Have you called ARC and spoken with Leonard already. I answered the question regarding the the LS3 owners pop in the other thread.That one may be due to DC offset in his amplifier,per ARC. Sounds like you may have a seperate issue. You can always contact Steve Huntley at his shop (Great american northern sound?) and ask him, He worked at ARC for years before going out on his own.
Tube pre-amp pop
Setting up my new system : AR pre SP16l, Bryston 4 BSST, Rotel RCD 1072, Paradigm 40.2. I am kind of happy with the temporary set up for now BUT the POP issue comes up with the AR pre. Any time I touch any button on the remote for mute/unmute/volume up/volumedown.....there is a pop not loud but annoying between the two speakers. Is it the normal static pops for AR vacum tube components or there is a defective with my AR pre ? Could anything be done to eliminate the "boops" noise without sending it back to AR? PS: the Bryston amp and the Rotel CPC are dead quite. Thanks
