My ex-tech ALWAYS returned original parts and capacitors when he repaired or recapped my vintage equipments. He returned even resistors without the lead. He said he has had enough complain like OP does, and sending back the original parts has reduced the numbers of the complains a lot. I'm pretty sure that it's a psychological effect.
If changing the resistors makes the huge difference the OP states, my guess would be the tech screwed something up. Probably used the wrong values.

baseless opinion,
Nice try
fact is
I never said it changed the entire sound, as to say I hada $1 million Jadis sound pre Zfoil, then after it went to say a basic am transistor handheld radio we used to listen to back in 1962.
Thats stretching.
Its more like this imagery, remeber as kids we used to take copper pennies and place them on rail tracks and see how the train flatens it to a pancake.
Thats more what the Zfoils did
The sound was flatened useless, worthless, lifeless, as if a train rolled over the sonic imagery
How 's that,more clear?

Richard Gray looked through his stash and found Corning NOS Metal
I am going to refuse.
I have Takman here on my desk and thats what we will employ.
When the tech put carbon film in the Jadis Defy7 plates,, the sound went to likea smooth pudding, = Great for jazz fans.
For me I told him get Takman Rey's in where he had the carbons,,
BINGO
THe magical jadis sound came back to life, Jadis stock NOS are almost identical sound to Takman Rey.
IMHO
Takman Rey's are THE resistor to beat.
And yes this includes Audio Notes copper and their Silver Tants.
<<<TAKMAN REY>>>>
Takman did not choose the word <<<REY>>>> just on a whim.
As they are the King of resistors for , pure, natural, zero coloration. Clean, full of zesty life musical reproduction.

It might be kinda' fun to build a couple of cheap identical amps side by side, one using the worst dogs__t parts one can find ($.03 capacitors off ebay, 200 for a dollar resistors, carbon pots, etc) and another with the type of parts people seem to usually use (say, available from Mouser, Digikey, etc) and see if they sound different.
I suspect they might. I'll tactfully avoid discussion of what the listening results might be.
Hmm, wonder if Jason might sponsor a few ACA boards...

My task is to explore upgrades in componts and posts results , This allow others to come along and google such and such cap, interconnect, resistor, tube etc etc etc,,and based on my personal obsverations, make some sort of hunch as to which direction they might wish to go. Thats all I am trying to do posting YT vid,s Audiogon messages, DIY posts.
We all must keep in mind in order to carry out these experiements
some of the following is necessary
1) Audio hobby budget\
2) a system taht is in stock form, nicely voiced, not colored, has some pureity inherent.
3) a sensitive ear/reference recordings
4) does not make 2 mods at same time,,= which did what? was it the res or the cap that did what.
= 1 mod at a time please
Just how do we describe these component swaps?
In the successes = its called a NUANCE, a MINISCULE,, or even a WINNER!!= nice size gains
The failures can be rated all the way from,, *not my preference*, to *not bad*, to *a bomb** = a complete waste of audio budget,,
The $300 on Vishay Zfoils was a disaster, Made the Jadis defy, the worlds finest voicing amplifier, sound like run-of-the-mill lush pull tube amp.
btw in Caps, I love Mundorf (= F&T) SupremeEVO Silvergold and EVO Silvergold.
Recall
The #1 mantra here on DIY
<<<, sometimes spending more on a part, can actually result in less.>>>> = aka The hype,
ain't that the truth,,,but not always true as well....
Takman Rey's @$1. Worlds finest (to my ears) **voicing** (yeah i know a res does not voice, i am speaking figuritatively) resistor.

forgot to add the why i rate Takman as *El Rey*
= does exactly what intended to do, w/o adding not taking away any sonics from the circuit,,
I read this comment on another forum last night while researching
Audio Note resistors
btw the author of that thread mentioned he did not care at all for Audio Note Tantalum resistors,,as he pulled each one out , and relistened,,he could tell that dullness/deadness in the low frequences that grated his nerves,,slowly drifted away each time he pulled a AN out his amp.,,,till the last one was gone,,I think he said,,,**good riddance**
With that , I slamed shut the door on anything <<TANTALUM>>>
yeah I know, tant is a metal, and Takman's are metal,, Thing is each lab employs dif metals, Takamn uses Nickle/Chromium = will sound different from Tantalum
Snakeoil buster here

