Hi There,
Seeing that the Yorkvilles are made just up the road from where I live (Toronto) I've had the opportunity to check 'em out, along side the other, better known monitors.....in fact, I've been thinking myself to get a pair of the active YSM-1P's (115W per side) which sound really good "for the money"
They retail for $740 Cdn ($450 USD) which is good value, coz let's face it...there aren't very many decent choices in the under $1000 Cdn ($800 USD) price range.
Last week I listened to them for over an hour at a local music store, and I was quite surprised at the sound quality....I couldn't really tell any difference between them and the Tannoy's which cost almost $400 more...or the Event 20/20's with my eyes shut...
Yeah, the Mackies, Genelec & other high priced monitors DO of course sound better than the Yorkies....BUT, certainly not as much as their 2-3 times price tags might suggest.
I haven't been able to hear the Behringer Truth's yet to compare them (simply coz they are totally out of stock in North America at the moment)....but I hear that they are "great value for the money" also....
Like the other poster said - I don't think your'll find a better sound than the Yorkvilles at $450 USD.....
I also checked out the new M-Audo SP-5B's too....they are rather small....sound OK....but not that great....
Just my 5 cents worth here
