Audio Research LS 3 question

A time ago I had an Aragon 2004/18K combo, I was able to get use of an LS-3, it was an excellent peice but, I when I turned on the LS-3 (muted) and then switched on the 2004 it would "pop" the speakers no matter which way I tried it! Cosequently I had to pass on buying it. Has anyone any ideas what may have caused this? The house has since been rewired (new box) and I have installed Oyaide outlets and have them properly grounded. I had never had any problem what so ever with the Aragon combo when I had them. I now use a Classe CAP 151, no problems here either, I have an overwhelming want to buy an LS-3 and an amp but don't want to have trouble. Was there a mismatch in gain with that version of the LS-3 and the 2004, could it have been a defective mute relay or might it been something else? Help would be appericated-Thanks

It's an on going thing with ARC preamps. I have a LS-25MK II and the mute when switched on "pops". I am using a Levinson 335. It did not "pop when using ARC's amp which was a 100.2 at at he time.Here is what is printed in the LS25 manual.

"Some solid state amplifiers have a DC offset present at their input connections.(This of course should not be.)Operation of the manual mute switch with such an amplifier connected will result in a click or a pop in your loudspeaker (commensurate in level with the amount of the offset) each time the switch is activated. Repair or replacement of such amplifiers is suggested".
