The best way to judge speakers is to hear them for yourself. Unlike Synths, Software etc, where it is easier to rate them, monitors are very much a personal preference. For example, many people seem to rave about Spirit absolute 2's and Yamaha MSP5's but I listened to them and though the spirits sounded bad and the Yamaha's were very poor.

Having said that, I haven't heard the events myself but I get the impression from magazines / newsgroups etc. that they're OK but you can do better. I wouldn't buy a pair just because they're on offer; buy some because they sound good and do what you want.

You might want to audition the Dynaudio BM5's, HHB Circle 5's, and Genelec 1029A. These are well worth the £ / $ if you're doing serious audio work.

Go for active monitors if one is available for your choice of speaker and you can afford the extra £ / $. In most cases the difference in price isn't much more than a decent stand-alone power amp and active monitors tend to sound better than their non-powered relatives.
