power conditioner

@lostbears

I can understand your confusion. Unfortunately almost NO power conditioner helps ground hum. Please see my blog here:

Furman makes an excellent product, and protects better than most surge protectors, and I do find they make modest improvements in sound quality. Please do not be discouraged if it did not remove hum.

Best,

Ronkent,  I tried a lot of there PC....including there---ultimate outlets--humbustres III------ two of there regenerators the last one being the premier----  which my friend sold for me n he told the gentleman it may not help.....but the guy said he wanted 2 try it anyway so my friend asked him 2 let him know if it worked in his home......when the guy got back 2 him he told him it did nothing for his ac problem......I still have the 2 humbusters III......I have moved 2 a new apartment 220 miles away n awhile ago I hooked the up in my new place n new system.....they did what they always did nothing except make the music sound dead.....I also had n still do quite a few of there power cords.....n they never did anything for me n I have had a lot of different high end equipment.....so bottom line is I do not even think about them when it comes 2 Power Conditioners or cords 

oleschool: "jmho this 2k plus range is where the real changes in conditiong etc are taking place upwards to 4k for regenerative power .."

Yahtzee!

I started my AC enhancement trials after the installation of dedicated 30 amp power lines with a Furman IT-Reference 20i ($3500), their TOTL conditioner then and now. Very well-built unit, but impact on sound was minimal, er, I mean "modest". I compared it to my ancient Chang Lightspeed CLS-6600ISO conditioner and the Chang was better, but still "modest". Sold the Furman and moved to a SR Powercell 10 Mk II and the improvement was like in the Wizard of Oz when it changes from B&W to color. Sold that one off in a period of financial hardship and went back to the Chang. The magic was gone but I adjusted over time (ie didn’t listen much and got hooked on vintage systems for a while). Years passed. Recently bought a pre-owned Powercell 10 UEF/FEQ ($2500-$3K for a pristine used unit including a TOTL SR power cord and FEQ unit) and the improvement in sound is transformational.

I would like to know if any of the owners of budget passive power conditioners have tried a reputable-brand, equivalent-cost power cord on their digital source instead of their current/previous power conditioner? If so, what power cord and what were your impressions of the relative effect of each on the sound of your system?

Best to all,
Dave

I had Furman n they were good.....but that was before they sold the company.....my friend didn't want 2 buy mine so he bought a new one.....this was after Furman sold....bought it at B&H Photo around were we both worked.....he didn't like it plus it hummed so he returned it n bought mine.....he like n kept it.....all I said 2 him was.....I told you.....this was back before 2009....good luck everyone.

power conditioners are not designed to address hum (if coming from your amps transformer). This is why you need a DC filter.

I recommend - what I use - an Emotiva CMX-2. Besides the fact that it "works", it is inexpensive (less than $100 if you wait for sale which Emotiva runs regularly) and doesn't limit current in any practical sense (i.e. technically it is not 100% passive but is 99, given the meaningful LEDS)
