would it still

Tried out an ARC LS 3 pre amp a bit ago mated to an Aragon 2004 amp but, using the mute control on the LS 3(when starting up and shutting down) produced a poping in the Apgoee speakers even though the sound was great with the 2004/LS 3! I didn't have any trouble with the Aragon 18K pre I was using with the 2004 at the time. Flash forward, I've since had the house rewired (new box to proper code now) and am thinking about an LS 3 again but this time mating with an ARC amp.
Should I be in fear that the same thing would happen still again (popping the speakers)? I don't want to incur any damage to the speakers and my outlets are properly grounded and incorperate Oyaide outlets now. Knowledgeable opinions would sure help me out! Thanks :{

I suspect that your LS3 had some DC at its outputs which caused the popping in/from your SS amp. Not unusual with tube/ss combos.

This is relatively unusual with tubed amps as their transformers will not pass the DC. Some SS amps have built in protection from DC and also keep it from passing DC, but these are usually the expensive 'overbuilt' models. DC passed on to the speakers in excess can damage the speakers as well as the amps.

If you are talking about a tubed ARC amp that would be a safe combo but if you are talking about an ARC SS amp I'd check out how it deals with excessive DC.

FWIW.
