This is a constantly evolving system. My audiophile passion started in the early 70's and got me to study electronics and acoustics in college. I built my own speakers and power amps in the late 70's, but as my income increased and my free time evaporated, I moved to commercial products. I've owned at least a dozen of every different kind of component (probably more speakers) over the years. In the late 90's, I started focusing on home theater, but my interest in 2-channel has been rekindled in recent years.
I ended up spending my career in computers, but have started doing more DIY audio stuff recently. In the past few years, I've built three pair of speakers, two pair of subwoofers, two preamps, one stereo amp, four pair of monoblock amps, a Roon server, and several speaker cables, interconnects, and power cables.
My main system, shown here, is built with DIY preamp, monoblock amps, and speakers. I am hoping to build my own streamer and DAC over the next year or so, but I have two more preamp projects in the works that I need to finish first.
Accepts digital audio from numerous inputs. Buffers and reclocks the data, and outputs on numerous outputs including i2s, AES, SPDIF, optical, coax, USB. Inputs are opto-isolated for improved noise rejection.

Very nice system! I have no doubt it brings you may hours of pleasure. In my previous system I had taken my speaker crossover outboard, using Duelund CAST-Cu capacitors, and Mundorf inductors and M-Resist resistors... so your crossover really caught my attention! Nicely done. You obviously know how big an impact a crossover like that has on a system. I have no doubt this is a sublime system. I also used to have KS-3035 speaker cables years ago before getting a wonderful deal on a pair of KS-6065's. Both are super nice cables.
