I see the McIntosh haters are out in full force tonight. I have 2 Mac systems and very seldom have to use the tone controls but if the recording needs a boost then I use them. I have never heard dull or shrill sound from my systems. I had a couple of guys over 2 weeks ago, one of them is an Audiogoner and both loved my 2 systems. My Audiogon friend has Pass Electronics and Magnepan 3.7i and VPI table. He loved the sound of my system, and no, he wasn't being polite.
Don't diss Mac because of a bad demo. It is well made, lifetime lasting, excellent sounding equipment. Everyone here may not like the brand, but they sell a lot and I am glad I bought from a big company who can take care of my equipment for years to come. A distant friend just had them make a new glass front for his 1971 tuner. How many other companies can or will do that?
