Jadis in French means "in bygone days"...
As AW Audio started promoting their EA12, another Alain (Calmettes) was spending his free time designing tube amplifiers and in 1983 created Jadis to market his products. Almost 40 years later, Jadis still makes the most beautiful tube amps and has also ventured into the realm of digital electronics with a CD player and D/A converter, hence the well deserved motto: Jadis, aujourd'hui et demain.
Not too surprisingly, the two Alain met and did a few exhibitions together, using an ancestor of the JA30 pictured here.
I personally do not remember such a pairing, but can certainly accept the fact that it would have made a formidable combination.
Jadis is now renowned all around the world and are indeed distributed as far as Australia, but no other than Advance Audio, bringing to our "fatal shores" the likes of Martin Logan and Clearaudio to name a few.
I would fancy a demo of the Ethos with a Jadis amp and Clearaudio turntable: I will have to convince my friends at Audioconnection to organise that for me - stay tuned and in the meantime go and roam their website: www.jadis-electronics.com

Well, this is not MY reference system...
But it was certainly very adequate to listen to the new Martin Logan Ethos!
Thanks to the very friendly and knowledgeable team of my friend Adam Carlino at AudioConnection, I think I was the first person in Sydney at least to have the chance to listen to these fabulous speakers.
I will summarise my findings by saying it is the first time I am considering upgrading from my cherished Microphase speakers in the last 25 years...(yes, I know, I am biaised!)
But let's start at the begining:
I currently use a REGA P1 (in its NAD jacket...) with the new RB250 arm(I also have a REGA P3 - vintage 1984...currently on loan to my daughter) and a recently acquired Ortofon RED MM cartridge feeding a NAD 7140 receiver (1984 vintage) used only as a preamp/FM Tuner and then into my Bryston 3B (1994 vintage).
I use a Pioneer DVD/SACD player as a digital source.
I also recently got an iPhone than I am keen to try as a pure digital source.
I have been very happy with this system for many a year and even after visting the HiFi show in Paris, I didn't find anything that took my fancy at a reasonable price.
I have been investigating upgrading my preamp and am considering buying either a NAD C165BEE (#1500$) or a Bryston BP26 with a MM phono stage (#5000$ for comparable features).
So the question is: Is it worth spending an additional 3500$ to get a complete Bryston amplification, or should we spend that money on upgrading the front-end, namely the turntable?
Obviously, it is only by trying the different combinations that you might be able to find the answer, and this is almost impossible to achieve as it would be almost impossible to find all this gear at ONE dealer, willing to spend the time to put such a system together with the hope that one might something out of this exercise.
My ideal and theoritical reference system today would look like this this:
Michell Orbe turnable with Origin-modified Rega RB250 (as the one fitted on the rega P1/NAD555), probably fitted with a Grado Platinum (6500$)
Bryston BP26 with external power supply, remote control and phono stage (4500$)
Bryston 3B power amp
Martin Logan Ethos (10000$)
Total price of the upgrade: 21000$

My second choice would be to upgrade my Rega turntable with Isokinetic kits and arm using Origin Live mods and Grado Platinum cartridge, a new C165BEE NAD preamp, my current Bryston 3B amp and Microphase speakers - that would cost me around 3000$ and would probably satiate my appetite for a better system for many years to come. And that is a 700% price difference!
Will I get a 700% improvement in my listening pleasure???
I let you be the judge...

In the meantime, my current system is MY reference system as I know perfectly all its weaknesses and strengths and this is totally adequate to review other systems against it

BTW, the Martin Logan Ethos are the best value for money speakers I have ever listen to and they provide REAL music and enjoyment:
It was really fabulous to see the expression of surprise and delight on my dealer's face as we listened together to a live recording of "Private Investigations" from an old Dire Straits album called "Alchemy" and my best test record...
It was recorded in 1983 on a Rolling Stone mobile studio and is a magical piece of music, engineering and it was (unknowingly at the time...) my first encounter with Australia, as Brett Whiteley, one of the most famous Australian painter, did the artwork for the cover.
Brett Whiteley in this particular work could be labeled as the Aussie Salvator Dali, my most favourite artist of all times (Album Vertigo VERY 11 #818 243-1)

Just found out that this is now available as a DVD/Blu-Ray album (http://www.mark-knopfler.info/d2010.htm). My birthday is coming soon...
