I went with the Alessandro MS-Pro for this very reason - they dont require a dedicated headphone amp. I have a custom headphone amp I had built a few years back, and they drive Senns and Beyerdynamics etc really nicely, but the MS Pros just dont need it.

The only problem with the MS Pro (which is a Grado but less harsh) is that when people have a listen they wont take the damn things off again.

Have to admit I hadn't heard of these before.
I have googled them and they look quite smart. The MS pros are only 32ohm impedance, I guess that is why just about any amp will run them!

How do they compare to Sennis and Beyers in terms of reproduction?
