I see that you have posted this issue before, therefore lets just to recap what is happening...

• The sound is cutting out on BOTH speakers at normal listening levels.  (80 dB at 6 feet away from the speaker)
• You have swapped out both the Parasound A21 amp and Adcom GFP-915 preamp with something else and the sound is still cutting out.
• You have NOT changed the music source (Rotel 1072 CD player), and the CD player was having "skipping" problems in the past.

Questions:

• How long is the sound cutting out?  Does it come back on it's own, or do you have to power cycle any of the electronics to get it back?
• Is the CD player your only music source?  If not, does the sound cut out with other music sources?
• Have you checked the cable connections at the speaker to make sure you do not have a short or that one is loose?
• Have you changed out the cables (interconnects and speaker cables) to confirm there is not a bad cable causing a problem?  
• Are you sure it is not a AC power issue?  Either a bad outlet, bad power strip, power flickering off for a moment (causing the equipment to turn off and then back on)

@marley119  -  Based on your answers, it's starting to look like the problem maybe with the Rotel CD ???  If you tap the chassis of the CD player, does it skip and/or stop?  Do you have (or borrow) another CD/DVD/BluRay player you can temporarily swap in for the Rotel and test?

See what Rotel has to say.  In the meantime, if you have a CD lens cleaner (a disk with a little brush or pad on it that you put some alcohol on to clean it), it is worth a try.  You can get them on eBay for under $10.  Also try using the CD player without the shock absorbers under the feet.  Does it still skip when turning the volume up?  

What seems to be happening, is that once you reach a certain volume level, the vibration level coming through the player is enough to make it skip.  That raises another question.  Where does the CD player sit?  Is it in a stereo rack?  In a book shelf?  Is the speaker on the same book shelf?  You see where I'm going with this... How are the vibrations from the speakers getting to the CD player.

Good luck and let us know how it goes.

@marley119 - no problem.  Let us know how it goes.
