Any chance you can borrow /audition these amps with your speakers? I find it much easier to decide when it boils down to just 2 amps which one to buy. Also keep in mind that even if you buy much more expensive amplifier, The speakers playing the setup in 'Your' room will sound different in some other room. Also placement makes or kills the entire setup, and don't forget the source. The better the source, better the chances of you falling in love with the sound. I think both amps are capable of driving your speakers with ease, so a testing it with your speakers would be the ultimate key to make a final decision. Good luck.
