Welbourne Labs sells hybrid modules for players. They come with an outboard power supply, which is a very good idea. This way you can use a power cord optimized for the analog stage, and another for the digital. Same for PLCs.
The modules have a tube input, and mosfet output, no coupling capacitors, so they should give a nice full, somewhat more 3D sound.
