This has been a while in the making.....11 years and a bit. Bought the boards on Diyaudio in 2008 and didn't have all the bits to build it so it was put aside. Designed by Russ White of Twisted Pear, it is two discrete opamp boards for a preamp/headphone amp. Just waiting for some pcb connectors and I can then fire it up. I intend to use it as a preamp. I didn't want to spend a vast amount on it and cases can put quite a dent in your pocket so I had kept the FR box hoping it would come in handy one day.
Once it is up and running I will report on the SQ.
