I get the model numbers mixed up. I have the 125w version 52 or 5300. If you are looking at the 125w version $499. is not such a good price. This amp is a couple years old and MSRP was only $699. If it's the 220w version you had better jump on it. That's a good buy. The 220w version has more output devices and sold for over $1k. You would still be hard pressed to find a better 125w amp at $499. I use mine on a second system to drive some Dynaudio 62's. My impression is these amps have a bass hump that is nice if you are into Rock and Pop. They tend to get grainy long before they should when turning up to high volumes. My Adcom don't have any problem driving my 4 ohm Dyns. I don't find this a particular strong 125w as far as remaining clean power. I wish you would have told us what other gear you have.
