Audiophiles hifi appreciation thread old and new

If anyone is near E3 I will pay beers for them to pop round and inspect...

I'm not sure what it could be... amp/speaker power combo no good? Maybe I am plugging the wrong things into the wrong things reg pre amps etc? I have a turntable and an Airport going into the Phono and Aux? The turntable doesn't have a pre amp but no idea if the Aux or Phono channel it's plugged into does have one?

Plug in a pair of headphones to your amp. When listening via headphones does it still sound awful?
