I'm leaning towards a Eastern Electric Minimax. I'm concerned about buying something without a tube option on the output stage. And the EE has great reviews and word of mouth.
I tried the currently popular Bryston DAC (borrowed from a friend). Via SPDIF it was a serious step up from the Touch in terms of detail, nuance and staging. It did sound great. However the Touch is damn nice in terms of sounding natural - nice timbre - which makes it non-trivial to beat in a meaninful way. The Bryston was clearly more of a high end sound. BTW the Bryston requires some kind of reclocking device for the USB input, per my experience with it.
As for the Eastern Electric, we shall see :-)
