Jadis orchestra reference or DA50 for Proac D15?


I have a new Proac D15 loudspeaker (88db), driven by a Cayin A-50T integrated tube amplifier. The amp is 35wpc under ultralinear mode using four NOS Mullard EL34 tubes. I am considering replacing the amp with JOR or DA50, but not sure which one should I go ? Thanks a lot for your suggestions !!!

Yz_yang, you provided a lot of good information there, thank you!

I believe the DA50S should be able to run EL34/6CA7/KT77 tube variants without issue. Though it and the DA88S were featured with KT88 output tubes, I think, like the other cathode bias Jadis integrateds, running the smaller tubes would be no problem. If you have doubts, I can check with my friend, who is one of the principals at Jadis, and will provide the definitive answer.

Personally, in my DA30 and DA60, I very much prefer the EL34 over the 6550/KT88/KT90.
Hi Trelja, it will be a great thing to use EL34 tubes in DA50 !!! yes, please check with your friend at Jadis to confirm this. Thanks a lot !
Yz_yang, I have received confirmation from Jadis.

You can use EL34, 6CA7, KT88, 6550, KT90, and KT120. He has not tried KT77, so he feels uncomfortable to recommend them. But personally, I use them with no issue.

Many folks are talking about KT120 these days. According to him, they can be used in every Jadis except JA50, JA100 and JA250.
