Does the PEA units increase dynamics and have any impact in the mid-range? Is it relaxed because of a dulling in the leading edges, upper treble and bass?

Quick Pulse Gen Review: I have an Oppo 105 with a Bybee music rail. The player has an Acoustic Revive 18000 power cord w/Oyaide 079 plugs. I installed an AM Pulse Gen. After the players 200 hour break in, the AM Pulse Gen was overkill. I had an exaggeration in treble that covered up the mid-range. I pulled the unit out and eventually put an Oyaide 079 on it. I plugged it into my Audience Ar2p-To and voila, the pulse gen was balanced. Now I get transparency, solid bass, increased dynamics, sweeter voices, etc. I think the unit takes on some of the house sound of the power cord and connector it's closest to. I tried a Wattgate Silver plug, but the Oyaide was just right providing the right amount of dynamics without harshness. The PAD Canorus that is attached to the Audience PLC seemed to be enhanced with the Pulse Gen...

I am now curious of the PEA. I would like to install a mini inside the Oppo 105 right in front of the transformer (it has a perfect spot there for AM units). I would like to know if the PEA relaxes the sound by dulling dynamics? Does it have any impact on the mid range and bass? I currently have a nice ruler flat frequency balance, but my imaging is still very cloudy and I lack soundstage width. I'm hoping the PEA may assist without diminishing instrument weight, mid-range and dynamics.

On a side note, I found the highend_cc digital terminator to be another nice tweak. Only one is needed on the Digital Out of the Oppo, using another simultaneously on the In is too much of a good thing. This $20 tweak provides about 30% of the improvement my $400 Entreq ground conditioner made. Also I would highly recommend the Kemp QA Plug. Talk about amazing synergy with the Pulse Gen! On my system the Kemp QA Plug only sounds good at it's minimum setting. It takes the overall digital sound signature out of my system and replaces it with a very analogue (natural) sound. I can finally listen to Celine Dion with Magnepan 1.7's in great detail, yet with smoothness and refinement. It brings you one big step closer to a live performance for a small price. Another must have tweak!!

I have not tried the AM Speaker Clarifier. But have tried the Stein Speaker Match Plus. This is the only tweak I've found that has a huge impact in the mid-range (Kemp QA a distant second). It added much needed weight to all instruments. Soundstage width increased substantially. Imaging is better. Bass digs deep, and PRAT is more natural. However, it revealed a harshness in my system. The AM Pulse Gen helped smooth that out. But it was the Kemp QA plug that brought it all together.

I'm also going to give the Nordost Kones a try under the Oppo. Anyone tried the BC model yet?

Wow, Audiotunesx you and I have crossed equipment lines. My reply is based on my personal experience.

I am one of the all time tweaker's. I can't begin to tell you all of the tweaks I have tried. I feel everybody's equipment linked together has different reactions to different tweaks. Sometimes tweaks impress and sometimes they do not. More than 95% have come and gone in my system.

I installed a regular Pulse Gen inside my Oppo (not easy) and I do not think the treble changed at all. The sound became much more organic as they say.
But, I also have 3 Audience Ar2p-TO units plugged into my dedicated circuits. From there I am using PS Audio P10 in which the Oppo is then plugged into.

I have the standard PEA on top of my Oppo and it improves further the sound quality and picture quality. I think the PEA + Pulse Gen = 3.

I also use a digital terminator but I have mine on my Dac. All of the Oppo in and outs are used. You should also try some of the analog terminators on unused inputs on your preamp. They do help quiet things for a few bucks.

Now, I did try the Kemp QA unit along with the Acoustic Revive units, but I was not impressed enough to buy either of them.

I had the regular Stein units along with the ultra versions. At first I thought they were great but as time went on their effect became dull and uninteresting compared to not using them. Luckily I was able to send them back and I had 2 pairs of each for bi-wiring !

I own and like the Speaker Clarifiers. But, I think their use is to eliminate RF/EMI that may be riding on the speaker cables and my speaker cables are DIY versions so perhaps they help my situation more than if I used other speaker cables.

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!

Davehrab,

I beg to differ. There is magic here. Not everything that matters can be measured. And not everything that can be measured matters. Even Jack Bybee said, damned if I know, when asked how his technology works. But some folks need explanations to believe their own ears.
