Did the Hacker found some photo's, schematics or sound impressions?
Schematics isn't a mystery since long time..... Wayne has pubished a blank version, but......

OK I have finally built and tested the production Pearl II boards.
Looks good. We will be ready to ship as soon as we figure out cost and how $ to lose on each one. Kit will be both boards and the semiconductors.
EQ curve is like the original Pearl within +\- .15 dB gain is higher at 52 dB.
Front end gain is 35 dB and 40 dB secondary with about -20 dB EQ loss.
The gain is higher than Pearl and can go even higher.
More to follow.
Please excuse me if this is a stupid question, but I am interested in building a phono stage with balanced output. Would it be possible to perhaps use two boards and have a balanced output with the Pearl II?
Thank you so much for making your work available to DIYers. It is great to have such well designed and supported projects to work on. I enjoyed building and using the B1 and I look forward to the Pearl II.

You could build an Ono, it is balanced.
There don't seem to be a lot of true balanced designs for phono preamps available to the DIY community, it must be a difficult to design and implement.
