Thanks for your responses!
Believe it or not, I haven't listened to the amp yet. Not living near a high end audio store, forces (?) me to begin my search via the internet and magazines. So I planned on reading some reviews, picking some prospects, and then going to the nearest retailer of that product. If anyone has a better (or different) approach, I'm all ears. I plan on spending a fair amount of money* on a system and I'd like to get the best possible bang for my buck ... if possible.
Oh, and I thought I'd be clever and call Nuforce and ask them what speakers they test their amps with ... I had forgotten that they also make speakers ... silly me
* at least to me it's a fair amount
