Yeah, it might work, question is if I want to be a guinea pig and how loud I will play. On the other hand, if I wouldn't play loud, then do I really need these speakers?
Do you use those 225 watts? I actually tried one time to max out my VSX 924's 105 W/channel in stereo mode with the current speakers, which are cheap but big, and measured the sound level with a dB meter to 110 dB! Somewhere around 90 dB I had to put on workshop ear protectors. And walking away to another room in the house, to listen to that maxed-out volume from a distance, I couldn't hear any sound distorsion. But then those speakers most likely have higher impedance (while definitely not being fine art in accurate sound reproduction).
I probably don't get anywhere near using the 225 watts, but I don't think that's the whole story. I have never had the volume knob to the half way point. 11:00 o'clock is very loud. What I have is a lot of headroom with the amp, so I am not pushing it. It also allows me the option of possibly buying bigger, less efficient speakers if a good opportunity arises. The combination of that amp and the Silver 8's are on a different level compared to my Yamaha rx-a1060/Klipsch RP setup in my living room. The Klipsch are very good for what they cost, and for HT, but in two channel music mode they don't have anything remotely close to the drive, impact and soundstage of the Anthem/Silver 8. If the two systems were compared in the same room, it would be not be a fair fight.
