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

OK so the Defy will 
~~~NOT ~~~ accept the E80's as a swap for the REQUIRED 12AU7,,,so my tech guy here in new orleans also did some reserach and explains ~~Some curcuits may accepta  swap of the AU for the E80,,but not the Defy~~~, so thats that,,gotta dump my stash of E80's on ebay, got about 50 of em.
Prices just reduced from 130 to 45 each...anyway,,he is now cking to see if the Defy will take the 150's, which i know will, and he is cking the bias,,as i bought 12 froma  ebay seller who buys stuff 2nd hand, these tubes were tested at ARC and some say *bad* *archs* etc,,but all in all most are good. They were ARC's *rejects* nothing really wrong with em,,got em for a  good price,,will post follow up,,,he says the amp was distortuing badly,,but i figured it was the preamp when turned above 1/3 vol gain,,,. anyway,,,i'll keep everyone posted on updates.
Just a pair of the 150's with 4 88's one channel, madea  HUGE sonic gain,,so i am expecting the Defy with 150's to be a  ~~Mind Blower~~~..now gotta find some Tele AU's in my stash,

OK new YT vid
with M SGO  EVO the Sparksolab opamps can now finally open up and sing their magic...My theory is, a  weak link can cripple stronger components within a system.
The cheap 2 cent caps in the pre, blocked the magic of the Sparksolab.descrete ops.

12 M SG caps for the Defy7 on the way.
= big brothers to the SGO EVO, about 40% more for the 12  caps, value is .47uf. ,. Audiogon member highly recommended  go with the non oil SG caps,,so  canceled the Oil and ordered the non oil,,they are larger,,my local tech guy Randy Cohen, in St Rock area of New Orleans,  may have to stand them up, or go sideways install.

bass /highs are good/clean. Mids a  tiny bit stressed.
My goal since late 1970's has been zero fatigue,,which has now been acheived. 
as i mention in the vid, 88/90/120/150's, all pretty close, We are talking nuances in each. My  20th C classical composers  collection is worth the extra expense of the 150's and I'd say the $800 investment was well worth it. A *nuance* superior over the 88's,,but when you add a  tad here,,a bit there =  nice sonic gains. 
After randy installs the M caps in the Defy7, will upload another YT vid,,My comment sections are blocked due to a  CV vid i made and am now censored for life.
*disruptaive dis-information*
No big deal, 
Plan to add a  cayin SC6 pre, shootout  Lite LS9 and Cayin SC6, one stays the other sold off.
last note, these M caps in the pre, really opened up the system. Contrary to some tech geeks on YT, with high tech testing data which claims a  cap is a cap is a cap, *as my tests show  near equal*,,,there is some nuances/musicality which test equipment can not measure.

Obviously you like an extended top-end. How bout using some room treatments? 

Figured the room treatment suggestion would come up, as i watched my vid ad figured should have placed one of my many persian rugs down as ~~room dampener/acoustically tr5eatment** no problem,, will do so tonight.
anyway,  will continue a long sries of YT uploads for 
1)m show off each piece of system
2) show off each mod
3) expose the crappy  stereo systems vids on YT all with 30 seconds of the  very worst recordings in terms of musical content/recording quality.
From marimbas, to chinese lute sytle, to a long boring drum solo,,, highly equalized/computerized mod recordings, I can not find even 1 stereo vid with muisc that shines and sparkles with vocals, high dynamics. 

Most sound like muisc passing througha  guitar fuzz pedal. 

Note my speakers are what they are,,nota   super large sound stage,,,these are a  mere 6 inch cone mid woofer,,,  Beginning in the 1970's Big speakers never impressed me That postulate holds true today,,Except i owe a  apology to a  YTer who posted his Defy7 set up with Jadis's  HUGE massive super heavy speakers,,which i might actually give approval , after several listenings. 
But not for me.. These Thors are perfect for my preference. 
anyway,, all comments will have to be taken over here, as YT has me permanently block to allow comments on any upload,,i am a  enemy to the state, as a  ~~promoter of anarchy with disruptive un-orthodox views, which instigate disharmony and confusion....* concerning CV19.
No big deal. 

I plan to make at least another 20 or so YT uploads. 
Some of  my ideas  may not go over well among some members of the audiophile community,, So be  that too. We are here for searching after high fidelity,, yet at the same time , exposing ~~The Snakeoil~~ so prevalent among this hobby past 50 years. 
Not once  was i tempted to  sip, guzzle  snort, nor inject ,  those gimmicks. 
And now in this post CV19 world, our stereo  bugdet must be managed with care and caution.

OK so here's possibilities, need help deciding.
After hearinga  all Jadis set up on YT with B&W speakers(nota  fan),  the system bristles with colors and dynamics,,as much as i can pick up via my computer speakers,,
so here's the thing..
I have modded the Lite pre amp with new M caps, and now the sound is more relaxed and ~~inviting~~~, But I think the Defy has more to offer. than what the Lite ~~jadis clone~~ can provide.
I was thinking gettinga  cayin SC6 preamp @ $1500..
or should i wait and see ifa  used jadis preamp pops up?
I need jadis preamp owners imput here,, as I have no experience with J's preamps. 
Iwo will the cayin be a step above the Lite, yet still below the J pre?
Meaning down the road most  likely upgrade to a   J pre?
Also , which  model from J should i be considering as a  match for the Defy.
