Nice little circuit that adds body and improves sound stage. I made it as unity gain. Thank you to Nelson.
Beautiful sound, beautiful in its simplicity. Mr. Pass has taken all the guesswork out of selecting the jfets. Ridiculously low price, easy build, with stunning results. Dead silent. Rich, natural sound. Will probably end up building one or two more.
Simple device that works great. It was a quick and fun to assemble. It really enhances the overall sound quality.
I ended up building three of the kits, one as a stereo version, using RCA's with unity gain, so it could be used inline from a preamp to an amplifier. The other two kits, I built a Balanced version, one kit for each channel, once again with unity gain so it could be used inline from my Balance BA2018 preamp to my ALEPH J amplifier. All of these projects were built using parts and enclosures from the DIY audiostore.
Hello it works well, improves the sound stage, the presence and placement of the instruments. I recommend it to try.
Very useful item, great fun.
