Interesting. I built one shortly after the article came out (the mag was Stereophile) and I thought it sounded too "transistory" even after a long burn in time. It didn't sound bad but didn't warrant the over-the-top excitement in Corey's writeup IMO.
aunt corey buffer preamp
Well I finishes one of my winter projects. Got the buffer board with original buffers from ebay .you can get the board or get the blank board from the guy .One alps pot and power supply, and some tara labs wire later its working .sounds really nice. I remember the article in stereo review when it came out, and always wanted to try it. It needs to play for a while to burn in but it sounds pretty good, and I have owned a lot of preamps.
