Wow, what a great deal, Alvaro, congrats.
Now, I´m thinking your Rogers LS-55 ST´s could use that for the tweeters, the power amp section of your NAD for the woofers, both driven by the BK Electronic crossover you have.
I´d say you´re on your way to "The Active Way"
Jorge.
P.S. - If you can get another one of those for something like that price, please buy it for me. Up to 3 times that price is still a good deal for me.
