I have been researching receivers for about a month and know a lot about what features you can get at various price levels. I have focused a lot on Denon, Onkyo, Yamaha and a bit on Kenwood. But recently I started looking at Marantz. Their receivers seem to offer the best feature/price ratio out there besides the Kenwood models. The 6200 model is a 6 channel receiver with PLII and preouts on all channels for a street of about $485. And the Marantz units all seem to have high weight and good build quality. My concern is I read reviews like at audioreview.com and everyone said the sound is great but people complain about a popping sound when the mute circuit is engaged, e.g. between tracks. How big a concern is this? Who out there owns one and would care to comment about it?
