Strange Loud Popping Sounds

Hi,
I recently bought a Primare i32 amp from a seller on A-gon and am experiencing a problem when spinning vinyl through it.
I hear loud pops while playing records.  They don't always occur but when they do they tend to start out as single pops and evolve into rapid pops as music gets louder on the record.  
It only happens when I use the Primare amp.  I switched back to my Cary SLI-80 amp and the problem went away, so I know it has something to do with the Primare amp.
This problem does not occur when playing other sources through the amp.  
My phono preamp is a Parasound JC-3 and my turntable is a Clearaudio Performance SEP with a Lyra Delos cartridge.  
Any ideas or theories?  I thought static was the cause but now I do not believe that is the case.  I am stumped.
Thanks!
Peter

I wonder if you are overloading your integrated amp with a over-gained phono signal.

i have the Lyra Delos, and I have a Whest ps.30r phono preamp with variable gain. When I use it at 60db gain, I have no issues. When I use it at 65db gain, it overloads the preamp (Audio Research LS-25).  

I also had had the same issue in the past with a variable gain PS Audio phono pre and the same ARC preamp, and a different cartridge.  Too much phono pre gain, and the signal cracks and pops when it got to the ARC LS-25.

no issues now, I just keep it at 60db gain.

hope this is helpful...
