Just stumbled upon this lead unit for improving the mains supply to your hi-fi.
Seems an awful lot of cash to 'clean up' the supply! call me pessimistic but shouldn't the power supply in the equipment be able to supply suitable conditions for the equipment to operate as designed?
I'm afraid I'm putting these in the same category as the speaker 'wonder cables' that can be bought.
Or have I got it all wrong?
