ARC 100.2/ GOT A PROBLEM


Well, I am a newbie for ARC AMP. Actually, I just upgrade my system to ARC LS16+100.2. Here is the problem, when I turn the AMP on, there have a subtle "bo" noise come out from speaker and right after ten more second another one.
It is really annoy. I am wondering if this is normal for such HI-END component. My CLASSE CA-100 never have such issue anyway.
Thanks

Well, now I have a clue. Yep, I always wait a couple of minutes until LS-16 heat up. So, based on Dave's and 9rw
confirmation "POP" sound is normal, I am kinda relieve. As long as it won't get worse, I can live with that. Thanks all your guys kindly help and suggestion.
IMHO, ARC100.2 is more open on high, and more transparent. Sound stage is definitely better. I would say, they are different leve of component.
I plugged in the power cord to a two prong power plug and that eliminated the hum. Anyone have any thoughts on this?
