I own the Mackie HR 824 monitors for more than a year now and I'm quite pleased with them - they are a bit noisy (rather high noise floor) and a bit slow in the bass, but generally speaking I like them a lot.
Now here comes this guy and offers me to trade his Dynaudios BM6A for my Mackies! What do you think? I will be able to audition, but briefly and in not so great conditions (the room is not that great for music listening...)
How do you like the Dynaudios?
