I sometimes post on Audiogon as SpatialKing as well. I no longer work in the audio industry although I did in the past doing design work for preamps and power amps. Nowadays I work in green energy doing design work with filters, signal processing, and control electronics, all of which is pure analog. I have two BSEE degrees in engineering, one focuses on analog circuit design and the other focuses on embedded processing.
My equipment mostly Conrad Johnson tubes, Shahinian Diapazions with quad subwoofers. I have several preamps some of which I bought and some of which are my design. Recently I started looking at power cable design and line filtering.
