Well I had to get more information. I envy those who got to see and listen to the new amp.
The gain settings are, 2, 6 and 11, with a switch on board accessed from top, lithium ion, 60 hours of playback, 250mA output for each channel. The size is 1/2 inch shorter than the TH. There are two 50uf caps one for the + and -, which means your real reserve is in the battery. 200 units for Christmas with a special price below the $375 that it will sell for.
Most all of the colors you have seen on Ray's site. This is fun stuff!
I just don't see this as being any more portable than the Tomahawk I own and I don't have any headphones that require a gain of 11. Unless the sound quality is out of the park better than the Tomahawk I don't see any reason for me to change.
