Those spec sheets on the
BH/BZ/AX, all look similiar.
But note:
I am never using the vol on the preamp with much gain, My room is 10X12/8 ft ceiling, why crank it up??
= No reason at all.
The Jadis's trans , inspite of RUMORS of a *previous model* (a rumor I ain;'t buying). , the Jadis builds like tanks, indestructible.
If the BZ, BZ has over heating issues, the tube will blow before anything inisde the Jadis./
Besides there are resistors inside the Jadis, either the resist or tube will blow,,,
I will carefully note the BZ/BH's temp, while employed.
Also I made some changes in my speaker wiring, Added silver to the copper.
Thing is, as i was making that mod,,i noted one biwire was crossed wrong. I had one neg going to the opposite post, That is the left channel had
the black lines crisscrossed, and THIS was no doubt causing HAVOC/HIGH DISTORTION in that cahnnel and completely annihiliating /destroying, mulitiating the fq resolution.
.
So correcting that ~~unforgivable~~ error
OKUS adding the silver sterling 92% silver line with fat copper strand.
= the resolution of fq's in super.
This Jadis sings now.
When I put more vol on the Lite LS9 Jadis clone, there is no ~~complete breakdown~~~ of fq's = the high level of distortion (which i attributed to the pre's low level of build quality) has all disappeared.
Perhaps the added silver did nothing at all to gain high fq resolution..= IOW was the whole issue the crisscrossed speaker wires??
Or did thev added silver add a clean, clear, nice gain in resolution???
I have no idea and will not make any experiements with
all copper vs
silver/copper.
Time constraints.
The Bz/s'Bh's , will arrive late this week, will report back on how that tube roll went off.
Let me finsih by saying the sound is completely
~Non Fatiguing~ = Zero fatigue Factor~~ (aka ZFF)
I loistened to Mahavishnu Orchestra, Live Central park, and wasblown away at what serenity overcame me , which never on previous systems experienced.
That record is not high fidelity studio, Diana Krall was mesmerizing.
I could retire from this mod adventure with what i am getting from the system.
But as a seeker of high fidelity, this desire to make futher discoveries is calling me onwards.
I have 20 M SGO caps to be employed in my cayin cd 17 Mark1.
later this year will rebuild the Thors xovers with M high level caps.
Along with the cayin SC6.
The SC6 employs 4 AU's,,well you already know what i plan to do, and will ck the E80CC's tempt while in play, and also the heat level on tops of trans.
Cayin is like Jdais, build quality impeccable, ~~build like tanks~
YT vid update comming Sunday. will post a link.
But as a DIY member noted, a YT vid offers little in forminga opinion on a stereo sound.
I agree in part only.
After listening to countless YT uploads of stereo's in performance, I can now hear through the compressed replay.
Here is a example froma YT vid with a guy showing off the M high level caps mod in his amp.
I can hear the M caps singing GORGEOUS.
Not the vid I was looking for , yet another testimony to M caps singing ~~Like Angels~~~

Here is the reference vid i was looking for.

Now listen to this Class D/Class F sound with Jadis; audition room at a stereo show
This is not the vid I was looking for, but it will work, showing how a speaker can drag down a complete $100K Jadis set up, to ~~Class F ~~ sound.
https://www.youtube.com/watch?v=CIut7iVo7DM&t=291s
and note carefully in this vid, where you can see one of the best mid/tweets ever made.
The Seas Millenium!!!, UNREAL, either the xover design/parts or that mid range is driving the entire Jadis + Millenium down to grade
Class F.
No I can not grant a ~~Grade D~~ to this horrific atrocious sound level.
This is from a Munich 2019 show
https://www.youtube.com/watch?v=Hzbz4b09bH8
So agisnt the opinion of the DIY member, a stereo 's quality of resolution can be noted, at least on most vids. If you have a
1) trained ear/sensibility
2) practice makes perfect
3) listening attentively
4) replay as often as needed to draw some conclusions.
Every Jadis showroom upload on YT, , has these horrific speaker set ups, dragging, what otherwise could be a Pure Class A sound down to
~~Pure Class D~~ And in this Munich show, down to pure class F Minus resolution of fq's.
