I have the Marantz SR4600 running M22ti, to my ears I like it more than the HK3480 and NAD C352 that I just sold. In comparison and to my ears...the HK3480 sounded dull, the NAD C352 lack punch and a bit too warm for my taste. This Marantz reminds me of the Odyssey Stratos that I had few years ago.
