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

Thanks for your responses. I emailed with Michael Elliot, the original designer, who stated that a surge of up to 10 volts (12.5 watts) at power up and down is normal. I measured that, and came with well under 5 volts...no problem, and even between speakers. The worse part has still to be resolved. The right channel has a diminished output signal usually, and there is a slight crackling barely audible in the signal. The problem as I discovered today testing everything independantly is most definitely the amp. Any more suggestions?
Thank you
