Bryston 7B-SST

The Bryston 7B SST mono amps are a must for anyone with challenging speakers (such as my 4 ohm Martin Logans) or a desire for pure accurate sound reproduction. They will drive virtually any speaker you throw at them. Your bass will be extended, your mid-range clear and accurate and your high's with float with the angels effortlessly.   From a review by Dwayne Carter, Enjoy the Music.
