Anyone tried an Audio Magic Pulse Gen ZX in their TRL DUDE preamp?

Dorkwad,

No experience with the Dude, but I have a lot of experience with the Pulse Gens.  I put one in my MW Sony 5400.  The improvement was subtle.  I have the AM speaker clarifiers, which are basically Pulse Gens for speakers.  I also have an AM Miniref power purifier with Pulse Gen technology, so my room is pretty well treated with pulse gens.  I have my AM Mini Ref placed strategically between the power supply and business end of my Coincident Statement Line Stage preamp, and the physical proximity of the pulse gen in the MiniRef makes a huge improvement in the performance of my preamp.  The bottom line with the pulse gens is that you have to try them and see what they do.  It depends in part on the equipment, but it also depends on how much RFI/EMI is present in your room.  BTW, you can evaluate the pulse gen in your MW Sony quite easily.  Just remove the cover and tape the leads to the inside of the AC receptacle.  Power up the player and give it an hour before you give a listen.

Thank you, Brownsfan.  I'm going to try your last point and see.  I should be able to do the same thing with the DUDE.  I'm sure there would be an extra benefit overall by using a Pulse Gen in both the DUDE and the MW Sony.

Bill,
    Roughly, what would be the cost of all the upgrades you mentioned if I were so inclined?

I would need to see your unit first as they are all a tad different. The wire upgrade should be under $100 total. The bridge rectifier upgrade would be under $50 total. The caps we need to talk and share pics. 

I think you have my email. My username here at gmail.

Dorkwad, Correct.  No need to solder them in place until you are sure you like what they do.  I think these do have an additive effect up to a point, at which you probably have enough units that you have the RFI/EMI in the vicinity of you gear canceled, at which point there may not be much benefit to adding more.   One other point.  They don't absolutely have to be wired inside the units to work, although they work better for a specific piece that way.  You could wire the leads up to a standard AC plug with enough wire to reach various pieces in your system and get an idea where to use them by placing them on top of the case.  As I said, my preamp benefits from physical proximity to the pulse gen inside the MiniRef even if it is not plugged into it.  Keep me posted on what you find.
