I believe you are correct, Doctor. Jadis and Pierre Gabriel appear to have parted ways. From what one of the principals told me, the company's intention was to be represented in North America by he and his brother, along with one additional, unnamed person. They're looking to set up a dealer network, but the language issue has been an impediment. The current retail price would come in at approximately $14K.
We both use the same small tube complement in the Jadis DA60, 7316 in the front and Sylvania Triple Mica Blackplate 5751 drivers. While you're running KT88, I like the JJ E34L in this amp. Of late, I'm curious to take a spin with the newly released JJ big bottle 6CA7, though I'm not exactly lacking on the low end.
It's funny to see all of the mediocre integrated amplifier suggestions in this thread. So far, despite all the equipment I've had or been around, integrated or not, nothing has provided me with as much enjoyment as the Jadis DA60. Not even close.
