For 'philes on a moderate budget, I always recommend Paradigm and PSB speakers as a great starting point. I think their cost-to-performance ratio is excellent. You might also want to consider some of the lower-priced B&W models, such as the 603, and used Vandersteen 2Ce's can often be found for around $700.
Looking for speaker suggestions
I just picked up a C372 integrated amp by NAD and I am in question on what kind of floorstanding speakers I should get. I'm looking to get a set thats sounds good, but will only run about 750 - 800 for the set. I had someone suggest the BETA 50's by infinity. My primary concern is sound quality. Any suggestions?
