This preamp is built off of the DIY project described here:
Amazing preamp with a unique feature set: https://linearaudio.net/douglas-self-preamp-linear-audio-vol-5
Features:
2 XLR and 3 RCA inputs, relay switched
Balanced and SE outputs
Active variable gain. 3x gain for XLR (10dB), 1.5x for SE (4dB)
Max output ~10V (XLR)
HF and LF tone controls (defeatable)
Balance controls
Excellent measurements
Build notes:
Modushop Aluminum 1U Chassis (~17" x 9.5")
Front Panel Express, CNC-milled panels
Kilo USA milled aluminum knobs
Caps - Nichicon Muse (ES), Nichicon Fine Gold (FG), Wima MKP, RelCap Film & Foil Polystyrene
Binned the volume pot for best channel matching -- better than 0.2dB across the entire rotation
It ultimately cost me around $950 to build, since I had to remake both front and rear panels due to errors.
My asking price is $700 + $20 flat rate US shipping.
Reason for sale -- recently bought a Benchmark LA4 to go with my AHB2/DAC3.
