what would you do?

@labguy If you can swing the panels (the low cost ones I have are not very attractive) they make a world of difference. Prior to the acoustic treatments, I used to try and play the Smashing Pumpkins Siamese Dream in my room and it was physically painful. After the treatments I could play that disk rather loud without issues. The sound was also cleaned up in all the best possible ways.

I was actually suggesting the Anthem STR preamp and not the integrated. However, I now see you are using an integrated. 

Suggestions: 1. Stuff some socks into the ports to reduce bass. 2. As these speakers are bi-wire, remove the wires for the bass speakers and just use the mid-tweet. 3. Bi-amp with a nice integrated (like new Parasound) on the woofers. Doing this lets you trim/boost bass at your discretion (it's good to be the King). 4. Trade them in for some B&W 805 two-way stand mounts with a small subwoofer (B&W DB3D). Just don't accept a huge loss on your investment.

Maybe you can exchange them for the f206? The bass from the f208 is in my opinion their weak point. As with most stand-amounts that tries to play full-range with small woofers. The Spendor D7 gets a lot of praise on the Audiogon.

Thanks for the suggestions. I paid about 2,800 for the speakers 6 months ago.  I'm getting offered 2250, so it's not a huge loss but even if I sold everything off that I owned and started from scratch I'm not sure that I could got a better system for only three or four grand.

I had a similar experience with Revel F36s - different speaker model but they're actually quite similar. My local Revel dealer admitted that they upgraded the Performa line to the Be models because the new Concerta series is too close in performance to the F208/206.

 Anyhow, I found the bass was overpowering, even in my largish room (15.5 x 26'). I also noticed the somewhat clinical midrange character - some music was stripped of its soul. Revel support told me it's safe to plug the ports - they recommended 3" deep foam. Unfortunately the bass was still difficult to enjoy. 

As for room treatments, there's not much you can do in a small room to tame the bass. The Revel 208s have an elevated frequency response in the upper bass, near 100Hz. Bass traps would have to be  very large to alleviate that region and they'd be totally impractical. Wall treatments that absorb mid and high freqs can actually worsen the clinical character.  

I recommend finding a pre-owned or demo pair of Spendor A4s - can probably be had for ~$2500. All the detail and imaging anyone should need while preserving the music's verve.
