Steve -
It is not recommended that you bypass speaker leads at the amp with
capacitors. In the "old days" that was ok because of the limited
bandwidth of the output amplifiers. However, today's solid state machines
use integrated circuit output amp modules that may not enjoy having
10000pF placed across their outputs. I've seen this cause HF oscillations
that rapidly destroy those expensive little multi-legged bricks.
Use ferrite beads and cores, but no bypass caps.
