Recommendations for a sub $600 power strip?

All good suggestions....I've used a couple Power Strips that come with an integrated power cord--the ESP Essence and the Ensemble Power Point. Both are good, with the ESP a bit fuller in the bass and the Ensemble a bit geared to the mids. I like the Ensemble better IMS. They retail for $1K, but are found used for half that.

You can also find a good conditioner (non-current limiting) for <$600--used--such as the Running Springs Haley, Blue Circle MR1200, Richard Gray 400 or Audio Magic Stealth. I've used the Haley, Gray, and Stealth. Both the Haley and Stealth provided a silent background with great detail, and an enveloping and expansive soudstage. Both are very good values on the used market.

HCM Audio is selling the Tripp Lite HTPowerbar10 for only $88.

Call Harry at 800/222-3465 and ask how it sounds.

I have had fine sonics using the very top of the line version of Mapleshade Records Power Strip. $340, and a 30 day money back guarantee seems a good bet for your home trial.
Due to the somewhat aggressive nature of the Mapleshade website self-advertising, some are inclined to discount the possibility that this is as good as it really is.
But, this has proved to be a real positive surprise, without breaking the bank, even at full retail.
Just overlook the strangely flimsy DIY appearance which disguises a very well implemented audio solution.

Yet another choice: The PS Audio Juice Bar offers a very nice 6 way power strip: no filters or regulation of any kind. I have been pleased with it's performance in my family room system. Not so sure I would want to use any power strip in my high resolution system though.

I do use an Audio Magic Stealth in my main system. Agree with Richards that the Stealth is worth a listen if you've got the $$$.

Can anybody tell me what the difference between the Juice Bar and Q-bar is? They look identical to me except that sideways bit on the recepitcals.
