I have a power supply that was upgraded with blackgate caps and a mainboard that was upgraded with triple stacked DAC chips, 2x BB OPA627AU on an soic adapter on the stereo outputs and well as Nichicon Muse caps replaced many or the stock caps and Blackgate NX caps on the stereo outputs. The BB chips require their own 9V dual rail PSU. I can include what I was using. PM me if interested