Really? Your first post states otherwise. You appear to have drunk deeply at the fountain of component rolling to voice electronics. You will only spend money for no real gain.
You can measure of harmonic profile of the distortion, intermodulation distortion, and signal to noise ratio. If there is any different, maybe you can hear the sound different. Sometime effect of temperature coefficient and voltage coefficient is difficult to measure.
Audio Precision wrote about how to choose resistors type to get lower distortion. Do not listen to person who pretend to be objectivist but they do not understand how to be measure and of course they did not train how to listen.

Dude read your 1st post you are miss quoting yourself. Also how many Zfoils were installed At $300.00 that would be 20 to 30 resistors don't think there are that many in the audio path of a $1000.00 Jadis preamp.

I can accept this
All I am attempting to explain here,,wheter its valid/not true to scientific measurements, (not sure if any lab equipemnt is able to deteremire how 1 res sounds vs another), all I am saying is I can truthfully, not snakeoil half lie, tell you guys is that i heard the dif when randy installed HIS SUGGESTED, Tants in the Defy7 plate res.
Its smooth, But I much prefer the ORIGIANL Defy (=The Jadis Sound, which if you do not know is world famour is is the King of all amps made, 2nd to none), so I had already ordered Takman Rey, I had a good hunch these would RESTORE Jadis's supreme neutrailty. and the magica of jadis once again was alive
The Zfoils again half suggested by randy, alougth he wants me to take 100% of the $550 loss (He got $310 fee, 12 res),
Installed in thhe Jadis Line Stage DPL, hoping for this superior voicing, , proved to me Vishay is for industry, not audio.
How those things got hyped in audio, beats me.
Takman Rey's were developed for super low distortion, non coloring not in any degree. and guess what,
SUCCESS!!!!
Takman Rey is THE RESISTOR to beat.

I know, randy SPECIFICALLY said,, <<I NEED to make the order, as a few will have to be figured out by me, as to the values, as Vishay does not list THE EXACT ones I need, some yes, a few not>>> So I trusted him,,he goes<< well its like $240 for the 12,,and I need $60 for my calculation,,,,and said some of the ones we will need are very close to $30 each,,
so $240 is what we paid..

I was only trying to **update** the 20 yr old res in the Defy7 and Jadis Linestage, thats all.
The Jadis 's look *generic*,,,I was hoping to get more glassy highs with the latest new developments in Res techology which takman offers in the Rey,
= smae Jadis sound, or if we are lucky, a tad more sheens in the upper range, and female vocals.
I will know once Richrad Gray installs, res by res as he says, how the Tak voice in the DPL.
I will report back..We will 1st move to the plate 150k/1watt.
AS soon as i get results,,I will post.
hang tight
Takman Rey Is THE res to beat.
\ Rey = King.

just a half broke audio*pool* trying to sqeeen every bit of musical beaty from the Great Jadis Defy7.
btw the new Thors xovers was a <<home,,,no, a grand slam.
+ gets better
the below vid, is with Mundorf EVO GS 2.2
I figured,,,i think we can get something even more witha M Supreme EVO SG
and bam, Grand slam,, That vid will have to come later,,with the M Supreme EVO SG, 2.2 in the tweet, you can actually hear the bass strings in a Sophie Milman opening track.
The upper range is now more nuanced.This vid is with the EVO SG, not the newly added SUPREME EVO SG.

Here is a review on Audio Notes Tants.
I believe him.

Alternate purpose of this topic
Exposure
If someone is consideringa dding Zfoils,, at least they might come across my topic,,and reconsider their decision.'
Richard Gray told me before hand, <You are not going to like them>>>
Once I have Richard slowly but surely swap Jadis stock res to takman Rey, the DLP is finished, also the Defy is 100% upgraded as far as i wish to take it,,The other tech kept putting ideas in my head to swap out the <<diodes>> in the Defy to,,can't not recall the name,,,said<<< They will, open the sound stage>>>>
I felt that tiny little dioade had zero voicing effects, and so wisely declined.
Jadis stock diodes are PERFECTLY ok.
