Don't get me wrong..I wash trashing Bose, not McIntosh. The first time I heard McIntosh was in 1970. Went to a Christmas dinner on the Olympic Peninsula in Washington. The host had a MAC tube receiver in his living room hooked up to a pair of floor speaker's. Sound was excellent. The one company that gave MAC a run for their money was Fisher. Their tube receiver's from the 60's were outstanding. I trash Bose and will always remember when Amar Bose sued High Fidelity Magazine in Superior Court in New York in 1968 for a very negative review of his 901 speakers that just came out. He lost.
