Without wishing to be critical, you're all rather failing to see the elephant

in the room. The biggest corrupter of sonic purity is worn and dirty

electricity. Think of it. The electricity you're using today was quite likely

being squirted through a heavy industrial processing plant yesterday. It may

even have passed through a sewage works. Yes I know that's pretty disgusting

but we have to face the facts.
Now, I know that you can apply mains filters and proper on-line UPS units and

that will clean the electricity up a lot, but don't you think all that scrubbing

only makes it even more worn and takes some of the 'sharpness' out of the sound

you make with it?
No, the only answer is to use a rotary converter. By its mechanical action, this

will actually use the stale electricity to create brand new electricity. You

will be amazed at the improvement. The clarity will be so stunning you will

even be able to tell the point number of the kernel your OS is using, and it

has been said that under these conditions some people are able to detect the

nuances of the different formulations of the hard disk surface.

Say you have a poem and I have a tune.

Exchange them and we can both have a poem, a tune, and a song.
