T-Amp for headphones

alan-ralph · 15th June 2005, 11:30 PM

Hi,

Been playing around with a sonic impact T-amp and found that it makes a very nice headphone amp. You will have to check that your phones use 4 wires to the ear pads (2 per side), and cut the three pin plug off the cable, since you must not join the speaker -ve (black) connections together on the back of the amp. THe only mod I have done is to increase the input capacitors to 2.2uf.

Regards

Alan

What impedance are your phones? I was going to try it with my Grados, but I figured it'd be way too loud since they're only 32ohms.
