What headphone amp to buy-Sennheiser HD 600?


Well, thanks to the kindness and patience of my fellow A'gon-izers, the hook-up "problem" for the headphone amp I have is solved. The amp is a Ramsey SHA 1. The phones are Sennheiser HD 600. I had remembered that amp sounding great. Now I'm spoiled by the new speakers I have, and even though the signal path to the amp is thru the Dodson DAC, I still think it sounds........not so great. Decent I suppose, but harsh on the upper end, yet without the mitigating detail, and you know, just.....unsatisfactory.

OK, OK, so here's the question(s): What's a great, fairly cheap (like, at LEAST less than a grand) headphone amp? Sonically, I want EVERYTHING!!!! (Except soundstage, that has never happened for me with any headphones, ever, I'm pretty sure not even with the expensive Stax I heard a few years ago).
It MUST have: Tight, deep, fast, smooth, tonally correct, musical bass, shimmering, non-fatiguing, emminently smooth yet ultra detailed highs, great midbass punch with no boom or softness whatsoever, midrange that is totally natural, smooth, detailed, and lacking any hint whatsoever of grain or electronic amplification artifact in the upper registers. It should sound great on ALL program material, from classical to rock to bluegrass to new age to jazz, anything and everything.

Other than those relatively modest criteria, there are no other performance demands. :)))

So, fire away!

It's funny that you should mention the Stax line. I MAY have a line on some older but well cared for Stax Lamda Pro's, complete with a Stax vacuum tube amp ON THE CHEAP. Or, maybe not. Not totally sure yet.

So..........No remote, but I COULD buy reeeeeaalllly long Jaguar RCA's (5 meters) for 800, and MAYBE get these "earspeakers". Never thought I'd be able to afford high end Stax. Had been totally off my radar screen (I'm NOT Bill Gates, ya know....).

Any thoughts, IF it even materializes? Everyone, please, feel free to chime in.
p.s. to all kind and helpful A'gon-izers posting to this thread (which is HIGHLY appreciated, by the way): I didn't hear about this Stax steal "possibility" until today (12/23/05), AFTER starting this thread, and it may or may NOT be true (seeing is believing). So that's why this Stax question is added to the thread just now.
I found that the Stax phones which are circum-aural (they totally go over your ears and "seal" to your head to make my ears and head sweat! YMMV. The 650s are better than the 600s and the aftermarket cords are a real value. If you do end up with the Stax (which sound lovely), and want an extension headphone cable, drop me a line.
Give P.S Audio a listen.Normally I would say "TUBES" given they need almost none and one can roll them to there hearts content.But reading the Stereophile review of the new Intergrated and seeing there web site if you have then nearby give then a shot.Sounds like some pretty cutting edge tech going into more than there power conditioners.If theye made a table I might do a linn,Naim,Rega,thing with them and go with a one brand system since it's voiced together.but might go with the cebter and stick to Sony/VPI and something as the ultimate transducer at the speaker end.
Happy Holidays

Wow, given so many opinions it sounds like alot is left to personal taste or not alot of comparative listening. You may have to do the comparitive listening yourself, or go to the headfi.com forum and see what the total headphone geeks say!
