I owned a Marantz 2230 and it was nice. I liked the flywheel tuner the best. But when I replaced it with a NAD 3140 my large Advents really came to life. It was no contest.
Magical Marantz 22## receivers
Why is it generally accepted that caps in a vintage speaker crossover should be replaced but some how these mid-fi (at best) 70’s vintage receivers seem to get better (and more expensive) with no maintenance. I would love to see someone bench test one of these beauties with the “tube like” sound.
