Is my amp clipping?


I'm having a problem with my tweeter at moderetly loud levels (95db at listening position). Whenever there is a somewhat dynamic song -- with decent base -- the tweeter crackles and pops.

Speakers are 850 Rockets (91.5 Efficiency) from AV123 driven by Belles 350A Reference. Could the amp actually be clipping at such moderate volume levels?

If not the amp, could it be my Oppo CD player?

The noise is actually in every tweeter I tried -- even switched to a different speaker all together.

My preamp is by Van Alstine, I actually just got it as a used piece of equipment from his shop -- so it shouldn't have any crud...

So, noone's heard of Oppo CD players doing something like this?

Hmm...the tweeters still sound find at low volume. Has anyone heard of a CD player doing this?

Thanks guys.

This weekend I'll take all the components over to a friends house and see if the noise follows.

Has anyone had any CDs that were 99% fine but had a crackle or pop in one or two places?

Chadnliz,
Does the digital burp, churp occur randomly or always on the same material?

I tried the Oppo straight to the amp. Results are the same except the crackling noise is a little softer.

Well, it is the amp. Called powermodules the other day and, from what I understood, the mosfets are miss-timing. Sending the amp out today.
