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

Received an e-mail from Bryston advised me to have the SP16
checked. I e-mailed Bryston the symtomp of my system last night. Will have to call ARC and to come down to the dealer tomorrow. He is a very nice guy but too busy to call ARC for my exchange after I file the complaints twice !

Have the Sp16 hook up to the 4 Bsst and a smaller Paradigm reference ( don't know what the model is ) at dealer, there is a very small pop from the speakers , not a loud "Boop" when switching mute on/off, others functions is normally quite. Leonard at ARC advised it could be the Bryston input got some dc leaking. Well, it is time to carry this 50 some pounds back to the dealer for checking. Any thoughts anyone ? I wonder if the speakers'sensitivity have somto do with the "Boops".

I took the amp and the pre-amp with my ICs to the dealer and to my surprise, there was no POP no BOOP noise . I felt kind of stupid for stressing out with owner.Back to my house, again there is a POP/BOOP. Blame it to my electric company or my builder as folks at Bryston said.

Boy I want to say it sounds like you run really efficient speakers but Paradigms are not overly efficient, I had 98db efficient Innersound Electrostats and I could hear everything and it always bothered me. My current VMPS speakers are I think 92db and I have no issues. Can you try another outlet just to see, lift the ground maybe,,,just throwning darts at the wall now but I hope you figure it out.........that sucks my friend.

Yeah, It not only sucks. It almost damages my long term relationship with the dealer since I take my frustration out on him. Thanks God, the dealer is a super understanding guy. I am trying out new ICs and Speaker Cables just for the hell of it. It may or may not fix issue.
