but thats good to know.

Can you give us an idea of how the Masterpiece sounds? I don't know how the GG sounds since I never heard one, but I am really interested in the sonics of the Masterpiece with it's 300b tubes. What is the midrange like? How is the soundstage (holographic or not, height, width, depth, etc)? How about speed, frequency extension on the highs and lows, etc. you get the idea!
