Yep, keeping them both, at least for now. I may sell the 600 privately once the 800 arrives, but I've at least decided at this point not to do the trade-up program. (the owner's club discount was too good a deal to pass up)

Though of course, there's always the option of trading up the 600 to another 800. \:D

Yeah, Sean; there's been some discussion of this "bomb"(probably a bit of the exaggeration typical in audio)on some of the boards for maybe 8 months. The previous replies have covered it pretty well, but as to whether this relates to Sat's issue, there appear to be three common factors necessary and it isn't clear at this point if they all apply to his case: Blu-ray; DTS-MA; player sending bitstream(not PCM)to receiver for decoding.

I haven't heard issues with clapping or ocean noises, I used U571 for ocean noises and parts of LOTR - FOTR for various clapping noises also listened more closely to Eagles Farewell tour in DTS and they sound great to me. I am suspecting you may have a bad 663, maybe time left for some warranty or exchange for another make?

So we re-ran Dark Knight last night (the girls just had to see it, I was the only interested party on Xmas) and it clearly was the left M80 (mostly) that had the popping sounds, I replaced the speaker cable and RCA interconnect to no avail. Switched the Yammie settings to "small" for the M80s and crossover to "40 Hz" ("60 Hz" sounded like crap without a sub) which resulted in an amazing improvement; lost the deep, teaser "wannabe" LFEs but also lost the major popping sounds on this program material and gained an incredible improvement in the integration of the center, M80s, and surrounds (no more cheesy "Oooo" wind or other formerly ridiculous e.g. HF "audience clapping" sound effects); no joke, the surround effects really sound great now, I suppose that's no surprise but it's news to me, whew the qs8s actually perform as advertised, still waiting for the 800 . . .

Sat - the saga continues! Do you have a laptop you can use to run test tones through the M80s? If so, you might want to run a signal sweep through the system using a free program like REW to see where (at what frequencies) the M80s start to crackle.

This might help you pinpoint where the problem occurs, test different surround modes on the receiver, test speakers individually, etc.

SatK, I really think you should be looking for another avr to use a pre when you get the EP800 or theA1400, I think you will still be having issues. All that popping/clipping(?) in the LFE can't be good for the subs amp either.

This is my first post....I apologize as I haven't read the entire post. I saw the post about crackling noise in the Dark Knight. I had the same exact noise at the exact same point in the movie, except I have the M60v2's (less than 30 days) being driven by a temporary Denon receiver. I was waiting on the Emotiva UMC-1 and MPS-2.

I have been looking to see if anybody else heard the same thing in the soundtrack. Different system, different speakers...maybe this is part of the soundtrack or an error in the decoding?

I may have to check out that part of the movie on my setup again. The first time I watched the movie I didn't notice anything, and I'm usually picky. \:\)

I listened to it again today and I think it may be part of the soundtrack. It is odd, because there are other events with much more low end thump and this sound is not present. I hear it coming more from the left speaker more than the right. It is also in the center channel (VP150) a little as well. It seems to be coming from the tweeters. It occurs toward the end of the wall crumbling and I think it may be the representation of the crumbled wall hitting the ground. If this is the case it is a poor representation as it sounds more like sizzle and cracking than debris hitting the ground.

Has anybody else experienced this sound in their Axioms while playing back the Dark Knight Blu-Ray?
