Jadis JA30 Mk2, how great???

Here's a  look inside at the upgrades.
fast forward to 6 mintes,, in this vid,  I still have the Millennium tweeter, Which I dumped earlir this year and went WBer set up as heard above.
The dual WBers completely annihilates the Seas in midrange fq's, 
And the chinese paper tweeter is superior to the Seas Millennium ($700!!) tweeter by virture of a  higher sens @ 91 db. vs Millennium's crappy 87db. 

The Mundorf SESGO .47's on each tube really gave  up a  nice punch in bass guitar/drum sets. 
Glad i canceled the order for the M EVO.47's and went  with the SESGO. 
The blue adis wires inside are now upgraded to navships 10 gague silvercopper wires.

**not stable,,,flawed design,,** are the 2 comments i heard made by 2 dif local tech geeks.
I ain't buying. 


I think Jadis should have  only made the JA30 and JA80, a  few intergrated.
Whats the point in designing amps weighing over 80 lbs??

Even the JA80's are too heavy, Jadis should have made
JA30, JA60 and say about 4 or 5 intergrated and thats it.

@mozartfan  Funny you are talking about weight of amps. Yesterday, I was at a dealers and they suggested that I bring in my big Rowland to demo with their YG's. While this made some sense, as the YG's are notoriously difficult to drive, the idea of lugging this amp in..was a definite no no! The JA30 Mk2 mono blocks, while still heavy, are at least quite manageable in this regard. Something that I think maybe should be a factor for us to consider when it comes to living with an amp. 

IMHO The JA30 is my fav Jadis amp.
Has that bass  solid /tight punch of the JA200.
Its quite a  special amplifer. 
I saw a pair for 4G's months ago, 
Would love to swap the Defy out for the 30;'s. but as i have upgrades in the Defy, not doable.
The KT150's sound great. 
But honestly I can't tell much dif from el34,kt88, kt120's, 
any hoot...
The speakers in the vid below has Sonus Faber Guarneri, my guess is the newer models with that incredible Sacan speaker neo dymium magnet.
Thats one very special midwoofer for sure.
But of course for such a  propriatary special made mid, SF wants gold for tha speaker.
Like $17G's. 
I can say its the only xover speaker that I like. 
Now I know why folks go SF. 
Its really the only low sens xover speaker i consider  in competition with my WBers.
My future WBer design will surpass SF's Guarneri's. 
So I heard this vid,,then went back heard same track on my Defy7.
I mean its like 6 of one, half dozen the other.
The Defy's 12 tubes **might* offer a  slightly superior soundstage as far as separation of instruments, *maybe*,
 SF is a 2 way,.
My WBer design system is 
Dual WBers +  dual Seas W18E001 + a  paper tweeter.
So  its not a  fair shootout. 
I think if we placed a  stock Defy Kt88 vs a stock JA30/KT120's. 
Who knows how it would go. My tech says he does not care for the KT150's, prefers the KT120's, Opinion is a opinion.
these KT150's sound  super.
Both running Kt88's, possibly the JA30 would take  the cigar.
So if i can't obtain the wonderous JA30. this means I must continue developing my WBer with assist speakers.
Which is already in the plans, just waiting on cash. 
Besides the KT150's in this vid may be new, whereas my KT88's have 4k++ hours on them, not sure if well used  tubes  lose some of the sheen.


This YT vid is no doubt the best sound I've heard on any system, 2nd to none.
Thats one very unique midwoofer , carbon Fiber cone + massive Neo Dymium magnet motor. Don't know much about the tweeter. maybe its special as well.
87 db, which is too low for my cup of tea.
Which  only goes to show the ultimate power of these **little baby* monos.  can drive a  low sens speaker with dynamic performance. 
I'd say the Defy has 100 watts, but the lower watts of the JA30 are cleaner with more slam. 
...but then The Seas Thors was dual midwoofers, \vs this single,, Perhaps the Defy driving a single mid, might perform as well..Its hard to say. 
I found  the xover type speakers at 87db  no competition with a  higher sens WBer.
Completely annihilated the Thors. Smoked em...
