Thanks Xan7hos. I will look into the Maple Tree.
I have a 'Magumn Enhanced' MS2i on the way from Canada. Supposedly the enhancement tames the stock trebble a bit. Perhaps it would be best to hear the phone first through my regular gear.
I had my eye on the Elekit TU882. It's thread paints quite a good picture.
Budget is kind of open, with the caveat that I assume it would be relatively easy to power Grados to their full potential without going over $700 or so.
Desktop real estate: the smaller the better. However, I have a Stax T1W on the desk, which may go, depending on how the new phones perform - and that's kinda big.
Cheers!
