I installed a few 2600's and like I have said else where they never failed me in commercial or professional service. The very few home owners never had issues either. Lets see, large Magnepans with 85 db efficiency would benefit greatly from 2600's. KLH 9's, too. XR 290's were tested with 2600's wired for mono and people used them with MC 1000's. MY XRT 28's are rated at 1200 watts but thats more of a music power rating and MC 2600's and MC 602's would be a great choice. I prefer the mono MC 830's that measure about 580 watts continuous each into the 4 ohms which my speakers are in fact. As I am an old man I can lift them one at a time. I could never lift a 2300, 2500, 2600, 602, 601, 611, 1201, 1.2k or 1.25k or the new or old 3500's. So Mcintosh, thank you for producing the MC 830. I did lift the early 3500's by myself when in my 20's, but from then on it was two Strong people to lift those light weight amplifiers. Mcintosh was like Ampex professional. Throw a product in a portable carrying case with handles

I wish I had had that blue portable case for my 4 channel Ampex. You could store tape under the tape transport very easily.
