It's like an other music EQ booster for treble and bass . Denon have 3 selections MODE 1,2, 3. I believe it a boost for music which lack or distortion in treble and bass. It works very well when listening with 2 ch music. I didn't know I always left it at HG (mode 3)on my Denon.

Denon's explanation of the "restorer"

GS951,

Glad to hear you are solving the problems with your system. So are you going to keep the XPA-2?

Wheelz thank you for the link and all others(GRUNT, GMEYER AND WID)that helped me trouble shoot these difficult issues-THE DISTORTION AND CLIPPING. I leaned a lot the past few days from you guys on this Axiom website. You guys are very good and helpful. Now it;s my decision to either return or keep the EMO amp. Good amp and excellent price.

Gmeyer...I love the sound of the EMO amp with Axiom M80. It is very hard to say RETURN at this point. But, the truth is that I don't have shutdown problem anymore and know how to work around my Denon adjustment. Denon will be good service in my HT room for now until I receive my new EMO pre/pro UMC 1.

Glad it's working for you now. I'd say keep the amp--it does seem to be working now, no? And like you said, it's an excellent price. Congrats!

It's good to hear the system is working well.

Yes. Right now, it's working beautifully at this point. I picked out my BR movie, "U571" very extreme DTS-HD sound and half way into the movie. NO problem. The sound is so amazing with these AXIOM Speakers. The highest I recorded on my SPL meter is 107dB (with bomb, depth charge, gun fire, and ship explosion). SQ is dynamic loud!

Glad to hear you have your settings corrected and it helped your situation. Just out of curiosity what is your main music transport, CD or ripped music? The restorer function should only be used with ripped music as you have found out thanks to Cam's link.

Just goes to show how critical the avr settings are and how, when set incorrectly, can screw things up and the amp gets blamed.

There, fixed it for you Jay.
