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...
