Could you please go into a little more detail about the sound. Was it slow or fast? Deep bass? Warm or neutral? Big soundstage? Thank you.
With the big caveat that this was at a CanJam demo and with show conditions.. The EVO was setup at Upscale's desk with the Utopia, and I hustled to borrow an AC from another booth to hook up to it as I was curious about the combo and had a hunch. The TLDR is that it sounded like a classic OTL: clear, sweet, and resonant. Very pleasing dose of second order harmonics (or at least what I imagined to be) with a 3D soundstage. It was very cealn well resolving while being sweet and euphonic.
If I didn't get the new Decware/ZMF Reference OTL (which I can't recommend enough), then this would have been my next choice without a doubt.
