Jadis Defy can't sing with super high Fidelity PART 2


Why part 2?
Because she sings now, why?
Just arrived
Shugaung 12AX7T's from HK, dealer Douk audio,
WOWWW, unreal, IMHO no other 12AX7 comes even close to these Shugaung T's,. I mean this Defy in spite of the cheap chinese mock  Jadis 200 pre, the Defy has come to a  glorious resolution. 
I had no idea the front tubes were so so vital toa  sound ofa  tube amp.
I am using new Psvane's 12AU7 in the front, 4 12AX7T's just behind.
UNREAL. 



I will makea  YT vid today, and post it, and try to post a  link here.

I put my bet on these Shugaung 12AX7T's in a  shootout with every NOS EU 12AX7, any and all ina  shootout,
in 5 seconds or LESS the Shugaung would blow the entire bunch of  Siemens, Tele, Amperex, Mullards, all with ONE SHOT, .
These Shu are the quickest , most accurate, gun shooter in the west.

ck out my topic,, power tube shootout. 

1 channel is out on the  Defy,,, all mod YT vid uploda s are on HOLD at the moment,,should be 2 weeks and she'll be and running with ~~New Electrolytic caps~~~ + many other new mods,, 
Look for New and fantastic mods comming in 2 weeks.
New DIY power cords, new DIY interconnects,,plenty other  21st century mods. 
I told you guys i was going to be on  the cutting edge of non snakeoil oil mods. 


I have to really laugh at this thread. Here we have the OP stating that in his Jadis amp, he feels that the new KT150 tubes are a 'flop design' and that they are murky and mushy! Hello, can you say amp/tube mismatch!!!
Since the OP's amps were not designed to work with KT150's, I think his opinion of how these tubes sound is irrelevant. Only thing the OP should consider is how lucky he is that his amp didn't go up in smoke when he rolled in the wrong tubes, LOL. Oh, now I see he tells us that the amp has one channel out...seriously what a joke! 
Facts are
1) had not consulted with tech guy
2) Jadis no where says , can not use 150 in Defy
3) had no idea Jadis did not employ a  separate bias screw for each tube
Had  I consulted with randy Cohen,,,I am sure his research would have advised against using the 150,,,Randy kept calling, this is not the tube for this amp,, I had bought the tubes, unaqware of these isssues, = too late to return.
My loss of $400.
anyway.. have perfectly matcherd 6550's comming in 2 weeks from vivatubes. 
Jadis for some odd reason , did not employ a separate bias for each tube.
**Aesthetically it does not look beautifull  tom placea  separate bias screw on top of chassis.** End quote of Jadis engineers.
Well Cayin figured, screw aesthetics,,, its practical and intelligent to placea  bias screw on top of chassis, so owners can decide on which tubes they want,,and all do not absoluetly have to be perfectly matched..,. Which is why i recommend Cayin over Jdais. Cayin is the superior amp. Jadis is 2nd place, by a  mile.
So I am having most electrolytics changed out,,, not sure if Randy talked me into changing the 4 big electros,, have to call him today...Its about 20 electros, not counting the 4 big ones...anyway,,,mods are in proress and hoping for better things  to come.. Have to get over the big loss of the 150's, 
I would never bea  fan of 150's,,  neither 120's. Its a  shootout of kt88 and 6550 for me. 
They both look exactly same construction, The 88's i have are chinese, the 6550's, are russian. so basically its a  shootout between china and  russia. 
My guess  is yhe russian will offer a  sweeter mid range, but missing a  bit of bass puch the chinese 88 can boast.. 
Superior highs will be awarded to the russian 6550.
As I say, I bought the used amp, in 2008, had Svetlanan NOS 6550's, sold those off for $400,,,not some 12 yrs later rebuying at $450,,Sellers page mentions these 6550's are identical to the older 6550's, 
which i believe is the truth. 

Cayin is a superior amp to Jadis.
