+1 for the Litte Dot series of amps.
I have a
Little Dot MK II that I've owned for a couple of years. I love it. Really makes my HD-650's sing, just as EF has described.
It would appear that the
MK III is out now, which I'm assuming is an updated version.
And if you *do* buy one of these Little Dot's from eBay, that seller, 'Davidzhezhe' is one you want to do business with. I believe he is the official seller of these things. Shipping direct from China kind of freaked me out and I was a little hesitant. But I shouldn't have been. The transaction went as smoothly as anything you'd order from somewhere like Amazon. I'm very satisfied with the product and the service. I wouldn't hesitate to buy another one if I needed to.
Good luck!
