    Jadis JPL

    Hi does anyone know the difference between the various JPL models, the JPL, JPL 2 Mk1, and MK2?

    I owned an early JPL- sn 2XX, as far as I remember. As far as I know the only difference for current models was the type of capacitors. Jadis never acknowledged many of the unofficial references mkX that were usually created by the distributors. If you are buying used get an early model cheap and have all capacitors, including the signals ones replaced. BTW, it is a great preamplifier, but I preferred the sound through the common inputs, avoiding the cathode coupled buffered CD input.

    Some people who have experience with the brand told me that Vcaps sound great in Jadis.

    Thanks. What is the difference you notice between the JPL and the AR?

    Can you check these Jadis preamp mods in the page, do they make sense to you, and will they work equally well on an early or a later model?

    My JPL went to a close friend who later bought an Audio Research REF3. We compared both preamplifiers and although the Jadis JPL had better midrange clarity the ARC had better bass and more extended treble. Please note that auditions only included classic vocal and instrumental music, including large orchestral and vocal pieces - we did not care to rock or electronic music. BTW, IMHO we can not compare the JPL to the JP80 - if it was not for double volume without remote possibility I could have happily stopped at the JP80.

    The only think I fully agree with Salvatore is that you should keep the same final value of the components you replace. All other comments are mainly preferences and reflect his own system.

    Thanks, I owned the Ref 3 and sold it off because I found it disappointing w.r.t NAT Audio on bass, separation, and dynamics for classical. I am interested in Jadis purely for the midrange, I compared it against the NAT and same result as with the Ref 3, but Jadis vocals and solo instruments had magic. SO maybe I should get a JPL and have those mods, and buy a NAT, and swap depending on mood

    All demos included Mussorgsky Pictures, Scherezade, and Mahler 2 beginning. Also Bach Cantata 140 choral and duet

    Does that mean JP80 is much superior?

    What was the amplifier and source? My friend had an ARC CD7, this could influence the result.

    Sorry to say, much, much superior ...

    Ok, I heard the JPS2 which is the same as the JP 80 without a phono stage.

    To answer the source question, I heard the Ref 3 with a Lector CD, and then Jadis with an Ayon CD. But that said, I know people who have replaced their CAT, VTL 7.5 Mk3 and other high end stuff with the NAT, and for a neutral, separation, real, dynamic preamp I am not looking at anything else. Jadis JPS2 for me had a very beautiful magic in the midrange, maybe accuracy snobs will call it tube distortion, not sure, but I loved it. It had very poor bass, dynamics and separation as compared to the NAT. So I want both, which is why I was looking at low cost used JPL and getting the mods mentioned in that link.

    Sorry, I apologize for my ignorance, what is the NAT and what was the amplifier being used?
