I heard some crazy Grand slams or something from them in like a 70,000 dollar system and did not get it at all,,, I have heard 8,000 speakers that would smoke them... but some guys love Super pinpoint accurate flat sound, not necessarily musical sound that we are looking for, so I think that is the market that wilson is in, but again I'm sure someone will argue You need to have 20,000 dollar amps or just the absolute correct system synergy to make them go, but even then I would go about 1/4 the cost with other stuff and be quite happy.
