Best headphone amp for new Senn 650's

Thanks for the responses. I've been sucked into a vortex of insanity over at head-fi. I'm now learning about all these custom-made esoteric little gems like the SinglePower, the Larocca Audio PPA or something, the Gilmore V2, the Emmaline something or other, and the German RKV that looks awesome, but one member posted pictures of his after it burnt up somehow. I wonder if that's a common complaint with the RKV? Swampwalker, I know you're a regular over at head-fi, I saw your name on a lot of threads, what do you know about these other, custom amps? The MicroZotl is another one, and I've seen it come up for sale here from time to time. I'll probably give one of these lesser-known, tweaked jobs a try before investing in a new Headroom, given all I've read so far. Too bad I only have two ears, and one head.

The best? If you like tubes, then the best is a Cary 300sei (a lot of bucks!). Now, this is true for me; to my ears. Next best? Earmax Pro.

The Grace sounds fine but it is definitely solid state. The internal dac is not a very good one (sound-wise). The very high end HR Max stuff does sound very good (better than the grace) but also sounds solid state and costs way too much money. Just my two cents.

The Cary CAD300SEI is a killer headphone amp... definitely overkill on the high end of the scale $-wise, but excellent sounding. it and Senn 600s Kicked the butt of a Stax set up I had on audition for a while. Doubles as a great little integrated for small to medium room systems with speakers of 87db/1wm sensitivity or better. Add a CD player and it's a two-box system.

If you like tubes, try the Earmax Pro. I've been very satisfied with my Pro/Senn 600s. The tube combination I've found to my liking is Telefunken 12AT7 and Bugle Boy 6DJ8's. I could listen for hours (and do)!

Try the Musical Fidelity V3 . It is amazing! and under $ 400.00
