Depending on your source, you may want to look at powered speakers, this would have the amp built in and optimized for the speakers. You could look at Audio Engine, Vanatu, I heard a set of outstanding powered speakers by Sauk for around $2500.00, or from there you could look at Dynaudio. With streaming becoming so popular the powered speakers, with most having a DAC built in as well, have also become popular. (DAC = digital to analog converter) Considering this is basically the entire system pricing isn't so bad, but does cover a wide range depending on budget.
