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

Great idea and I would think it would actually reduce the noise floor. You have plenty of room. The best tweaks or upgrades you can perform in terms of sound quality however are these few: I know from experience as I have done many, many mods to Dudes over the years and learned.

1) replace the signal wire throughout the unit with the new Duelund stranded 16 gauge wire in oil impregnated cloth from Parts Connextion. Must do! This includes all the RCA input and output runs.

2) Replace all the blue computer grade capacitors with Clarity TC film caps. This is the most important mod you can do. The improvement is spectacular. Contact me for more details.

3) Make sure your output caps are high quality ones such as Duelund or Jupiter copper foil and .47uf to 1 uf. 

4) Replace the wire in the high voltage B+ power supply with 14 gauge Neotech solid  core copper in Teflon. Get this from sonic craft.

5) Replace the common quality bridge rectifiers (2) with high quality ones from Parts

6) If you are good at DIY and soldering, then the last mod is replacing the resistors under the two 6sn7 tube stands with Talkman Rex or even better Audio Silver or Shinkoh. We can visit on this also. 

I performed the above improvements to my last Dude plus a couple of others. I lugged this Dude into several other systems with preamps costing over $12,000 and highly, highly reviewed. The Dude just overwhelmed them in short order. The design of the Dude is just unbeatable and these improvements do nothing to change the design, they simply improve parts quality. 

Thanks Bill.   How's your back been?  I've had back problems since I was 38 (64 now).

It sounds like #2 on your list would be the most improvement in sound--BUT, I'm guessing the most expensive one.  I do have the Dueland caps in my DUDE which also has the 4 inputs and remote.  I am using the black base Marconi tubes and have a couple other sets to use.  How much money is the #2 upgrade?  There are quite a few of the TC Clarity caps shown in the advertiser you sent me.  I already have the AM Pulse Gen ZX but haven't installed it yet. Thinking of getting another one for my Modwright 5400. 

Thanks for the info,
Bob

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.
