Audyssey Speaker Levels Issue

Seriously, I have no life.
Those who use Marantz AVRs, or Denon's obviously with the XPA gen3 are likely the majority so they would have no issues and those using the Marantz AVP may not all use XLR, I would guess 50/50, so you will see why most users won't have this issue.

A quick search found that those who use similar combinations do have the same issues. There must be more if you search harder:

Marantz AV7702 MKII to XPA-7. Input Gains. | The Emotiva Lounge (proboards.com)

I would agree with TLGGuy partially that it is an Emotiva issue, only partially because they haven't really done anything wrong except they should have provided some flexibility, if not variable, at least something like a selector switch (hi/lo selection).

The main reason for such kind of issue has more to do with your speaker's sensitivity and your seating distance. The BP7001's sensitivity was listed 92 dB (that's vague without stating /w or /2.83V, anechoic or in room) but it could well be 95 dB or more in your room, and the way you connect them as they have powered subs.

So to be fair, the Emotiva is not to blame, strictly speaking. As @lovinthehd alluded to earlier, you do have another simple solution if you want to go back to XLRs, by using a spl meter and adjust all channels to the same level. I don't like that simple solution because then you have to record what you have adjusted to each channel and allow for that in your head when you adjust the volume dial. That may not be an issue for most people who just do it once and are happy to forget and enjoy. It is for me, as I do enjoy playing around with REW and the Audyssey Editor App.:D You cannot do such manual adjustment and the re-run Audyssey, or more precisely, you can, but then Audyssey would set all channels back to -12.:D

Consider yourself lucky too, that switching to RCA is enough to do the trick, if you had certain Klipsch models, RCA outputs lower voltage may not be low enough.:)
That really is the point, as in domestic installations there is no advantage whatsoever to using a balanced over an unbalanced connection, so this is really a non issue.
I do maintain though that if you put an XLR connector on the back if a piece of equipment it should conform to prevailing professional practice or be able to conform. Not doing so will cause problems as it has in this case.

I think that you will find that most people with external power amps are using receiver preouts as the front end. These are all unbalanced connections. In addition I suspect that people who do use pre/pros probably use more upscale power amps than Emotiva. Emotiva is certainly not in the top flight of equipment manufacturers by a long shot. I have three Marantz pre/pros in use and one in storage. I have to say they have been good performers. The ones in use are two 7701s and my 7705. I have done my own measurements on those and they conform to International standards for balanced and unbalanced outputs.

Yes you would think putting XLR connectors along with RCA on any Home Theatre device AVR/PrePro/Muti Channel amplifier it would go into increasing the price of the unit. So those connectors probably are not free

Thought about the sensitivity of the BP7001 with the powered subs but I also have DefTecs BPX for surrounds. 90db and UIWRCS111 92db for In Ceiling speakers. Vaulted Ceiling No subs in those they also came up -12.0 on Audyssey

Short distance could be part of the reason too.
