I've heard them - once, for a half hour demo session in a shop whilst selecting an amp to go with my Epos Epic 2 standmounts (which the shop didn't have in stock at the time, hence went with the Epic 5 as a compromise). So I've heard them on the end of an Audiolab 8200CD and either an Audiolab 8200A or Creek Evo 2. Difficult to make a direct comparison with my Epic 2 in their normal environment but from memory they shared similar characteristics, which basically means I liked them a lot. Really lovely, natural sound and revealing mid range, with vocals particularly impressive. On the odd occasion that the sales guy was hiking up the volume way beyond that which I'd normally listen, they seemed very happy to pump out good, punchy bass but still clear, detailed, realistic mid/high, with grand piano in particular sounding about as concert-like as I've experienced - not that I've experienced anything much of the "high-end" variety, but to my ears it sounded impressive!
