I've been playing around with different setups for a headphone amp based on different designs I've seen online (cmoy, a47) and one my dad threw together (sort of a cmoy with a much better power source and different resistor values) and am just trying to figure a few things out. The first amp I laid down was an ne5532 based amp which sounded quite good on my MS-1's, but I thought I'd play around some more so I added the buf634 chip into the circuit and replaced the 5532 with an opa2132. The sound was different, yet it didn't seem to really add a significant amount of power or anything.
I've been searching around with google and through these forums trying to figure out some stuff and I've learned that I really don't understand the difference in buffering and the a47 layout. They seem to be relatively similar. Yet I've read that the a47 somehow runs the opamps in a parallel.
I suppose my question is what exactly the difference is and how the current increase works in both methods.
I'm trying to figure out what sounds the best with these MS-1's. I have come to the quick conclusion that an amp makes a huge increase in sound... I just want some more advice on what to play around with to see what I like the best.
Thanks everyone this is my first headphone amp.... I've been playing around with electronics a little, but I really don't understand a lot of stuff about how the feedback loops and gain structures work...
