I purchased his Special 6SN7 preamp about 4 years ago. Later his Transcend PP amplifier. Recently had Aric upgrade the Special so it is more like a souped up Transcend pre. As others herein have stated Aric is wonderful to work with. Highly recommended.
I also own a Pass XA25 amplifier which i swap out with the PP tube amplifier depending on the speaker under use. Aric or Pass for Fritz Carbon 7s, Pass for Magnapan LRS+ in a smallish room.
