My main phono preamp is a 2-stage tube phono circuit with passive RIAA equalization. The first stage is a Siemens D3a (in triode) and the second is one-half of a 5687. Each tube is biased with LEDs. The outboard power supply uses a 5R4GY rectifier, several chokes, and Blackgate WKZ filter caps. The audio circuit uses a number of Audio Note Silver tantalum resistors. Interstage coupling caps are .1uf CuTF V-Caps. Intact Audio output transformers.
I experimented with a number of audio circuit topologies and power supply designs, as well as component types, before settling on this particular setup, so it's no surprise that I like its sound very much. It replaced an Artemis PH-1 as well as a number of previous DIY efforts. Aside from sound quality, it is also very quiet, more so than any of the 4 or 5 solid-state phonos I've tried.
