I ripped the demo CD into my server. I can change the speakers within 2 seconds between Phil3 & KEF or Phil3 & Salon2. I can change within 6 seconds between Phil3 & Orion. All volume matched per SPL meter, of course (all channel levels @ 75dBC).
I now have the Denon's/speakers configured:
Xoom tablet controls:
Denon 3310 - Orion3
Denon 990 - Phil3
Sony S tablet controls:
Denon AVP - KEF
Denon 5308 - Salon2
And if this were an exam, I would flunk because I'm having trouble telling much of a difference in the trebles & midrange for the last 60 minutes. Since it's not blinded, I can remind myself the difference. But honestly, I cannot tell. Perhaps the difference is just not significant enough for my to differentiate.
I don't know if that's good or bad. But since I can't tell the difference between a $22,000 Salon2 that has been declared Speakers of the Year by numerous critics, I think that's good regarding the Phil3.
I'm still listening to the demo disc. The Phil3 is quite punchy on the bass. I mean the bass is more powerful than I realized.
