Jadis amps and pre-amps still competitive?

Jadis sound good, but everyone I know who owned this brand experience failures of one kind or another.

New, they have become insanely expensive. The DA88 integrated I was interested in, went up from about £8000 to over £1200, in quite a short time and £/Euro rates have'nt changed that much. Recently, I listened to a second hand Jadis DA50 and next day, an Ayon Spark and Orion. On different systems, with the Jadis through Wilson Sasha's, probably not a great match and I'm not a Wilson fan. The Spark seemed streets ahead, to my ears and I bought that.
I have listened to a lot of tube amps in the last few years and Ayon seem to be up there with the best at the Moment.

The Jadis 80 monoblocks set up correctly with right speakers and cabling are simply magical wish I could afford them.
