dedicated power amp for headphones

[PreSapian]

i'm quite fond of my mingda mc7r preamp and would be feeling wasteful if i wasn't using it to listen to my headphones. the preamp has two sets of outs- perfect for two sets of dedicated amps- one for my speakers, one for my headphones. what do you guys think? do such designs exist? a headphone amp without a volume pot. my inadequate searching tells me no...

use any headphone amp, just put the volume pot on it to the max and use preamp to control the level
whats a problem?

 

[PreSapian]

loss of fidelity?

99.99% of headphone amps have the volume control directly at the input. Therefore if you set the volume control to maximum it is effectively out of the circuit.

^thank you. that explains it.

Or,just omit the volume pot altogether. You may need to 'replace' it with some fixed resistors,to provide a ground reference and keep the input from floating.
