Suggested Improvements for Set Up?

I just wanted to update everyone on an amazing upgrade to my system. I just added the new Emotiva XPA-2 Gen Amp to my set up. Wow this amp really made the 707's come alive! The difference in sound between the XPA-2 Gen 2 and RX A3020 is remarkable. The 707's produce so much more detail and bass now that they are appropriately powered. Made me fall in love with the speakers again! Thanks for your help!

In the low-cost / high-impact category, even though it wasn't on topic - take a look at the room. I've done some minimal, visually non-intrusive treatment that tamed some high-end harshness and really opened up the music.

Congrats on the amp and the improvement - now take a quick look at the room to really bring out the last bit of detail and control your amp/speaker is capable of.

I was going to suggest the amp. I have the earlier AVR, the 3010. I used that and an old Yamaha amp at 150wpc to drive my speakers. I switched between them and didn't really hear much difference. Through a recommendation from a 'goner, I upgraded my amp - to a used one from here, different member though. Unbelievable difference!!! The quantity and quality of bass means I don't use my sub for 2 channel, and the imaging and details improved greatly. My room isn't 'tuned' or treated and is very live, but I can totally relate to the improvement you noticed. I bet I put off the upgrade-speakers bug for at least 6 months:) I have lots of work ahead of me to get the most out of what I have, and there will be upgrades, but that one change was huge for me.
Beaverlake, what sort of room changes have you done? My room needs work, but since it's the family room as well, I don't have a free license to do anything.
