Polk Audio RTiA9 with amp?

[BobbyMcGee]

I own the RTiA9 tower speakers and power them with my Emotiva XPA3 Gen3. I also use the Emotiva for my CSiA6 center channel speaker.

I have noticed the A9's open up more using the Emotiva than my Marantz AVR. They sound a bit muted with the AVR.

I also recommend higher quality speaker wires. I use Audioquest cables for my system. I noticed increased clarity when I upgraded to Audioquest cables. For the A9's and CSiA6 I use Audioquest Type 4 cables. And, for the Emotiva to the AVR I use Audioquest Greyhound cables.

Finally, I recommend a decent quality power conditioner and decent quality power cables. Again, I noticed an increase in sound quality after upgrading. I use Pangea power cables, AC-9 for my Emotiva and Marantz. And, AC-14 for my Oppo.

With that said, I am waiting for a good sale to upgrade to the Polk LSiM series speakers. The A9's are very good but I want to see and hear what the 707's have to offer.
