The Karan Acoustics KA M 650 monoblocks are amazing amplifiers. They have near limitless power, 650 watts into 8 ohms and 950 watts into 4 ohms and run fully balanced. More than just power, they have the amazing Karan Acoustics sound. The bass in particular is exceptional and they wonderfully musical. We have used these on everything including Avantgarde Duo Omegas (I know silly overkill but astounding to hear musicality), and they are stunning. The amps are built like tanks, and at 110 pounds, weigh like them too. About the only thing that sounds better are the amazing KA M 1200's and 2000's. We are the North American Distributor for Karan Acoustics and these amplifiers have only been used on a few occasions for demo purposes. They are in excellent shape and come with full warranty and are absolutely not grey market. Read the terrific review they got from Roy Gregory
The KA M 650's have been replaced with the even more amazing KA M 900's so these need to go. The new price was over 30,000 dollars. These can be had for 20,000. They come in their own wooden cases. I would be happy to chat with you about them, if you drop me a note. Low ballers will be ignored but reasonable offers are considered. The amps are difficult to photograph but here is one photo and stock pictures. Thanks for looking.
