Hey Guys,
I'm building a new beefed up CMoy with loadsa modifications. It's a OPA637 with two BUF634 per channel. I was debating whether to use a single or double buffers per channel??? Any suggestions?? Would there be an audible difference and would there be any advantage in using two OPA637s per channel too?? I'm going to be using the amp with SR125s and HD580s. It's going to be powered by a 24V (400mA) regulated mains adaptor.
With regard to decoupling caps I was simply intending to use a 0.1uF multilayer ceramic capacitor going from the power supply rails connected directly to ground. Is that the correct use of decoupling caps??
Furthermore, with regard to the power supply, would there be any advantage in using the BF634 as a virtual ground buffer as opposed to the simple power supply circuit given in the CMoy Pocket Amp article??
Thanks in advance for any help anyone can offer!
