Jadis JP80 Owners - Please Help

Prologue: In a recent thread, I asked for advice on a pre-amp to go with my VTL 450s, Martin Logan SL3s, and Sony SCD777ES (Thanks to all who responded!)

I just found a Jadis JP80 used for what I believe is probably quite a good price (about USD2.2k equivalent in yen) but it comes without a manual. I cannot borrow it to test it in my system nor at the store because it is at the wholesale 'trade-in/used components' branch of a chain of reasonably high-end stores which I trust. I have listened to the JPS2, liked it a lot, and think I would be willing to put up the cash to buy the JP80 based on the Jadis family sound and excellent reputation of the JP80, figuring I could get out without too much financial pain if it just didn't work. My questions to JP80 owners are:
1) Are there other pre-amps you would prefer?
2) This appears to be a JP80 with a non-tube power supply. Has anyone compared the with-tube and non-tube power supply versions? Any comments?
3) Are there versions of the JP80 which have balanced input and outputs? Inputs on this one are all RCA.
4) Phono stage: This unit has one phono input. An early 1990s (matching dates of non-tube power supply) Japanese industry catalog suggests one phono input (sensitivity 500mV). I assume this means the JP80 in question has an MC stage. Would I be wrong in assuming this? Is this phono stage any good? Should it also have an MM stage?
5) Counterfeits: Does anybody know anything about Jadis counterfeits? (which products are counterfeited? any defining visual differences? etc.) I ask a) because I am in Asia, where counterfeits are rife, b) the dealer, while a good guy, probably wouldn't know a c/f Jadis from a real one, and c) my impression was that the more recent JP80MC was essentially unchanged from the JP80 but the front plate has a slightly different setup.
6) Photos: Would anyone be willing to send me a photo of the front/back/top(grills on OK) of their older (let's say early 1990s) JP80 (not JP80MC) by email? I ask because I can find no pictures of the JP80 anywhere, as mentioned the front plate is different from the JP80MCMkII, and the top-open view of the JP80MC on the Jadis website is quite a bit different from the grill-on view of the one I saw today (though as I check it again, it appears to be a 'below-deck' view).
Thanks in advance...

While I can't help to much with your main concerns I can toss in a few tidbits.I had a Defy 7mk4 amp. All Jadis amps are single ended;so all pre's would be also. I was unaware of the knock off problem.I guess something us state-side folk don't think about to much. Jadis is famous for their phono stages. I can't even imagine someone thinking of a MM input/w/ Jadis. Get a serial # and you might try Northstar Leading the Way (US distributer)--Their phone # is in most every Stereophile. Also my local dealer might be helpfull. He is one of the top dealers. 1-626-359-9131 (Brooks Berdan Ltd.)in Ca. Aside from the KO issue; He knows more than the distributer--every model.
I own an earlier (sn 150, early 90s) JP80. In answer to your questions:
1. While I have often been tempted to try another pre, and due to a chronic problem with the phono stage of my JP80 I have actually recently bought a Lamm phono stage, there still is no preamp I'd rather own, and I've had mine for about 10 years. Adding NOS Telefunken 803S tubes to it just reinforced that feeling!
2. I have never heard of a JP80 with a solid state power supply. Are you sure it's not tubed? There are only two tubes, an EL86 and an EF 86, in the power supply, towards the back, maybe you didn't notice them because of the size of the transformer?
3. Jadis didn't start using balanced inputs/outputs until recently. No early 90's one should have balanced connections.
4. I've similarly never heard of a JP80 without both a MM and MC input. You should check the tube complement--if there are two 6DJ8s towards the back and parallel to the back, and then 3 12AX7s to the right of them heading perpendicular to the front, you should have an MC stage with about 60 db of gain. No 6DJ8s, then there is only a MM stage. Notwithstanding the problems (RFI induced, I believe) I've had, I'd say the Jadis MC stage is superb, though a little noisy in comparison to today's stages (the Lamm is infinitely quieter, dead silent). Part of this is due to the use of 6DJ8s, which tend to go noisy quickly and are run at a very high level in this circuit, making them prone to wearing out quickly.
5. Can't speak as to counterfeits, but I would suggest that you get the serial number and run it by Jadis by contacting them through their website at Ecrans Jadis, as they note the problem themselves at the website. My unit looks like the ones you see today from the front, but the tube and cap layout behind the faceplate is different--the caps are black, with Jadis written on them, not the blue caps they started using a few years later, the caps are not lined up in banks as on the new ones, but rather are in various places around the tubes, and the line stage tubes (in addition to the MC and MM tubes I mentioned above) are behind and parallel to the front plate. Also, the twin volume controls are not linked, as they started doing about 1993 or 4. My face plate has, from left to right--mute switch, tape loop switch, MC/MM switch (that could tell you if you have an MC stage), source knob and the two volume knobs.
6. Unfortunately, I don't have any pictures that I can put on the net; hopefully my description of the front plate and the tube layout is of help.

You may be looking at one made for a non-US/European market, but it does not sound exactly like my early-90s model. I would contact Jadis in France, they should be able to help and are concerned about counterfeits. If this is the real deal, while there is some unit-to-unit fluctuation in sound, on the whole the JP80 is one of the most natural and musically satisfying preamps on the market, although it, in its original version, is not the last word in transparency and can sound slightly romantic, a little rolled in the highs and the bass. It is better suited for classical and jazz, as its dynamics are voiced to sound like what you'd hear in a concert hall, rather than a close up, instant-on/off dynamic you'd get from rock. Hope this helps to some extent. If I can find a picture to post on the web I'll let you know.
Rather than struggle around with the questions unanswered,contact:

KARINE at Jadis Fax# 33 468 788 515 and give her the datails --she will answer in full.

Don't use the Jadis E-mail-it's on the blink.

Good listening,
The early JP 80's from around 1986 do not use the tube power supply of the later units. Some may prefer the transistor units since they are "faster" sounding than the tube units. However, they probably are a little leaner sounding. It's a trade off.

Another way to spot an early JP 80 is the fact that they have a balance control and a volume control. The later units had dual volume pots.

The lack of the MC stage is really not anything to get excited about. You can drive a medium output cartridge with the MM stage quite easily. The hot set up with the JP 80 is to use the MM stage with a a good quality transformer such as the Audionote or Expressive. This will easily outperform the units with the MC stage.
