I have been a strong proponent of PurePower since Romy introduced me to their units maybe 10 years ago when I was a writer for www.enjoythemusic.com. My system has had their original 1500, two 2000+ and one 3000+ over the years, and still use two of ...

Happy that you finally got your unit back. Over two years later and I’m still waiting for mine to come back.Bill Gaw...

Two years ago, I sent two pp 2000+ units to the factory to have them updated and changed over to lithium batteries, and paid for the service in advance. About one year ago, I received one of the units back. After many calls, emails, etc. without...

A friend of mine had the same problem. He cured it by moving the pp unit as far away as possible from the cartridge.Bill...

My main 6 speakers are modified Edgar horns with 105 dB/ watt sensitivity, and the others are overhead emotive speakers with standard 90 dB/ watt sensitivity. There are two JL self powered f12 subs, and 4 self built subs with a sherbourn five channel...

each unit is connected to a separate adeptResponse power conditioner which has shielding for hot, ground and neutral. Each goes to a separate 30 amp circuit breaker on the systems in room 100amp feed from a 200 amp service. Had a separate ground po...

I have to agree with romy on all except one point. I have always had problems with my electricity even though I live out in the woods, but just 10 miles from the Seabrook nuclear power plant. My journey in improving this problem took up at least 20% ...

I sympathize with those who were caught up in the financial problems that pure power had when one of their salesmen went rogue and attempted to steal their product, which lead to a long court fight which they won. Obviously this didn't help th...

I have two of the pp+1500's in for review,and had Romy's 3000 before Richard brought it to Romy, and have to agree with Romy that the units surpass the old ones for sound quality. I don't know how much current his amps pull on turn on but I was runni...

Had an interesting problem with one of my 2000- units last night. Was listening to Rite of Spring fairly loudly and about 8 minute in there are two strong bass drum thwacks. On the firast one, onr of the units shut down all of the outlets, but didn't...

Remove the battery pack. Should lighten it considerably....

Let's see if I can magically produce a cd-dvd-preamp-remote volume conntrol-equalizer-wifi-d/a-save stations-and cost under $1000. And it will even tune in TV stations, record them, FM and internet files and even do a/d encoding up to 24/192. Can't b...

Do you think that recording 5 channels on BlueRay nowadays they record with 5 microphones on 5 independent channels?I admit that some of the so-called multichannel blurays have been made using possibly two channel masters and adding reverb for ha...

Sorry for this long rant but I feel a rebuttal is necessary.1. Back in the 90's you had 480 I video and 16/44 or dolby 2.1 analog audio. Then the sound was crap as was the video so you could get away with a crappy setup. Now we have 1080P video and 2...

I had the same problem with my 6 foot, bass horns , which were built from 3/4 inch high density fiberboard. On doing some measurements back then, it turned out that they were vibrating for a few milliseconds after a pulse, giving a decent rise time b...

Every day that I listen to my system, I thank God for Romy's perseverance with the pp2000. For the past 25 years I've fought the crappy electricity that comes to my house in the woods with everything from banks of 8 massive 2 and 3 KVA isolation tran...

Very interesting. Mine are 6 feet apart with the left and right controlling the amps on top of their own cabinets with source equipment and amps at least 3 feet away. The middle one supplying the source components sits on top of my main stand directl...

I have not noticed this problem running three of the units. But each one plugged into a separate circuit created by one adeptResponse aR2 and one aR1 unit. Also, I am grounding only through one of the pp2000 units.Maybe they filter out the PP2000 noi...

It's interesting that the most variation is in the upper bass, lower midrange. By eyeball,the peaks look like 240 and 480 Hz. or about the 2nd and 3rd harmonic of 60 Hz., although there is only a slight peak at 60. Is that a fluke or related to some...

Thank god for partial retirement. Now, instead of delivering babies at 3:00 AM, I can listen to my system.Glad to hear the system is sounding so much better, especially with the ULF channels. Guess I'll have to get you up here again to retune my syst...

What I heard in your room on Saturday was superb reproduction of what was recorded from 40 Hz. up. This is ideal probably for a recording of a chamber group in a small hall without anybody present. One could hear the hall surroundings which replaced ...

If you ground one pp2000 to the wall, then ground the chassis of the other two or units to that one, then the noise should flow through the chassis to the single ground and not back to the hots. Then all units should have clean current from the hot....

Was priveleged to hear Romy's system on Saturday. I must say he's done a superb job both musically and esthetically over the past year, and except for one minor niggle has surpassed what he had in Boston. That was the very low bass, but he has stated...

Either my ears have gone bad or I must be the luckiest user of pure power regenerators. Have been using three for four months now and am still bowled over the improvement in my system. No matter what time of day I listen it sounds superb, but I do no...

Have been intently watching this discussion while on vacation. Returned last night and turned on system and one of my three units was given off a very low intensity buzz into the speakers. Detached the power cord and it went away and on replacing th...

Got mine on ebay for $125-150 each.Great for setting up system. Infinitely variable. Easy to adjust. Then after setup. used them on my back and side channels. No money lost.Built some tube traps years ago: To hold the fiberglass in shape get some gar...

Glad to see there'sanother reviewer taking bribes. Why would we otherwise praise a piece of equipment to high heaven? I personally prefer free passes to porno sites, like Newegg.com,or music direct,where I can lust over all those hot to trot pieces o...

Not across the plywood but condense on it. Similar to a glass of ice water with water condensing on the outer surface. Any water on plywood surface for period of time will cause wood rot and grow black fungus which is very harmful to your lungs and i...

You need to insulate around the horns. The attic around them will take on the outside temperature. The wood surface of the horns will be a poor insulator. Without insulation, it would be the equivalent of having a wall in the room without insulation,...
|
|
A thought. Why not super-insulate the top of the attic against the roof with 20-30 inches of fiberglass insulation or 12 inches of foam and leave the space around the mouths of the horns open to allow circulation of air around the horns. Would probab...
