Chinese Monoblocks Disgrace Jadis JA30

The comparison of my Chinese SEVGZEU tube monoblocks with my Jadis JA30 delivered a totally unexpected and shocking result. The JP30 drives the competitor devices to a stunning sound performance which proves that the true high end amplifiers come from China, not from France and cost only a third of the price!

Hello Rene, there’s clearly something wrong with your Jadis, and not representative of the sound quality that you should be getting from them.
Was there any possibility of sending these back to France for a check or has your dealer worked with Jadis on what the potential problem could be?
On a positive cheerful note: your rack build on your other channel was great to watch.
Beautiful work, and well done.
Take care,
Brian

They were in the shop several times and the seller found them to be OK, even after the two repairs which certainly required control measurements in the end. Send them to France? Jadis did not even deem me worthy of an answer to my mails on their contact site! And the dealer said: all Jadis devices produce a hum, that is normal....

could be that the jadis would do better within another context of system, ?
i have had jadis , the da88s integrated , and the amp was everything but bloated,
pure raw power , the mid bass and bass of this beast was incredible, the highs were very detailed but never harsh,
thinking about it, between this one , the leben cs600, line magnetic 219ia, line magnetic 805ia, ....if it was now, i would problably keep or the 219ia or the jadis,
the 219ia was easy to create a system around it, and it sounded very good indeed,
but i think i would have kept the jadis da88s, was way more difficult to form a system around it, it was less forgiven, and it showed what it was on the recording ....good or bad,
but when done right , with the right source and specially the right loudspeakers ,...it was heaven,

The Tannoy Kingdom with 92 dB is very easy to drive. Funny, how different experiences can be, but please let me specify the relevant aspect: With bass runs or even a big big orchestra the JA30 shows more power than the SEVGZEU, but it is unprecise and lacks snappiness and control, sounds overwhelming (really) but not like the real thing in a concert hall, where sound sources do not flow into each other. Anyway, thank you for the interesting feedback!

Rene, I bet the Applause 300b amp betters the Jadis easily

wait and see..... but let us not hope for too many wonders!

SEVGZEU was unknown for me !

You can find the amps in AliExpress. Or just google: SEVGZEU monoblocks

Hi Man. Really cool toys but do you know Jesus? Don't forget to subscribe to Jesus in case not miss eternity.

Sorry, I'm already registered with Buddha (as you could see in the enlightenment parts of the video). But thanks thanks for the hint...

@@renessoundlife235 The kicker is that Jesus studies Buddhism in Tibet, so he was technically a Buddhist as well.
