Well, matter of factly, the lowest wattage of all is the MA-2275, which I own. What's your posion?? SS or tube?? You know my way of thinking by what I own. If you like SS and don't need alot of power and is cheaper, would be the MA6300. There are some features not found on the MA6300 though. No tone controls, no record monitor, lower wattage and would you like LED or bulbs with that amp? Does that matter or carry any decision weight? The MA6500 at 20 watts more has bass and treble controls, and the MA6900 with it's 200 watts, has a 5 band equalizer? Would you be interested in tweaking the sound of your unit and enjoy the so-called, tube sound? Then the fiber optic lit MA2275 with tone controls, tone bypass switches along with a record monitor switch, may be what you're after. As`far as an older model goes, there are better discontinued SS versions, BUT, McIntosh has never built a better tube integrated than the MA-2275.
