Jadis Monoblock Amplifiers

While it might be part of their sound

This is, definitely, an unavoidable question/concern.
there are some capacitors in Jadis I'd swap out in a hurry, and you would gain a bit of what was lost back.

Those big blue ones? They don't look super fancy. . .
 
(...) It's very obvious Jadis has less feedback based on measurements. While it might be part of their sound there are some capacitors in Jadis I'd swap out in a hurry, and you would gain a bit of what was lost back.

But than you would sacrifice the "Jadis sound" in the technology's table ...

There was a lot of debate on Jadis design choices, even in old WBF threads. IMO they are one of the most misunderstood brands.

The blue ones might be fine. They're not cheap cans. The issue is at some voltages there just aren't any options. IME seeking the highest C rating however isn't the clear winner for sound - it just isn't a factor that does or does not make good sound. It's more about some of the film caps. I'd have to study the circuit but I see some I consider overly bland.

Na. They don't use anything far enough from anything else that I'd call it signature defining.
 
Would you guys take JA120 over VAC Signature 200iq monos ?
 
NOT with your speakers, I would not ...I would not take VAC 200 either though, but for personal sonic preferences. If u go VAC 200, I d only go with the mono variant.
What do you not like about the VAC 200? Just curious as I know sonic preferences are very personal ... just curious as to what you are hearing that you don't like?

Thanks!

I don't find KT-88, or its variants particularly "musical" to my preferences... Yes, these tubes in some designs have more power, and drive, and slam, and MIGHT drive some speakers with difficult loads (like Wilsons & Thiels) well, but to me most of that tube family lacks textural liquidity, and naturalness that I find in the the well designed amps using EL-34, or 845 tubes. I ve heard exceptions however, like the new Conrad Johnson line of amps , but that is also very system specific. Naturally the above is strictly my experience & preferences.
 
Well since i live 3 hours away from the Jadis factory why not try.
I will try to borrow a DA88S integrated just to hear how that sounds on my speakers vs SS class A.
If it's really good i could try monoblocks later on.

Ok guys i'll be demoing a DA88S very soon on my Thiels, first tube amp i will try since i have the 3.7s

Fair enough -- but which EL34 amplifier gets you to 100 or more watts (other than JA200)?
 
Yes, as well as VTL.

My mistake – – I should've also specified Class A.

I believe, that the EAR 534 power amp bridged, can give you a 100 watts.

You are correct!

Does anybody know how the EAR 534 sounds versus a Jadis amplifier?

Back in the mid 90s, I owned a complete Jadis system with JA200 monoblocks. It sounded incredible. Huge soundstage; glorious really, but it was unstable and unreliable. I had to get rid of it. Also the gold finish quality was very poor, IMG_1063.jpeg

That's why they came out with the Mk. II version.

Yes it makes me sad also to recall my soiree in Jadis around the same time --HP you devil :mad:(RIP) up till early2000's with JD1 /JS2 /3 /JA 100 Mono blocks /Defy 7/DA60 plus the grief experienced with Amps failing Power ( not output)Transformers consistently taking out the 150 Ohm resistors across the tubes /etc /etc I could go on but the wallet draining and shipping these beasts was nerve wracking a great pity as when working sounding glorious.

When my Tech declared them accidents waiting to happen--I moved everything on. And yes some were MkII versions.
I pray they have improved in 024--God Willing.
