The biggest issue with power conditioners is one of high source impedance, something you don't want. You want to find one that provides a low source impedance while isolating all the power line garbage. BTW most re-generators tend to current limit, also a bad thing. If you would like more info you can email me.
Removing power conditioner...
So after a couple years of just assuming my system was better with a power conditioner in it vs none, I took mine out for a quick test and was suprised at how different it was. I think I like it better without.
However, it occurred to me that I would have an issue as one of the benefits of the conditioner was that it provided many outlets for all my components.
For those of you in the 'better without a conditioner' camp, do you use any sort of power-bar or similar item to plug in all your components?
I have a dedicated 20amp circuit for audio, but only one outlet.
Thanks in advance.

I have always used an Isotek Gemini or Isotek Multiway power bar with multiple outlets for my equipment. I just purchased one of the last remaining older generation Isotek 8 Multitway's for my system. It has industrial looks, is shielded, non current limiting, and is robustly built. The newer generation of Isotek power bar products do not look as heavy duty as the previous generation. My electronic engineer friend and audio technician in Germany told me that plugging all of the equipment into the same power bar allows for proper phasing/polarity which impacts the quality of the music. In fact, when a component is plugged into a plug and is out of phase, I notice a distinct change in bass and reduced stereo imaging. Now, phasing in Germany is really simple as I plug the Shuko plugs into the equipment without any interconnects plugged into it, then you push a button on a the phase detector and it will light up when the plug is correct phase/polarity. You do the same for all of the components. The power bar/extention is also checked for phase/polarity using one of those polairty checkers; http://www.vandenhul.com/p_IG01.aspx I do not hear many people in the US discussing the merits of correct phasing as we do in Germany. |
I am in the power conditioner use camp. I use prof audio grade Furman power factor correcting conditioners (PF Pro R) that have built in capacitance to aid in current surge demands form the equipment, particularly the power amps. I have one condiitoner for the power amps and one for the low level circuitry. Using both of these has always sounded better that straight from the wall. I too am also concerned about RF and line surges. My solid state power amps are too expensive to have them damaged by power line crap (an advantage for tubes I guess). It only takes a few micoseconds to destroy most semiconductors. I did have a Furman line conditioner (AR-12 II) that my CD deck (Cambridge Audio 840) did not like at all. I got noticable distortion in one channel that was removed when I changed conditioners. But this conditioner was a line voltage control device that used a multi-tapped transformer to keep output AC voltage at 120 V. |
I agree with Richard_stacy. None is probably better, unless you have really terrible power in your area. My only real concern, and the reason I do use a conditioner, is for the surge protection. I live in the Midwest and we have some real nasty thunder/electrical storms. I have however, gotten braver and now I plug my Krell amp directly into a wall receptacle, which is wired directly to a dedicated 20 amp circuit. |
While I found two power conditioners I tried detrimental to the sound of my system, I would strongly recommend that anyone plug into a surge protector, especially if you live in an area with frequent storms. I think anyone on this site has more than enough invested in their equipment to want to protect it. You aren't always going to be home to unplug your gear when the storms come along... |

I would say for me, it all depends. at one point I had my amps into a PS Audio p1000, and my front end into a P300, all into the same wall circuit. I sold the p300 and found i huge detriment. I bought another p300 and all was well again. I then found an ESP Reference power strip, decided to swap the stuff from the P300 into the ESP. Due to some power cord lengths, I could not put all the prior P300 stuff into the ESP. I didn't care for the results-----I then decided to use a different outlet for the ESP and had all front end into the ESP----now the ESP sounds better than the P300. I have been too happy with the current set up to tear it down and try the P300 into the same separate circuit--but I guess the moral of my story is, to make sure you can to spread the system to as many separate outlets as possible |
Ahhh, yes. A troubling subject for most of us...what when where and how of power products! As you know from our chat, I use Acoustic Revive RTP Ultimate's. They lay somewhere in between a power strip and conditioner. Basically, it is a solid aluminum box with Oyaide R-1 outlets modified to AR's spec but there is also some filler in the base of the casing that absorbs RFI/EMI and other nasties. The manufacture's description reads like some type of voodoo but it really does add a natural, organic, musical flavor without any real ill effect. It has no moving or mechanical parts. There are some pretty impressive reviews if you do a quick search. I find it hard to listen without them. They are also no limiting and I even am able to plug my massive Krell into one. I never thought that possible. The one downside is I occasionally get some ground issues, some devices don't like to be plugged in to them. I would guess it has something to do with how AR handles the ground inside the case. I can't deal with the power conditioners that I have heard. They all seem to have a nice wow factor but after some time their tricks become more noticeable and I realize that some bad stuff is happening to my music in order to give me that magic black background and perceived clarity. None for me, thanks! |

The power cable feeding the power conditioner is absolutely critical and often the weak link of any conditioning system. Many cables just can't keep-up. I've experienced this multiple times. On the other hand, an excellent power cable on a great conditioner or well-constructed power strip can benefit the entire system. |

Hammond makes some good quality inexpensive power strips, that provide no filtering, conditioning, or surge protection. They can be purchased online from the major industrial electronics distributors (Digikey, Mouser, Newark, etc). I use one of their models to expand the number of outlets that are provided on the BrickWall Surge Protector/Filter that I also use. Regards, -- Al |
