Got one. Bought it off Ebay a couple of months ago. Spent a little more on it than your seller was asking, but it was near mint and from a trusted seller nearby my home.
So far it has been excellent. The sonic character is a little laid back for an amp capable of 220 continuous watts with +3db peaks and stable with 4-ohm loads. The bass is very good with deep, strong, extended tone. The mids and highs are also excellent.
Whether you will love the amp or not depends on a lot of different factors. The type of music you like to listen to, the speakers you favor, the dimensions of your listening room, etc....
Personally I favor a faster amp. I started my vintage audio addiction with mid to late 70's Sansui integrated amps. These are much faster, with an attack to the sound that would be hard to describe. So far I have Sansui’s AU-717, AU-9900, AU-9500 and others. All of these have a totally different character than the Kenwood, and a sound that I prefer.
That said the Kenwood is an excellent piece. It's so strong I haven’t yet fully cranked it. Currently I have JBL towers hooked up that will leave your ears ringing if care to listen that loud. And I like it loud.
The M2A has been described as one of the all time great bass amps. Some people buy them just to power passive subwoofers. With a damping factor of greater than 1000, it should be.
I would see if the seller would allow you to preview the amp at your house to see if this "flavor" of amp is synergistic with your system.
