Who has Caps on their AC lines ???

I like my AC straight up no chaser.

There is quite a bit of discussion on this on the tweaks board over at audio asylum...start with a search on "auricap". The lack of AC rating is also discussed often. There are AC-rated caps that work well in this application.

I use 2 Auricaps .47 @ 600v in parallel on all my outlets as well (DIY Power Boxes) but I'm in the process of transfering them to inside the components. I also run 3 separate isolation transformers. one on my dac, one on my CDP, + and one on my preamp all on Dedicated lines. I also agree with Sean
do not get a small isolation tranformer, get one 2x3 times the size of the watts rated for the piece of gear pluged into it.

I have heard that some people have put the caps in the isolation transformer as well. Maybe I'll try that but with my other ones will that be to much of a good thing??

Benie: You want to place the caps near the input side of the iso's for greatest results. This reduces the amount of "muck" that the iso has to deal with.

After that, all you'll have to worry about is keeping the AC "clean" from behind the iso up to the component. This means running low impedance power cabling that is RFI / EMI resistant.

One could take further steps to improve the internal power supply of the components by adding increased filtering, snubbers on the rectifiers, etc...

Paying attention to system grounds and how they are implimented component by component can also help lower the noise floor. There are a couple of different grounding schemes that manufacturers use, some being more effective than others.

Obviously, one can go as "crazy" on this as they can afford to and / or spend the time on. If done in reasonable fashion and with some form of consistency though, the benefits are quite additive and beneficial in nature. Sean

Any Belden number for this from the top of your mind?
