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)

between 80 and 90 , skipping and stopping, i swapped out original for the parasound and adcom , keeping the rotel cd, cuts out for second, checked cable connections when installed  parasound and adcom,, changed out tara omni bi wire for monster 16 gauge, banana clips, i have some gear it 14 gauge , outlet is good, strip is power protect av600. it is color coded and marked for tv, amp, cd, etc,  i did not follow these. under 80 is pleasant with no skips. no power flickering  paul

@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?

i have some rubber hock absorbers under cd player but tapping player does make it skip. if it is rotel cd player ,  you think it can be fixed 

the CD player has 3 main parts: the cd holder mechanical component (the plastic case), the reader (the laser eye) and the processor (the flat board with the little thingies) You can easily fix the mechanical part, clean the laser and even replace it, but fixing the board is pretty hopeless. The error you are describing seems more hopeless than not to me - home fixing wise.
