Clean all connections from your Sony player and integrated processor/amps to the leads on your Watt/Puppies speakers with DeOxit Gold.
If you suspect a prior owner tinkered with the Watt/Puppies, assure the internal speaker + and - leads were properly reconnected to the internal speaker drivers (this step also helps you rule-out out-of-phase speaker connections).
