Your Mac is 450wpc. What do you expect to be better with the Parasound? It would be a cold day in hell before I gave up any of my McIntosh for a Parasound. I had a Parasound Halo Integrated and compared to the McIntosh integrated I replaced it with, sounded like a cheap transistor radio. I would keep what you have if it were I.
Do my Dynaudio Evidence Temptations require more amp?
I have the Mcintosh 452 and was wondering if my speakers could be better served. Thanks in advance.
