"I should preface this review with exactly who

the listeners are: Robyn - USACi sound quality

World Champion and me - both musicians and

audiophiles. Needless to say, We are a tough

bunch to impress. The overall transparency is

crystal clear, giving us the sonic illusion that the

musicians were performing over the engine. I really

can't express how happy we are with this set

- and every other Critical MASS product we've

had the pleasure of listening to!" USACi sound quality World Champion
