Am I reading this right...you rolled in KT150's into your Defy amp?? Now you tell us you think the KT88's are a better match! KT150's were NOT designed to be rolled into the Defy amp! You Sir are very lucky you did Not damage your Defy...and DO NOT tell Jadis you did this, otherwise I would doubt that they would still warrant their transformer for you.
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.

Just blew a fuse in one tube,,thats all, we up the fuse amperage on the 88's... well actually i just sent Jadis a email showing off my Defy with new M caps,,I did let them know i tried out the 150’s in the Defy,,and the mids were too murky/muddled, not defined,,but that was with their caps,and my tech guy had one hell of a time biasing the 150’s,,3 rows were OK, 1 row of 3’ 150’s were not balanced right,,anyway,, I gave thema shot as I read somewhere here or another site *WOW the 150’s are awesome!!*,,I mean i guess in the right curcuit they MIGHT sound great, but surely not in any amp i want to consider.,.. IMHO the 120,150’s are a flop design. KT88 IMHO are King of all power tubes ever designed. Next would be the KT90, but thats a distant 2nd place. = Not relevant. and furthermore a 88 is a 88 is a 88, all have near exact characteristics. = No such Holy Grail snakeoil. anyway,, so the M caps have proven their weight in ~~Silver and Gold~~. I recommend to all tube amp owners to begin making mods to M caps Supreme when they fit,,if not go with the little brother to the Supreme EVO Oil SilverGold. You lose a good bit of definition, but if space is a constraint,,you have no choice. The white EVO are about 1/2 size the Supreme EVO. The Defy really came to life with the M caps. btw Jadis makesa I50, employs 150’s.. I have my doubts about the sound of that amp. These 88’s beat out pounding bass rifts.,. I just see the 150’s even the 120’s as an anomoly. Cool looking, but mid range?? Mush mealy?? Midrange is everything, next are sparkly highs. 88’s deliver both. Bass ounch is a huge bonus. None of these 3 fq ranges would have materalized with success, in the Defy w/o modding with M SESG (SILVERGOLD EVO SUPREME) Now, with the new M caps the Sparkoslab opamps in the cayin 17 Mark 1, now can finally voice their magic. Descrete opamps murdered IC ops, like Burr Browns. , LM’s and all others. New preamp near order. Lets see how that shootout goes off. Its a Cayin so i am expecting good things. and a new design Mark2,,been out some years, but no reviews, no YT vids, nada. Lets see if the cayin can feed the Defy with good vibes. ,,as another major brand, did not muster up,,/returned next day,,another set back..... I mean i could easily live with this Lite LS0 jadis clone pre,,its quiet, does not color the Defy’s purity at all. Yet I think the Defy has more to give up on Dynamics,,and this is where the Lite falls shourt,,Hi Fidelity,, not mid not low fidelity,,HIGH Fidelity. But as a true audiophile, we must keep on climbing til we reach the Summit,,,which i can glimpse from my base station ,,,,,Most of my mods were a success, others a flop...we expect to slip on some of the slopes,,,its part of the risks on this journey,,set backs should aspire to new heights. The kt150 $800 setback was just such one. Lucky I kept the kt88’s. |
will have to go with 6550's in the Defy,,, the tube Jadis originally installed in the amp,,stupid to sell the 12 off w/o listening to them 1st.. Now i have to rebuy the 12. I really love the clear voice and crystal highs of the 6550 vs the more murky kt88. man I really need to do more reserach before making costly decisions.. But i am more than sure this YT vid show the 6550 is my tube sound. https://www.youtube.com/watch?v=oC1AVIsqoB8&t=158s I went from 6550(not heard the tube) to kt90 to kt88, then kt150,, now running kt88,,,and now back to original Jadis recommended tube, 6550. Full circle, with a price to pay. |
