Jadis Fidelity


Somebody can tell me we do not see too many Jadis product on Audiogon? What do I have to expect(buy or sell) for a Jadis 100 (E34 Tubes) ? Do Jadis people keep their gears longer?

CWLondon, the 200 is a dream and you are lucky if you can get one. You are right in assuming, that they combine the best of the two worlds. The best Jadis preamp I know is a four chassis job, the JP-200 MC. MC stands for moving coil, so it has a phonostage, you can have a line stage version too. Next to all what has been said above, this gear has even more resolving ability and a wallop and a transient speeed which I have never-ever heard from anything else except in concert. Wonder what Rcprince and Gerrym5 will have to say..
which is the best preamp for Jadis amps,which brands of preamps matches well with Jadis,does it only combine well with a Jadis preamp or can a ss preamp also combine well with a Jadis amps?
Samaul, generally ss and tube combinations in a chain are poor bedfellows, if you want to use them full range. It makes sense here to also look at specs and compare input and output impedances of the gear you want to combine. A mismatch here can have a multitude of strange effects especially in the midrange. If you run multiple amps however and like a fast, tight and well defined bottom end, I've heard excellent results with a Jadis front end and various higher powered SS amps. I think its wrong to generalise. You have to use your own ears- and best another pair of female ears, well disposed to you and our passion -to find out.
If anyone wants to get a glimpse of what a Jadis is all about, please check out the preamp in the feature auction on the Audiogon home page. My amp features cosmetics along these lines. Stainless steel and 24k gold plated brass on the faceplate. Tubes/transformers/caps on top, sitting on a stainless steel bed, transformer covers in black and 24k gold. Side plates are real wood. But take a closer look. At the business end of things, and you will see that a Jadis is not just a pretty face. It is as serious as things ever get. THAT is why they sound so special. I once read a description of Jadis, "must be seen, and more importantly heard(so they say)". NO BS there. I don't think anyone can dispute the fact that Jadis presents a combination seemingly without peer. Those looks AND those parts... WOW!!!
So many questions....Cwlondon, the JA200s, and the more recent versions, the JA250s are the amps that will give you better bass with the rest of the Jadis sound we're all extolling. Again, haven't heard the 250s with their KT90s (probably a leaner sound than EL34s or KT88s), but I have heard JA200s with NOS KT88s and they are beautiful. Actually, though, I think the JA80s sound slightly better than the higher powered ones, just a personal opinion. Their bass is actually pretty good down to about 40-50 hz (I've never heard an amp better at reproducing a cello), it's below that they run out of steam and control. I've solved the problem by getting a 4-piece speaker system where I can use the 80s above the bass and a solid state amp (Meitners, which tonally are a decent match for the 80s) for the bass, although I wish the cut-off was at a lower frequency. As far as Jadis preamps go, Detlof is right, the JP200MC is the best full feature preamp I've ever heard, but its price is astronomical and it is a four-chasis design. They have a new model, the JP800, which is priced like the top of the line but I haven't heard it. The JP80MC, which I use, gives you most of the performance of the 200 and a great phono stage (it looks like the JPS2 Trelja refers to in the featured auctions--that's the line stage only version of the JP80). I had a problem with my preamp for a while recently (related to a mod, not Jadis), so had to make due with other preamps for a while, and can report that the top of the line VAC preamp works well with it and (here's a surprise) so did the new Innersound phono and line stages (my preamp runs into a solid state crossover now, which then goes to the amps; that may be part of the reason it worked so well, as I think Detlof's post is essentially correct, as a general rule). Still prefer the JP80 over both of them, but that Innersound was a shocker! And while I haven't heard them in my system, I think that the Herron and the Aesthetix units would also work well with Jadis amps, as they both were designed for music lovers. Still think that it's better not to mix and match unless you've tried the combination; I think Gerrym5 has with the Aesthetix, though, and he obviously liked it enough to buy it. Gerrym5, thanks for your offer, I'll contact you later.
