I've been thinking about this for a long time. We want the sound to be more organic, right ?
So I held on to the power wires from my amp with my right hand and stuck my left hand fingers into the socket. Of course I already had music loaded and playing, knowing that both hands would be occupied.
Unfortunately I was knocked unconscious before I could properly evaluate any improvement in the sound.
But, after two months in hospital I am back home and ready to experiment some more.
I plan to use dogs and cats this time in order to be in the listening position.
This would have the added benefit of a pre-cooked dinner at the end of the listening session.
