I have a behringer 4700

It has a bit of hum to it, but it is quite flexible and pack plenty of power. For $100 it does the job for me.
If you want the ultimate sound, this ain't it. If you want functional, flexible, and affordable, it's worth a look.

Check out the OZ Audio HM-6. It's basically a matrix mixer which allows you to get 6 completely different headphone mixes using up to 6 different sources.
I love mine because I got it for $150 off of Ebay and it came with a Megadeath certificate of authenticity. Apparently they used it during the "the world needs a hero" tour.
The certificate is hanging above the urinal in my studio's restroom.
Classic!

p.s. I'm not advocating Ebay, lately I've gotten some pretty questionable results.

Hope this helps,

thanks for the replies...i was looking into the oz amp actually...and oddly enough the behringer was 2nd on my list so far...have to look further into it.

any suggestions on actual headphones for usage described in my original post? that is...

I'm looking for something for recording individual and live mixes with my band...

cheapo sony studio headphones? more me phones? extreme isolation? suggestions?

I have the Samson. I have had pretty good results with it. Controllable, with no noise that I can hear. I also think RANE makes one that is a little more expensive. The only thing is that it only has one set of inputs. Sometimes I wish it had more.

the rolls 4 ch one is about $79- just a little box that works great

yea if i'm mainly just tracking with the amp, i'm going to need at least 4 channels...

nobody likes commenting on headphones. i've personally only got one pair that i've been sort of using studiowise, a pair of koss r-80's...they're not bad, exhausing on the ears after relatively short times though...external phone jack cord broke off and is taped to the one side and all...brutal. time for a replacement...here's where the knowledgeable users of recording.org come in :wink:

try the seinheiser 280 cans- great for tracking drums (great isolation) and vocals (no leakage!) for 100 bucs-
Also, for extra headphones
you can't beat the AKG k44 for about $20 ea- every studio should have a few (and they sound decent to boot!)

I've been using the Furman HDS6 Headphone amp for a few years now and love it. I feed it with one of the stereo foldbacks from the board for an overall mix, then feed the four individual channels with sub buses from the board. I'm using three of the HR-6 satellite stations. They connect to each other and the base unit via CAT5 cabling and be routed to various spots around the room.

Works great.

I guess the main consensus aroound here is that headphone amps are not so critical and most of them will do. They don't affect the sound being recorded- good thing, or we would have another expensive thing to buy- on the subject of expensive though, and if you must have an expensive headphone amp, yo can always buy the Grace for $1,400- That's right, $1,400.00, not $140.00

I'm partial to AKG K240's. They sound great and they're the most comfortable I've ever worn. I've had them for so long I don't think I could do without them.

For vocals the Senn's that Xavier recomended are great. I just tried a friends pair and they are on my shopping list for the same reasons Xavier suggested.

If you really want extreme isolation for setting up mics and such, try this. Get a pair of -30db hearing protectors ($20 to $30 at Grainger) and wear a pair of earbuds underneath them, for isolation you won't believe. I don't have a control room so this is my only option for setting up the mics. The sound isn't extremely accurate (isn't that what monitors are for) but it's more than enough to find the sweet spot for a mic and at less than half of the price for those Extreme Isolation Phones.

Hope this helps
