After many a moon, I finally finished my Pearl. I added volume and balance controls, a moving coil step-up transformer, and a switch for auxiliary inputs, so that the Pearl can serve as a passive preamp for the rest of my system, which includes a Hafler Transnova 9505, (at least until I retire and build my own set of upper and lower frequency Pass A75's to drive my Vandersteen 3A Signatures !!), and a Liteaudio DAC-60 tube DAC. I found a nice case and the last two Alps Black Beauties on the planet, so it makes for a nice package. I've enclosed a couple circuit schematics and some photos to share with the other DIYer's who enjoy your website. Please keep those GREAT projects coming !! Sincerely, Don Bingaman
