The resolution is the same in sub and satellite filters, so any degradation to performance with an XO could be from 1) Not a good Audyssey run on the sub. Was the sub loud enough? Did you use all 8 positions? 2) The mains are in a more bass-friendly place than the sub. Audyssey can only do so much.

If I XO at 80hz I observe a degradation in performance, but this is because my room has a resonance at 80hz with the sub in it's current location. If I XO at 40hz, it sounds much better. Try a lower XO?

this is not correct at all, all audio stuff are designed with a target customers in mind and if you sonically you are testing the dac's in both equipments the classe "to my ears" is more accurate because of this I bought it. many user will buy stuff that not needing for example I not need more then 5,1 channels processor so DTS X or dolby atmos never will be in my list, I was looking for better performance in concerts and movies and I found it with the AV8801 and a 50% of the retail price is a bargain.

if you are looking to exceed audio performance and "musicality" I don't think that you will get it with the 8802 but with a SSP-800 or high end processor you will be. if you want a good audio performance with multiples options, room correction, dolby atmos and 13.2 channel handling so the answer is easy "8802".

BTW classe CP800 have magnificent performance with technical aspects and I hear a small hiss if I put my ear 1" from my tweeter and to 1 feet I couldn't. when I did the same test with the AV8801 in my center and surround speaker the hiss is even lower than my front speakers(I bypass the CP800 when I listen multichannel content). maybe I'm wrong but low hiss noise is not a accurate measure of quality of equipment.

thanks for your answer.

The resolution is the same in sub and satellite filters, so any degradation to performance with an XO could be from 1) Not a good Audyssey run on the sub. Was the sub loud enough? Yes it was 76 dB according to marantz guide Did you use all 8 positions? Yes I did, even I put the mic’s in the same position that the marantz assistant required 2) The mains are in a more bass-friendly place than the sub. Audyssey can only do so much. I guess so, I planned my setup for two channels content mainly so I think that room acoustic I put in my room are helping this.

If I XO at 80hz I observe a degradation in performance, but this is because my room has a resonance at 80hz with the sub in it's current location. If I XO at 40hz, it sounds much better. Try a lower XO? Ok I will do.

BTW I have another doubt, finally I could use the XLR output to center and surround speaker and run again audyssey and I was surprised that the level set for it in this speaker was lower than before, for my center with rca cables was -3 dB and now with xlr is -1dB and the same thing happened with my surround, if the xlr have a gain of about 6dB why Audyssey set it with more gain that before?
After my last Audyssey reconfiguration the sub was taken of my system, not sound are coming from it, I think this room correction are not ok.


the XLR cables are musically II straightwire and for my fronts are kingcobra audioquest, in my fronts it was set to the level of -7.5 dB and during the audyssey configuration was way louder than my center and surround.

This suggests to me that you have not read the Audyssey 101 and FAQ. The instructions in the equipment manufacturers' owners' manuals are woefully inadequate and often misleading (as for the microphone positions). The Audyssey 101 document here on AVS will help you to get a better calibration.

The actual gain difference depends on the implementation of the two types of connections in your amps. Different designs have different gains.

Check the subwoofer channel's trim level in the receiver. If it's "too low", the signal getting to the subwoofer might not be high enough to trigger the sub's auto-on feature. i.e. turn down the gain on the subwoofer itself so that the 8801 will turn up its output signal. Also, you'll have to manually change the settings for your front speakers from "Large" to "Small" in order to enable bass management with low frequencies redirected to the subwoofer. (This is all explained in the Audyssey FAQ.)

anyone with a 8801 willing to dump there prepro now to get a 8802 or 7702 is going to be really pissed off in about 2 yrs because once all the other competitors come out with there new codecs and,
If you do want 4k content, every device in your video chain must have HDCP 2.2.
HDCP stands for High-bandwidth Digital Content Protection. time to chill out and let these companies get there act together.
