The price of these active monitors recently dropped from $799 to $349. I've had my eye on them for some time as an upgrade to a pair of M-Audio BX5a monitors for one of my workstations; and decided that the price drop was reason enough to finally pull the trigger. There is not enough room behind the workstation for even a bookshelf speaker, so monitors have had to be the way to go. Note that these won't work with a stereo receiver or AVR that lacks a pre-out; and, even then, you will need some means for controling the volume. I'm using mine with a headphone amp that has pre-outs in addition to the headphone jack.
These suckers are big . . . really big. If you don't have a large desk or don't have a pair of beefy speaker stands, then this is too much speaker for you. Here is a shot of a BX5a perched on top of a Prodipe Ribbon 8.
The back of the speaker:
As you can see, inputs include an unbalanced RCA plug (for consumer equipment) and balanced XLR or 1/4" TRS plugs for pro gear.
I'll post a review on gdgt.com in a few weeks when I get some more time with these speakers.
