I've always had McIntosh tube amps in the house. I've tried the M80s with mc240, mc275 and mc2102 amps. All of them had a different sound quality with the m80s. The mc240s at only 40wps were very satisfying at moderate levels but ran out of gas with loud classical or rock music passages. The mc2102s at 100wps had a more nuanced presentation but didn't have the solid tighter bottom end of the mc275 at 75wps with its higher damping factor.
I grew up in a house with a solid state McIntosh while my uncle had a McIntosh tube amp. It was always amusing to see my dad and uncle argue about whos was better.
