Any of you technical guys see any issues with pairing the Spectral pre with the Pass amps ?
First, let me add my sincere best wishes to the thoughts others have expressed about the challenges you are facing.
After looking at the specs and descriptions of the Spectral 30SV, and being familiar with the Pass XA amps, I don’t see any technical concerns that pairing would raise. Also, see the writeup on Spectral near the bottom of this page:
http://www.goodwinshighend.com/amp.htm
As you’ll see, the note therein begins with a statement that:
Whereas other Spectral Audio components (i.e. their preamplifiers and digital source components) may be used with any other brand of equipment, Spectral mandates that their non-Universal amplifiers be driven by a Spectral preamplifier to ensure reliable operation.
(My thanks to member @David_Ten for calling attention to this writeup in another recent thread).
It is possible, of course, that the ultra-wide bandwidth of the 30SV could result in RF energy being introduced into the Pass amp that might adversely affect the amp’s sonics to some degree. That would depend in part on the source components, and perhaps also on the RFI environment at your location. But if the combination sounds good in your particular setup it is good :-)

I do love the Aviors even with this issue. There are revealing, I can hear each instrument, female vocals are so inviting, and basically the music is more exciting.
The reason I raised the possibility in my earlier post that the issue might be due to the Aviors having greater frequency extension in the ultrasonic region than the previous speakers (which they do) is that you like the sonics the Aviors are providing. Which suggests the possibility that high volume levels are causing your ears to hurt as a result of frequencies that are too high to be directly perceivable. Not sure what to suggest to test that hypothesis, though. As one of the others suggested earlier try pointing them straight ahead if they are presently toed in. Or perhaps as an experiment temporarily point them a bit toward the side-walls, away from the listening position, which at the listening position should result in high frequencies being attenuated more than low and mid-range frequencies. Although I realize that the weight of the speakers will likely make those experiments problematical.
