Audio Magic Pulse Gen ZX Review Part 1 & 2


Category: Accessories

The following review is for a device to tweak/mod any component that uses AC. The device is called a Pulse Gen ZX from Audio Magic. The device is designed to control self-generated EMI/RFI (noise) within a component and to also condition and stabilize current flow. The size of the device is similar to that of a deck of cards. It requires two solder connections to the incoming “hot” and “neutral” wires inside the component (either right after the IEC or captured power cord).

First, let me say that this is the easiest tweak/mod that I have ever done (requiring soldering). It’s very straight forward and the two connections will always go to the “hot” and “neutral” wires (polarity is not an issue with this device). Because of the simplicity, ease of this tweak/mod, and the possibility of cumulative gains (see below for PART 2 to verify this), I think it makes it a sensible option for many people to try, both experienced tweakers/modders and the DIY beginners. It took me less than 15min to install this device into my component.

The results that I will be sharing are based on the installation of this device into my CD/DVD player (source), as I wanted to evaluate the affects to both audio and video. I used the Eagles “Hell Freezes Over” DVD as my main source of evaluation material.

Audio: Voices, instruments and musical presentation improved. Voices became more natural and clear. Instruments sounded even better, again the naturalness and clarity was what stood out. Lastly, the air and spaciousness of the soundstage came across as more real (extending both wider and deeper). All of these things made the presentation sound more musical, natural, accurate, and closer to feeling like the real performance was occurring right there in front of me.

Video: Clarity, colors, and picture definition were noticeable improvements. Skin and flesh tones were more natural looking. Colors more true. Smoothness of images, definition, and details were all more true to life.

The ease and simplicity of this tweak/mod, along with the positive results I experienced with this device, makes the Pulse Gen ZX easy for me to recommend to others. I think it offers great value and makes for an easy way to improve the performance each individual component with the possibility of additional cumulative gains (as more are installed). My understanding is that the gains should be cumulative, with each component in the system that you install this device in.

The cost of the device is $200 (self-installation). Is it worth it? I whole-heartedly think so, because of the ease and simplicity of installation, the “DIY ease factor” for beginner tweakers/modders, and the possibility of cumulative gains.

NOTE*** I will be doing a PART 2 to this review, as I plan to install an Audio Magic Pulse Gen ZX in my S.E.T. integrated tube amp. When I do, I will be able to evaluate and verify the possible benefits of cumulative gains.

Ozzy, I am thinking about buying two of these to go inside my Cary monoblocks. Here is why--- A couple of weeks ago, I decided to move my components around a bit prior to buying a new IC. This involved moving my Coincident Statement Line stage away from its location right next to my Audio Magic Mini Ref, which contains a pulse gen module internally. I immediately noticed a significant deterioration of sound. I let this go on for a couple days, thinking it might be due to moving my cables and power cords around. After 2 days, I couldn't take it any more and moved the Coincident pre amp back to its location next to the Audio Magic. The sound returned to its normal (glorious) state. I also use the Pulse Gens for speakers. In fact, I bought mine used from AudioMan58 above. I'm not sure what is going on with this Pulse Gen stuff, but in my experience it is for real.
I have had the Audio Magic Oracle conditioner since I first put my system together. It has two of the Pulse Gen Modules built in. Everything is plugged into it, and as I am limited with space restraints, my 300B amplifiers are located right above it. I assume the Modules are contributing some to my fine sound. I know this doesn't help answering your question....
The Oracle is also plugged into the wall with two Clairvoyant Liquid Air PCs.
Clarification: "I.P.F Modules" are in the Oracle. My recent research leads me to believe these are the same as the Pulse Gen Modules.
Thanks for the recent comments. I now have the Speaker Clairifiers and ordered 4 of the modules to go inside my components.

Two Questions:

First:
Where is the best place to install the unit?
I would think close to the transformer , but that may not be possible.

Second:
My Oppo 95 will require quite a bit of work to get to the IEC inside which I think I am capable. While I am in there I would also like to change the fuse to either HIFI Tuning or Synergistic. From the pictures I have been able to find of that area it looks like the fuse is soldered in. Strange.
So, I will install a fuse holder, but what the heck is the fuse value?
I have tried to reach Oppo but so far no response to that question.
Ozzy, try replacing the IEC inlet to an Oyaide if you want a more simple upgrade than installing a fuse holder. The inlet has a very similar effect to sound as changing the fuse (much in line with the Synergistic Fuse). Please let us know your results. I'm interested in modding my Oppo 95 as well!
