I've been using a pair of inline attenuators thus far, but would like to modify the amp so that it'd work better with efficient headphones. The current gain values are 3/11, and I suspect something like 1/6 would be just fine. Not that there's any need to alter the higher gain value - I never use it.

Not surprisingly, I've no idea how to go about doing this modification. I can't give much base information for now, except that the amp uses a discrete design. Pictures would propably make a world of difference, but I won't have a camera unti the next day or two. Why post now? I'm impatient, at times.

Here's a link to the manufacturer's site anyhow...

Alright, I peeked inside to check the resistors' values. 102R's are used for low gain, 473R's for high. The pot is a 10K one.

I remember reading something about bypassing the resistor(s) to achieve unity gain... would that work in this case?
