Amazing ''Overachieving'' products...your pick?

I have owned both expensive gear (and I do mean expensive) and ''budget'' gear. Many components are mind-boggling on a price-paid versus performance ratio. Three of my favorites are:

1. The Bedini clarifier. This gizmo just plain works. You may like - or not - the difference it makes on your cd's. In my case, it clears up a lot of fog. The cheapest upgrade to ALL my cd's.

2. The Cayin TA-30 integrated amplifier . So much performance and flexibility for so little money. Put it up against anything up to 3 times the price, musically and from a build-quality perspective. Just plain amazing.

3. The Apple i-Pod Mini. Yes, even from in an audiophile application, playing cd's (not downloaded MP3's). You can snob it but you cannot ignore it.
