I am planning to purchase either the MA252 or MA5300 / MA7200 for a 2 channel system to power a set of Klipsch Cornwall speakers. I would like to connect the McIntosh MT5 turntable, a Bluesound Node 2, and my TV / cable box to the amplifier as well. We listen to classic rock, folk, some country, a little modern pop. Is there a compelling reason to pick the MA252 over the MA5300? Is the MA7200 overkill for the Cornwalls? Appreciate any insights / advice.
