power conditioner

 I have had a number of power conditioners over the years. An Adcom Ace 515, PS Audio P300, Furman Elite 15 PFI and Shunyata Triton to name a few. I only use a power conditioner for my front end. I plug my amp straight into the wall.

 I leave all my power conditioners on all the time except the PS Audio. The Furman does sounds better if left on. Shunyata says that it take 3 days for the Triton to sound it's best. Nothing is going to protect you from a lightning strike. If there is a huge power surge it is not going to matter if the conditioner is on or off. Whole house surge protection is the better way to go.

 One of the dealers I frequent uses Torus conditioners in his rooms. If I was going to go with that type of active conditioning, the Torus would be my choice.

 I got rid of my Furman because I felt it did not isolate noise very well. I had a problem with an intermittent hum in my preamp. After much searching I figured out that the cause was a compact fluorescent bulb in the dining room. I thought the Furman should have cleaned the power a bit better. I never had this problem with the Adcom Ace or PS Audio conditioners.

 I got rid of my PS Audio because as I upgrade my front end with a tube preamp and CD player. It just couldn't put out enough power. I thought about a more powerful unit but decided that the Power Plants might just be too limiting. 

I now have a Shunyata Triton and I am very happy with it. It is a huge improvement in sound over the Furman Elite. 

I do not have the time in the testing you have . I can say that the elite is a relatively inexpensive furman at what 600? Or so . I love my p2400ar but it is selling at 1600 or so retailing at 2300 .. jmho this 2k plus range is where the real changes in conditiong etc are taking place upwards to 4k for regenerative power .. 
respect and cheers 

 I did not have any real complaints about the Furman other than I thought it should have helped protect against the hum. I actually thought something was wrong with my preamp and ended up sending it back to Audio Research. It was only when my dealer loaner (also ARC) did the same thing made me investigate deeper. But it also made me wonder what other things the Furman did not help protect against.

 I can not hazard a guess on how the PS Audio would compare. It was a while ago and my system has changed quite a bit. I was happy with it until I upgraded my CD player to one with a lot more tubes. Then it couldn't put out enough power and would kick off. 

 I would expect a huge difference between the sound of the Furman and the Shunyata Triton. The Triton retailed for $5000. while the Furman Elite 15 PFI lists for around $700. I think a far more fair and interesting comparison would be against the Shunyata Venom conditioner.

 But this is only my experiences in my system. I imagine power like everything else is very system dependent. So the conditioner that works best for me may not sound the best in another system.

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
