^ would love to see a portable amp from them too. Something that has enough power to drive my Q701 and HD-650.
I've found that most of my portable amps can drive the HD-650 easily, but not so much the Q701...
Also, it doesn't really need to be so small so that it has to fit in a pocket.
I certainly don't want a clone of the sound of an O2/Magni in a portable form. A TINY touch of warmth is OK. About similar to what you'd find in an E17 or Wolfson based DAC (I didn't like the E10 though).
PLEASE though...don't make the portable amp silver only! At least give us a black option for an additional price. Actually it's not that big of a deal.
A Modi 2 or something might be good. I can't afford a Bifrost and something around the $200 price range might be nice. Probably best to not call it the Modi 2. I really like the AKM DAC chip in the Modi.
I really don't know how you could improve on the Modi as it is and keep it cheap enough. I wish they had a cheaper DAC that was AC powered.
