CES 2012 - (au temps) Jadis 03/31/2012
![]() Jadis: the first amp JA80 Jadis has been at it since 1983 - unlike Samsung, they are not a newbie at using valves! Andre Calmettes, the founder, invented the JA80 at that time (hence the name, I guess...) Although certainly not looking Danish, this product produced such an extraordinary sound that it became an instant hit. Perfectionism is certainly a reason for its success: The valves are tested and paired before being used in production, components are carefully selected and have been improved over time, and the "piece de resistance" (or should I say "no resistance"...) is the output transformer produced in house and capable of withstanding 2500 watts without distortion! Currently, the most powerful Jadis amp is rated at 350w, so far away from that specification. Since then, the product range has grown to include phono stages, preamps, amps, DACs, CD players and cables. And the look! well definitely matching the internal beauty - check the wiring: magnfique! Jadis was one of the few French companies present in Vegas: good on you! Check the photos below Add Comment My first Hifi system 05/22/2010
When I was at Uni - and still living at home, as most students did at that time - my passion developed further, and I was keen to use my new found knowledge - I was studying for a BSc in Electronics - to build my first hifi system. Coincidentally, my sister and I were gifted a DUAL 1219 turntable for Christmas, so I decided to get down to work. My budget being quite limited, and having settled for a full range high efficiency speaker and valve amplifier, I went shopping... I was confident I could design and build a solid state preamp, so I did, but for a strange reason, I didn't feel confortable designing the amp from scratch, so I went and bought a kit from Cibot Radio and assembled it myself, crossing fingers that I would not put the house on fire on first power up. As I am still here to tell the story, you have your answer...an added bonus though was that my room was always a couple of degrees Celsius warmer than the rest of the house, as you wouldn't switch that amp off, would you? It was quite an ugly thing in military green lacquered perforated metal for the cover, but the sound...ah that glow in the valves transcribed itself in velvet music! Even my crude preamp could not ruin the sound... For the technically inclined, it seems that this was the valve configuration: 2xel84;2x12ax7;ez80, but it is a while back, so I can't be sure. If anybody has more information let me know via our contact form or the comments function. Thanks in advance. Now, for the speakers, I used a full range 17cm drive from SIARE in a closed box made of MDF and filled up with wool bed covers kindly given by Mum... At the time, Michel Visan was the technical director of SIARE. He ended up starting Davis Acoustics, who continues to make some full range speakers inspired by the ones he designed for SIARE - see photo above. We ended up quite good friends and I would use some of his paper cone woofers in future designs, but more on that later. I have never been a fan of Kevlar which started to be the rage in the 80s, when both Jacques Mahul at Focal (ex technical director of Audax and arch rival of SIARE, and Michel Visan at Davis Acoustics introduced drivers using this "space age" material. I still believe paper cones have the ability to sound better than any thing else for the midrange, as they respect the timbre of instruments better. The whole system was housed in a white laminate "structure" with the amp on one side, the preamp and turntable on the other side to avoid picking up rumble from the amp, a desk in the middle and the "legs" containing the speakers at the top and some space at the bottom for records stored vertically (bien sur...). I will try to find a photo from my parents archives or else, I will make a drawing of it (but do you really care...?). This system kept me happy for quite a while, until I came across the Elipsons and Supravox. But that will be my next story. And it started, I guess, because there was always music playing in the house, mum played the piano, my parents used to dance in the living room to the sound of an old gramophone playing LPs but also a very large collection of jazz 78rpms . And one day, when I was 15, Dad surprised us with one of the most up-to-date piece of technology of the time: A Grundig Stereo console and black & white TV ( 819 lines SECAM, the now defunct French precursor of HDTV), complete with a tube receiver and 2 elliptical bicone speakers, all housed in pure 1950s faux lacqured mahogany. It would have cost an absolute fortune, and knowing Dad, it would have been a decision carefully undertaken, with Mum financial blessing. This piece of equipment has been in continuous use from around 1965 until the 80s, including a 4-year stint in Mexico City and back, and then the cabinet was still home of a new transistorised hifi system bought by Dad's colleagues when he retired, and a new colour TV suitably replaced the SECAM unit, obsolete by then. In 1984, I presented him with a pair of speakers of my own design. More on this later... It was our first television, and we had had a telephone for just a couple of years, only because Dad was on the road for work most of the week. He was driving around a large territory centered on Tours to inspect large computer installations and ensure their proper performance and maintenance. He ended up being the General Manager of that Division for the whole company for the last five years or so of his employment before retiring at the tender age of 57... | AuthorBorn in France, well travelled, relocated to Sydney in 1997.
