Jadis amps and pre-amps still competitive?

I agree with the posts above. The Jadis sound is extraordinarily like live music, but their equipment is expensive. I still have not heard a preamp I like better than my JP200, and the JP80 I owned for years was more than competitive with the Lamm L2, which is the next best line stage I've heard at length (plus you get a world-class phono stage as well). The amplifiers may give up a little in the frequency extremes to other designs (having owned JA80s for over 10 years, I could recognize their weaknesses), but they get the midrange right in a way few amplifiers I've heard do.

Joe, it's my understanding that the Jadis equipment, even with autobias, kind of ran tubes at or close to their limits (one reason my JA80s ate up most 6550 and EL-34 tubes I used in them); that could be one reason they sound so good.

I know that one guy currently at my dealer (Mike O'Keefe) probably sold more Jadis than anyone in the country for many years when he was at Audio Outlet, and he's the guy who sold me my JA80s and my JP200. I'd nominate him, if the dealer is interested in carrying the brand again. But in all honesty, it may take a bit of work, including a good repair facility network, to undo some of the damage done to the brand name in the past few years.

I think Joe's talking about the brand, JJ Tesla.

Yes they are, if you value the Jadis house sound (I personally think that sound will never go out of style). And they work fine with Lamm amps as well.

They don't NEED to be used together, although they do have an undeniable house sound.  I found my JP200 to work extremely well for years with my Lamm ML 1.1s, and I'm sure they would also mate well with my VAC amplifier (my JA80s sounded really good when I had a VAC preamp in the system).
