This is the third build I made using the diyaudio.com paradise phonostage group buy pcbs and parts.

It's a 3 box, dual mono, phonostage with a bipolar shunt feeding each channel. The design is all discrete, apart from the op-amp that manages the offset servo. All transistors are matched to better than 1% across both channels and intra-channel. All resistors are .1% parts and the caps in the RIAA stage are matched to better than .1%

• It sounds way better than any bit of DIY should. So far I've built another 5 for friends and am about to start on the 6th.
  
  Pretty much everyone who hears it ends up wanting one.
