Musical Fidelity M1 HPA? Good enough for Sennheiser HD 650?

I actually tried it and 2 more amps with the same headphone.

It was the M1-Hpa, HA-160 and Beta22. 

I really liked how the 650's sounded with the 160, nice detail, soundstage and clarity, followed closer by the Beta22. The M1hpa did a good job as well, but i felt something was missing (soundstage, less expansive?). I spent only some hours with it, maybe i need to have a more extended listening session. 

Thats my personal preference, if you have a chance to listen to it (or any of the ones listed), i recommend it. 

m1hpa and 160 there is a chance you can find in stores in Sthlm.

"I was in the mood for David Bowie so I popped in his "Diamond Dogs" CD. I love this-period Bowie, and "Rebel, Rebel" never gets old. His stinging guitar leads cut through better on the M1 HPA than they did with my Burson Audio HA-160 amp ($699). The impact of bass and drums scored a bit better as well with the HPA.

I'm not claiming there are day-and-night differences between the two amps, but the HPA was more rock-and-roll with my Sennheiser HD 650 full-size headphones, and that was even more evident with my Grado RS-1 headphones and the HPA."

I to was going to chose the Burson160d until i read a thread something about usb not being asynchronous or something Back to square one you got to have TRUST or else Hey dont expect to find to much of a straight forward answer ive been reading and reading and altough you get a general picture it basically come s down to you. if you cant ear what you like in your area your going to have to chance it.i guess  Like me I have been looking for an amp that would go well with denons d-5000 no clear winner  its down to 2 amps/dacs for me the BURSON HA 160D $1250.00  and the MUSICAL FIDELITY M1HPA AND M1 DAC FOR ABOUT $1635.00 in Canada. is the musical fidelity much better than the Burson i certainly dont know anyone.
