b & w 804 s

speakers are cutting at not so high volume

speakers are cutting at not so high volume

What's happening on both speakers is rare, maybe an upstream component that's the culprit?

upstream, you mean component. i changed the amp, and preamp, the only thing is the cd 1072 rotel

According to their published dataset, the 804S have a minimum impedance of 3 Ohm. This means they're current hungry speakers. Maybe your amp is choking and limiting

parasound a21 amp and adcom gap 915 preamp

Is this happening for both at similar times?

yes, seems to

@marley119 you have to send the Amp companies an email and send the speaker maker an email then.

Cos those amps shouldn't be choking

@marley119 

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.

cool, thanks for your time, i emailed rotel, see what they have to say, thanks again,  paul

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.

thanks, rotel says it is the speaker's, but i am going to try what we talked about, another cd player  i will try disk cleaner and moving player
