Help Please Woofer Pumping Is it Amp, CD or ?


Fellow Audiogoners,
I have a pair of Amphion Argon2's whose woofers sometimes pump. I recently blew a voice coil, and I am starting to think the problem is up the chain..ie my amp or Cd player.
I use a Shanling T100 connected directly to a Counterpoint Solid 1 amp. There is a "Thump" with woofer cone outward movement powering up and down amp. Also sometimes I start to lose quality of sound from one side.
Could irratic behavior on either product be causing this pumping? Any ideas? Thank you

there is a slight crackling barely audible in the signal
Sounds like a a component is giving up: could be a cap... OR you have a very bad connection s/where. Very strange -- any technicians close by to check yr amp out?
