McIntosh -- good for show, not for sound, says dealer

This is either my first or second post here. Mostly, I just read but since I’ve got two vintage Mac amps, I decided to chime in. One has autoformers and one is direct coupled. I front one with a Mac preamp. The other with a Rotel preamp. Nothing sounds veiled to me. I truly don’t get where that comes from. As a matter of fact, the direct coupled MC2002 is quite lively. My MC2155 is smooth and warm and I anything but veiled. Speaker choice can make anything sound veiled or lively.
