Headphone connect direct to Amp

I believe that the AKG K1000 headphones connect directly to the speaker post of an amp.

ck out headfi.com any headphones can connect to the posts the problem is that the amps are not made to put out .5w of power it usally takes several whatts to get a rich sound which would blow the headphone. You could put in a resester but that changes the sound. You could try comming out of the pre out. But the best bet is get a headphone amp.

Youu may find a off brand set that could handel a couple of whatts but I do not konw of any "good" phones that will.

There are adaptors by Russound, Antique Sound Labs and others that will allow you to do this with headphones for about $100. This way, you can use any headphones.
The other option, if your pre-amp has enough output voltage, is to buy coax to 1/4" or 1/8" adaptors at radio shack so you can hook up your headphones directly to the pre-amp outputs and skip the amp altogether. Beware, some headphones are much easier to drive than others.

Antique Sound labs makes a box for that purpose. Check the web site. Has a switch to direct speaker output to headphone or speakers. Sells for about 150. Just picked up a similar type unit from a fellow AGOer's by Russound, which is no longer in production. Far too many pre amps and amps no longer have a headphone output. Some integrated amps have not even a tape output or aux out in which you could employ the use of a headphone amp.

AKG K1000s hooked up to a Cary 300b or 2A3 integrated is a combo made in heaven. They are designed to run off the speaker posts, but with a custom adapter can run off the 1/4" jack.
