power conditioning question gentlemen

      I,m considering a power conditioner /surge unit ,Two sunfire subs,nu vista intergrated(draws some juice) ,transport,dac,tt, phono section (dc-ac i may just plug in wall)  .Dedicated 20amp run directly to room x 2 hospital grade rec. I have been looking into richard grays,furman ref,shunyata etc.I have a unique set up here in nor cal.I am completley off grid!,I run a serious solar and res set up with a genny back up.The power is pretty consistant although during changes in genny start up or at time it does fluctuate a little .I never hear it or have never measured a spiked it drops slightly during those milliseconds.I would like to snag a used one in the 1k range .

Hi @oleschool

Sorry for not answering, I was having trouble following the models.

I don’t know anything about Core so I can’t comment. In general, power regenerators are the most expensive per watt. I really like and trust PurePower and PS Audio units.

The Furman conditioner with SMP, LiFT and voltage regulation is a great in-between unit. I use the Elite 15i PF and I'm very happy with it's performance. It has SMP and LiFT which is no joke. In addition to the measurements, I went without this unit for a while and really missed it.

My experience with Richard Gray was from a show in NY. They sold a bunch of units at the show to other vendors there because the power in the hotel was so crappy and they had the only AC conditioners which showed any  improvement at all. This was ages ago when I was shilling for InnerSound. Televisions were a big deal and the units visibly improved the displays.

But given your needs, I'd go Furman or step up to PS Audio/PurePower. Actually no, whe I'd do is stick with Furman and save the money for room acoustic treatment. :)


I was referring to the Furman, Equi=Tech, BPT type units. Think about the Equi=Core, you need one unit for each component. How does the cost then compare to a shelf mounted unit that offers several duplex outlets in one unit? I have no opinion about the Core product and don't mean to appear to discount them it's just that from a practicality standpoint I can't see an advantage. I was all set to purchase the P-2400 IT when I ran across my BPT unit for sale here on the 'gon. I gave up the surge protection offered by the Furman but it allowed me to try balanced power for about 1/3 the cost. I may still eventually sell the BPT and go with the Furman but for now I'm certainly enjoying the BPT. My system is completely silent under the music.

Given a choice between voltage regulation, and balanced power, I'd go with regulation in your situation, that is, going off grid for long periods of time. The regulation in the P2400 AR will keep your gear in optimal voltage ranges no matter what may come.

If you also have cable TV, I'd use a ground loop eliminator on it as well ($30 or less) unless it's built into the P2400.



What I try to do on these pages, because I'm a nice guy, is to relate MY experiences in this search for perfection....In fact, there is no such thing.  I must have spent a couple of hundred thousand dollars on the greatest next component only to be ultimately dissatisfied.  My point in the post above is to caution us to get the stuff we're  absolutely sure about.  My stuff is a few years old now, but still brings what I want to the party.  Buying and selling is for the dealers to play with.....but an excellent way for us to lighten our wallet in disappointment.  When I recommend listening to your own system without power conditioning, its what I have done and found it to be instructive,  and a wise effort FOR ME....and maybe for some others. 
The Reference Series units in this video offer balanced power. Note the difference in the size of the transformer as compared to the Elite series units, that's due to balanced power. The P-2400 weighs 90lbs. The consumer level IT Reference 20i offers balanced power and is twice the price of the P-2400-IT which is studio grade. I can't answer why but it seems to me that makes the P-2400 a great buy.
