The older parts of this were put together gradually and then a flurry of upgrades led to this final, wonderful sounding incarnation. I also use a tuner, cassette, DAT, occassionally lp's with an old B&O turntable and some synthesizers through a mixer. However for real music listening this system with plain old redbook CDs is far closer to being in the concert hall than I ever thought to get at home. I am quite new to anything this high-end (in my own system anyway) so comments and suggestions would be very welcome.
I'd go along with the addition of sub (s), one or two. My favorite is the M&K 105 at about $1200ea, but they're big and ugly. A friend has recently installed an M&K with his MgIIIs. A key feature here: He used cap filters on the interconnects, so that freqs from 50Hz down dont get to the amp. The amp doesnt have to pump out big power for low bass notes and the Maggies dont have to flex for big slam. The sub is crossed over at 50Hz, and fills in the bottom without bloat. This is a trick I thought was limited to car stereos, but works well in a very high end set up. Resulting sound is louder, cleaner, faster and full range.
