Why did you choose the Furman?

Glad you got a Furman IT ref 20 --just had one of my audio buddies who was against pwr line conditioners --ie only plugged into dedicated outlets --Well ---he now has his whole system plugged into a ref IT 20 --including his 750watt mono blk amps and he has gone over the top :)--I have the ref IT 20 and agree with the improvements that you mentioned--there has always been alot of discussion on the gon about this --each has to make a judgement on his own --Rich
Drubin - The local stereo shop, now closed, carried Furmsan and I tried to purchase theirs in an auction but it went higher than I wanted. After that I found Vic, mentioned above, and he gave it very high praise.
Ontjesr - Sorry I wasn't clear, I have my entire system plugged into it, amp, pre, tuner, DAC and iTransport.
KUDOS on exploring, experimenting and experiencing one of the many realities that "can't work"/"make no sense"/"aren't scientific" in the realm of audio. I've had and appreciated(for the same reasons you mentioned) my Audio Magic Stealth XXX for a number of years now. Enjoy the music!! BTW: That book is readily available on eBay and Amazon. Well worth the investment.
I do not have a dedicated line.I do, I have two of them, so to speak; I say that because they are only dedicated in that nothing else is on those runs, but they share the same circuit box. One has a hospital grade outlet, I forget the model, and the other is a Porter Port from our own Albert Porter.
For the Audiogon members that own the Furman IT Reference 20i power conditioner;
Do you have dedicated power circuits supplying your entire system?
Does your amp sound different when plugged into the Furman IT Reference 20i power conditioner as apposed to a dedicated 20 amp outlet on a dedicated line? Please explain the difference in sound, conditioner as apposed to dedicated line.
Dedicated lines IMO do not impose greater quieting, than do power cond/filter.... with or without dedicated power lines. Dedicated power lines are good ideas, and they do improve things. Dedicated power cond/filters just do more to allow a system to achieve a higher level of performance. Albeit, som will say otherwise.
IMO, the one aspect of power conditioning I feel is always accurate is this... "With a power cond in place, you will hear less of what you are not hearing now." it's simple increase by subtraction.
If it in fact improves the sound itself too, then you are doubly blessed. For me, they took/take off the edgyness and gave greater apparent resolution from providing a darker back drop to the sound stage and thereby illuminating the images within it.
Can there be limitations? Sure. Limitations to the bandwidth being served, and current being passed. Noticeing these diffs is easy too... just plug right into the wall now and then when demoing conds or filters. this action is what recently prompted me to find a more free flowing power conditioner to replace the one I was using for my power train. I settled on trying a RSA haley. that was a good move IMO and I posted a short review of it here on the 'gone.
I find plugging directly to the power line allows greater dynamic thrust, speed and impact versus going through a conditioner. I don't care for the edge to the highs and mids which accompany that move. So a power cond/filter for me is a given. Which one however remains an ongoing pursuit, though right now things are quite acceptable.
I believe the Furman unit mentioned (and I also hear it is a great unit but somewhat pricy at retail)is also a regenerator and that in and of itself explains a lot. You are receiving a much lower distortion AC from it...whether from a dedicated line or not.
I have a PS Audio PPP and wish it was a 20 amp unit so I could use it with everything I have. It only puts out 1500 watts continous though so I run my main 600 watt/channel amp through a Hydra. I run all my source equipment, HT amp and TV through the PPP and it does indeed make a sonic difference.
One day the unit was off and passing regular unregulated/filtered AC as the lights went off the night before and the PPP shut down when the electricity came back on due to the surge(you just unplug it and plug it back in to reset it) and I turned on my stereo to listen to some music. It didn't have the dynamics and musical nature I was used to. I looked the system over and sue enough the PPP was off. After resetting it, the music came back to the same dynamics as usual.
Perhaps I am just used to the sound of my front end gear being plugged into the PPP but I did indeed notice a difference in sonics when it was on and off.
Point beinig is that I believe in power reconditioning and filtering from good units.
Maybe I should sell the PPP and Hydra 4 and get the Furman...
