Static System Damage

Hello Folks:

Could really appreciate some advice here. My reference system is almost complete and my speakers are the Thiel 7.2.

Unfortunately, my Musical Fidelity A5 cd player seems to have been the culprit in a static grounding problem that went away after the company serviced the unit.

What happened is when I would touch my audio rack, a loud pop would shoot right through the system and into my speakers. One of my speakers was spared, but the other has a slightly narrow, congested and rattling like sound at louder volumes in the compound upper driver. Seems I need to replace it.

What worries me is that with all this money spent and with the absolute enjoyment that I get out of these components, is there a way a test the speakers crossover, my amplifiers and CJ preamp without literally having to take test probes and look at every single component on the pc board's to see if it is still performing to spec? Let alone sending them back to respective manufacturers and spending a fortune?

The good news is that the system still sounds very very good. I just want the best performance of what I invested in.

My thanks.

D.H.
