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

my guess would be a DC coupling capacitor has gone bad in the AR pre

You means dc leaking? Would it will damage all my other new components. It is a brand new pre-amp and I thought AR is a good products. Any SP16 owner outhere? Called AR two hours ago, left a message but no response yet.

It does sound as if you have a capacitor leaking dc. Leonard at ARC would be the person to contact. I don't see anyway to fix it w/o sending back to ARC.
It shouldn't damage your other equipment, if the pop is at a low level as you say. If it is a leaking cap, the pop can get louder though, at which point it is possible that it could harm your speakers or amplifier. Get it fixed now.
If it's brand new, just have your dealer replace it, or send it to ARC, it should be covered under warranty.

The Bryston and Rotel are solid state, correct? From my experiences, tube equipment sounds much better, but is more prone to issues like this than solid state equipment.
This is not normal ARC operation though.
