I heard a Marsh A400 and P2000t pre-amp over ProAc Response 1.5s, then same speakers using ARC gear (but for the life of me I don't remember which models). It doesn't really matter, believe me, Marsh aquitted itself beautifully. Now, this was at a dealership at less than ideal conditions (frankly, this dealership at the time could only demo 4 systems - they were moving and had compeletely depleted their stock & demos), but over the ProAcs, I thought it was a pretty even match. No doubt a longer demo would be more informative, but if you just wondered if Marsh is for real, it sure is. (not that it matters, but this wasn't even my audition - I was speaker shopping, and another couple was auditioning the Marsh stuff, and they allowed me to sit in so I could hear the ProAcs).
