power conditioner

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)

 The hum was definitely coming from the preamp. The cause was a compact  fluorescent bulb in the dining room. We don't use the lights in dining room much. The bulb was putting noise in the line. You turn the lights on, the preamp had a hum. You turn them off and it was gone. Curiously the two rooms are not even on the same breaker. There was no ground loop. It never happen before or since. So I presume the old Adcom Ace 515 that I was using again before I bought the Furman, did not allow the noise through. It only happened shortly after I replaced the Adcom with the Furman. I just didn't put that together until after.
