best power conditioner for less than 500 buckagroo


Can somebody suggest used power conditioners for < 500 bucks? I would like to use it for Bryston 4BST, Proceed Pre, Jolida CD100. Thanks

I am researching on Richard Grey 400, and Chang Lightspeed 6400. Any other suggestions would be welcomed and appreciated . I would like to get a contioner which will lower the noise floor but not alter my sound. Thanks again.

You can occasionally find a Tice Powerblock in that range. They are not a good as the latest and greatest highend offerings, but for $500 they are a steal.
I highly recommend an Audioprism Foundation III. You can purchase them used on the 'Gon from time to time for around $350.00.
I’ve said it before and I’ll say it again (several other Audiogon members have said it before me, that’s where I got the ideas from) Hook up / wire in / whatever it takes an isolation transformer 2.5 – 5 KVA.(Should run between $125-$400).
It will do wonders for your system beyond belief. Purchase used on Ebay.
See my two-channel system as an example of one way to achieve clean power.
Just my opinion.
Best regards...
