JADIS DEFY7, can not get it to sing

@ davey,,can you prove the jadis 500 monos have pure copper posts? or how about the mac, ARC, Cary,,do they employ pure copper posts/connects in their designs? 
Its a industry standard to use brass. Sure the mod may only gaina  1% pop in sound,,but perahps more,,more zing, higher, smoother  connectivity transition/flow of electrons. For $20 a pair , and only changing the posts you use,,it might be worth it 100% copper vs 65% copper. 
+ the thin wire on the cayin from board to post,,who knows what it is made of,,i suspect all amps use this tiny whoknowwhat quality wire...
I  will mod to 100% pure silver,,and a  thicker grade.  If you can show Jadis uses high quality pure silver from board to post,,I'll hold on that mod..When my tech emoves that wire from the 8 post jacks,,I will find out how thick and what  is the elements  of the wire,,,,,My guess it is copper,,, but who knows....For small change its worth it to change those speaker post wires to pure silver. 
Remember its in the upper mids/high fq,'s is where we are all after ~~zing N sparkles~~The swifter the current flow, more shimmerings, sparkles, clarity. 
Oh also on the speaker wire,,there is a idea thata  solid wire conducts superior to tiny strand wire. 
I will have a  14ga 85% silver solid strand...I think that will makea  nice mod in delivering fq's with more authority. 

All those mods will most likely spoil the voiceing of the Jadis.  It will be unsaleable after the mods.  Too much silver is never good. 

@stereo5   +1

The OP just seems to be on a quest that is his own...with little thought to any of these factors. I am off this thread...total waste of time.

@ Stereo5,,,i was wondering if the silver might alter tyhe voicing. 
Silver all over the place.
I'm going with it though. Unsaleable?
Right no the thing can't fetch morte than $3K + who pays the $300 ship?
a  80 lb amp is hard /slow to dump. most likely , in fact, is my final amp. 
If anyone knows the best caps for the Defy's voicing, please chime in. 
btw there is a  amp for sale on ebay,,he has all his vids on YT uploaded on his ebay listing,,you can hear the amp, ,,has M's Gold Silver Supreme/Black casing.  Realy super nice sound,,,beats any jadis  stereo show rooms sound. 
Tin caps are just that cheap caps,,Silver is the way to go .
as i say depends on the cap values which M's i employ, budget is a  issue, The Defy has quitea  few caps, could get expensive.

Ok so i do owe a  apology to the chinese maker of the LITE LS9 jadis clone, now that i have my speaker wires 
NOT CRISS CROSSED. Yep, had one black on the tweet going to top bipost, red going to lower bipost,,,made this discovery as i was employing the 
~~Sterling Silver 14 gague speaker wire , along with the copper strand (both are separated by insulation),,and so correct this HORRIFIC error,,now the pre amp can do its job,,as the screwed up wiring caused horrendous distortion. The Lite is working fine with stock EH AT7's.
( i took out the 182 NOS tubes, the EH are more beefy and solid).
So the amp has,,count them
~~16 speaker wires~~~= biwired X2 = 16, 8 copper strand + 6 sterling silver...
Now you ask, was this mod of any value??
Not sure, as the correction of the speaker wires was made at the same time as the added sterling silver mod. 
No I have no time going all copper to copper + silver.
On that mod we will never know the results.
But i can say, i LOVE this NON FATIGUING sound.
Now i am tube rolling and that discussion can be seen over at my topic, New Kids vs Old school tubes.
i can tell you, Old school's are superior.\
Now its a battle twix RCA long black plates vs Siemens, those test results will be complete next week, , just waiting for the shipments.
Both are legenady and who knows how thsi shootout will end. 
But this ican, the jadis is singing now. 
fatigue level , zero. ziltch. Nada. 
No hype, no bias, and no ~~Snakeoil~~~
I always knew jadis had this ~~esoteric design~~~, 
Took quite a bit of genius to figure out all the engineering of the Defy 7. 
IOW the Defy's potential is only ~~limited~~~ by the quality /lack of from the other units involved.
IOW if you employ speakers valued at $100K, yet the voicing is really ona  level of a  $1 sound imaging/fq resolution, the Jadis will sound likea   $1 amplifier, Likewise, give the Defy a  true (not fake) high fidelity speaker, the Defy will sing like a   true high fidelity amplifier.
This quality inherent in the Defy can not be ascribed to quitea  few other tube amplifiers, which are *colored* by the design flaws. 
= There is zero design flaws in the Defy. 
Its all there, just waiting for units that can at least come  near its perfection. 

The Lite LS9 is not all that bad really, sure the trans is a  bit weak, but sure boasts alot of line stage tubes. 
The cayin CD17 Mark1 has new Sparkoslab opamps,  6 singles  and have some Siemens Pcc88's and Siemens E88cc's arriving next week. See if that pops the fq resolution as well.
The Cayin 17 goes up to baton Rouge next week for a  mod of ~~20~~  M SGO caps.
Hopefully he will accept the job, as the board is machine soldered,,very tight squueze.
Lots of things happening down here in New Orleans,,,hopefully i can dump some tubes on my ebay listings, and get some cash to complete all these mods. 
Also , why has the audiophile community  failed to note the E80CC  blows away any 12AU7?
You guys need to go to ebay pick up a  pair and test them out. 
I'd say even a  Tungstrum E80CC would blow away the ~~Holy Grail ~~Tele  AU's.

oh look, china hifi  has the Lite back in stock, less than i paid 5 years ago.
exact same design. ,,no wait,,, they swaped the AT's and now employ AX's...wow, no doubt best tube pre under $1K. 
almost tempted to  pass up the cayin SC6 for this AX,,,but alas i am a cayin guy and i want the 4 AU's in the SC6 so i can employ~~yep you know~~4 E80CC's. 
I, already have 4 ax's in the Defy, why would i want 6 more????
But she's a  sweet lil pre, i can tell you.
 the AX is no doubt superior to the AT design.
