I also owned a Portal Panache for a while a few years ago and liked it very much. It does not have the detail and refinement of the best gear, but it has coherence, drive, and a pure, direct sound that I liked very much. Stunningly good headphone amp, as someone noted above.
As you probably know, Nelson Pass was supposedly involved in the design.
