Ozzy if you try moving the peas around let us know if it make ny difference. I'm planning on adding them one at a time. |
Ozzy, I also am perplexed why Audio Magic gear in general, and the Pulse generators in particular, don't get more attention. I have a pretty extensive line of AM products, including the Mini REf Gen II with pulse dampening, Liquid Air speaker cables, a Liquid Air XLR IC, a hand full of fuses, three duplexes, the Speaker Clarifier, a blue dot, 2 older generation power filters, and probably some other stuff I am forgetting. I have found it all to be superb. I am planning on picking up 2 pulse generators for my Cary monoblocks in a couple months. I will be eagerly awaiting your review. Don't be afraid to share preliminary impressions. Jerry states without hesitation his gear produces improvements that are not subtle, and that has been my take on this stuff as well. If you find you don't need all four, let me know! :) |
Ozzy, I would call or email Jerry for advice on placement inside your components. I suspect placement inside is not critical, although it seems I read placement next to the power supply is optimal. The fact that my Coincident pre benefits so much from placement next to my Mini Ref II tells me that the field generated by the pulse gen module is probably large enough to work anywhere inside the case.
One has to wonder about the new PEA modules as well. |
Ozzy, My understanding of the speaker clarifiers is similar to yours above. I think they do reduce emi rfi coming in with the cables, plus help out with the cross-overs when placed at the binding posts.
On the pulse dampeners, I know that when I unplug everything due to vacation or storms it takes a while for everything to return to normal. I think you will notice something right away in a quick A/B, but it may take a day or so to get the full effect. I'm thinking about using allegator clips to allow taking them in and out. I want to buy 2, and try them in my monoblocks then use them in my ModWright sony power supply and player to see which gives the biggest improvmement. |
Ozzy, my experience with one was similar. Too bad some people dismiss these without trying them. |
Ozzy, Possibly. Difficult to predict.
When you say it is too sharp, can you provide more details? What the pulse gen and all products resulting in better shielding against RFI gets me is first and foremost a clearing of a nasty nasal quality to the top end. This should not result in the kind of detail that gives one that excessively etched sound. In addition to this correction of timbral aberrations, the clearing and cleaning should give you a smoother and sweeter top end while at the same time resulting in more detail.
Its always possible that a piece of equipment is voiced in such a way as to become overly aggressive in the absence of normal background RFI- EMI. If the problem persists, I would recommend taking the Pulse Gen's out one at a time until you obtain the optimal sound. I do think the idea of using alligator clips is a good one, facilitating easy removal. That is what I intend to do, and that also allows me to hold the pulse gen if I sell the component. |
Hi5harry, Good info above. This idea also addresses something I have been wondering about. If you wire the pulse gen to the iec from the inside, you would have to make sure it is not defeated by the power switch, otherwise, its only going to be active when the equipment is turned on.
I obviously agree on the MiniRef II. Makes you wonder what the Oracle is like, doesn't it? I bought my MiniRef used from a guy who after finding how good the mini ref was had to have an Oracle. |
Ozzy, good to hear things are settling in a bit. Keep us posted.
Emoonie, how much info did you get from Jerry on the PEA's? I take it the three sizes vary with respect to the size of the field. If that is correct, do you know how large of a field each size creates? I could perhaps use 4 minis plus maybe one medium to place above my Mini Ref II and between the pre amp and its power supply. Or, if the field of the medium size is big enough, I might be better served to buy two medium size PEAs to go with each of my monoblocks, and perhaps the field would extend to the crossovers on my Maggies. |
Emoonie, Thanks. That is helpful. If the mediums have 4 x the field strength of the minis, I'm guessing that means 2 x the range. Assuming a mini probably has at least 18 inches of range, I should be able to place a medium on top of each monoblock and have the field extend to the crossovers.
I'm still waiting to hear back from Jerry, but the info you provided is a good start. I have also found Jerry's recommendations on target, but I am thinking one mini, one medium, and two pulse gens would allow me to fully assess where I am going to see improvements. |
Ozzy, From talking to Jerry, I gathered that the PEAs will do particularly well when placed above the ventilation holes of a metal cabinet component. I used one to good effect on my Audio Magic Mini Ref, which has an acrylic cabinet. I expect that placing one on top of your PS audio would result in improvements to everything plugged into the regenerator.
With the other 2 units, I would move them around to see where they have the greatest impact. They can be velcroed to the speaker binding posts for instance. |
Rays I also have a standard size. Dubai Jerry sent out an email t showing details on the three sizes. You might have to call him. |
Ozzy, I think what you said a couple posts above is key. Both the Pulse Gens and the PEAs are resulting in a "purer sounding" system. They are both, in different ways, removing something that is not right. With the pulse gens and speaker clarifiers in my system, its removing a bit of grunge in the high frequencies, giving at the same time a clearer more detailed sound that is also more relaxed. Those attributes don't commonly go together. I also find the Pea I have has added to the soundstage and depth.
There is a very high return on investment with these two "tweaks." |
Rja, I can tell you that when I moved my Coincident Statement Line stage (tube with SS rectification) away from its position on either side of my AM Mini Reference Power conditioner, which contains a pulse gen module, the system sound suffered rather dramatically. I can also tell you that Dan Wright offers installation of Pulse Gens in his ModWright Sony and Oppo players (tube analog stage, tube rectified). The speaker clarifiers are modified pulse gens that are intended to be used at the binding posts of speakers.
In theory, any equipment affected by RFI/EMI, tube or SS, should be improved by the pulse gens.; My experience is consistent with theory. |
Ozzy, I have my speaker clarifiers on the binding posts. Once I was listening and something wasn't right. I found that one of the speaker clarifiers had fallen off and was on the floor. I put it back on and after about 30 minutes everything returned to normal.
These cancel EMI/RFI not just in the cables, but also in the immediate vicinity of the clarifiers. EMI/RFI is very likely not a constant, so it may be that on a good day, you can remove them and not hear a difference, but on a bad day, you wish you had them back.
I tend to hang on to stuff once I am convinced it makes a difference, until and unless I find something else that addresses the same need better or cheaper. |
Guys, I've had the 3rd standard PEA in place for a while now. After buying the first, I was able to pick up a couple used from guys that found they could get by with one. This allowed me to get a pretty good feel for the benefit each additional PEA brought.
The first was installed on top of my AM Mini Ref, which also places it between the Coincident CSL power supply and preamp proper. After being in place about an hour, it was obvious the PEA wasn't going anywhere and I would do well to think about adding more. Especially given that this 1st PEA was on the middle shelf of my Maplehsade (4" thick maple shelves) rack, which I expect renders that PEA of no use to pieces located on the top and bottom shelves.
Addition of the second PEA found its best placement on top of one of my Cary mono blocks, which are placed between my Magnepan 3.7Rs. I moved them around a bit and back and forth from one monoblock to the other. Finally, I found that on top of the one of the Carys right above the input board gave maximum benefit. Overall, the benefit associated with adding the 2nd PEA was certainly noticeable but not quite at the level I saw in adding the first PEA.
The opportunity to pick up a 3rd PEA came along, so I figured it would make sense to locate another one above the input on the other mono block. Surprisingly, addition of this 3rd PEA resulted in a huge improvement--OMG level. I was expecting diminishing returns on addition of the 3rd one. What I got was just stunning beauty. Smooth, rich, clear, sweet, detailed, airy, dynamic, you name it I've got it at a substantially improved level. Now all I need is more time to listen.
The bottom line here is what I have said previously. These things are for real. They can be the last piece in bringing it all together and making things right. Well done Jerry! |
