Hi im no expert and very new to sound and vision. So here goes my BEST demo room was spendor. they were simply brilliant to my taste in sound . A big airy sound feild that sounded so realistic the band were playing in the room. My WORST demo room was the Onkyo demo room with Monitor audio RX range. They had some concert/band playing, the sound was a load of muffled bass banging away with no clarity no detail the combination was easily by far the worst room . I have the RX RANGE with a yamaha receiver and was really excited about what my speakers could do with a really good amp ,cable setup. It was a shambles . My living room any day over that @$%@. Short and sweet im am not good with reviews but this is my opinon P.S 3d tv was kack a load of flickering fuzzy-head nonsence which isnt ready.
