I'll go out on a limb and say I prefer some reconding on a much lesser system. A lot of Led Zep comes to mind. I find my very good system tends to highlight just how poor a lot of these recording were. I save them for my car.
Can a great system make a mediocre recording sound good?
I spend a lot of time searching for well produced recordings as they (of course) sound so good on my system (Hegel 160 + Linn Majik 140 speakers). I can't tolerate poor sounding recordings - regardless of the quality of the performance itself. I was at a high end audio store yesterday and the sales person took the position that a really high-end system can make even mediocre recordings sound good. Agree?
