If you want that "big buck sound" for under 50k, I believe you would be wise to look into the Grandinote Mach 9's. They list for around 42k, and they are a wonder. I own their big brother, the Mach 36's, which retail for around 150k, and although the 9's aren't quite up to the 36's in terms of sheer magnitude, they have very similar characteristics, especially when it comes to the sound-stage and neutral coloration. I know these are not well known in the states (they're manufactured in Italy), but if anyone here is in the NY area and would like to hear the 36's, I would welcome you to come over to my house for a listen, perhaps embellished with a fine dram of single malt.
By the way, the Mach 4's, which run about 25k, are also an amazing speaker, especially in a smaller room.
