Depending on where you bought the amp, why not ask if they have some ex demo speakers for sale, failing that, see how you get on with your Kef's, they may well be up to the task. I cant answer your question about the DM1's but on paper they look good as do the EB1'S but i would rather audition any speaker in a dealers room with my amp, i know it's not the same as in your home and the 30 day money back guarantee is tempting but if you dont like them you have the added expense of sending them back, i have heard the Monitor Audio BR 2's with a Rega amp and liked them a lot although i have not heard the newer versions.
