You are right when you say of the other amps that none was better than the Emotiva, given that Emotiva amps are well designed.
Emotiva amps do not 'cause' sibilance. End of. If someone has sibilance in his system it means that a frequency band of 5-6 KHz is being emphasised for some reason (I am assuming tweeters are not broken etc). If you look at the FR plots for the Emo amps there is no such emphasis, so the Emo amps simply cannot be responsible for it. Anyone suffering from this problem needs to look elsewhere to find the source of the sibilance and fix it. Also some people are especially sensitive to sibilance and 'go looking' for it. Sometimes there is natural sibilance on a voice and that needs to be considered too. But whatever causes it, it ain't the Emos.
You later posted that you were in fact not 'bent out of shape' as I mentioned, I would just say that when a person types that they are fed up with repeating themselves it means that they are unhappy about it, so I am glad to hear that this did not upset you after all.
At any rate, as I just responded to another poster, no one is saying that the Emotiva amps are defective or cause sibilance. It is the recorded music coupled with a bright speaker that causes it. At least that's what I found in my 2 channel system which included an Emotiva amp, the XPA-3. I read up on the issue about 8 months ago when I first noticed it, and realized that my Paradigm Signature speakers, while being very defining and resolving, with some tracks of music I was getting sibilance. I did not have the option of EQing it out, and I didn't want to replace the $6000 speakers and keep the $600 amp, since the speakers are otherwise so amazing. But none the less, I had a problem.
Further reading, which would be heresy around here, was that some amps had a warmer sound and would aid this. On other forums they suggested Anthem amps to me as they are the sister company to Paradigm, but I had a bad experience with one of their preamps, so I was reluctant to give them another shot, plus Anthem higher end amps run into several thousand dollars. Some suggested tube amps, which also have a warmer sound. But I read about Parasound amps and thought this would be the answer. I bought a A21 amp, 250 wpc, and when I hooked it up and ran it side by side with the Emotiva amp using the same tracks and the same system at the same volume( measured with a sound level meter) the sibilance was gone with the Parasound amp. Some may want to take issue with this, and that is fine, I share it here for those who may be experiencing this and looking for solutions as I was.
So when this thread on the Emotiva forum came up I read with interest because I had been there, and it is not a fun place to be when your system is having problems. I'll leave it there, I'm not trying to stir the pot or anything, I just thought some might be struggling with the same issue I had.
