However, the DC-300 does not produce the cleanest sounding midrange you could get, it DOES produce great sounding bass, though. I have heard the Adcom 555 MANY times, it was never one of my favorites, others love it, though. Marantz amps, they are prized for their particular sonic character, as you can see on ebay auctions and what vintage Marantz amps go for. This is an area you have to decide for yourself what you like best, there is no right or wrong, just what YOU like listening to.
