I just bought a pair of HD25-1's and damn, they are even more efficient than I had thought. Right now I have the volume on my soundcard down to 2% - and that's plenty!

So... what would I need to build a volume controller with a 3.5mm output jack? As for input - RCA maybe? Obviously it doesn't have to be the best possible, but the less effect on the signal, the better.

The simplest thing would be an L-pad. There are some calculators online for the values of the resistors. Basically you put a resistor in line with the signal followed by a resistor to ground. It attenuates the signal without changing the impedence. I built a 60-ohm 10dB L-pad for my V6s because my D-2 Discman was too loud, even with the volume on MIN.

There are other designs, pi and T and some with capacitors. Guitar sites would probably talk about them more.

or you can just build a volume control with a 10k panasonic pot and some 3.5mm jacks and RCAs

This Headwize project would fit the bill.

Ill second pro's idea. I did that a while back because i hate pressing buttons to change the volume...analog rules.

Thanks for the help everyone. I'll need to check which pots the local electronics store carries in the morning,since they don't have an online catalogue yet.

edit:

Well, shoot. Of course they're closed this saturday... just my luck
