Tydligen ska det vara en hårfin skillnad på dessa engligt många (t.ex Tyska Audio)trots att JL2 är ett rörslutsteg.
Finns det någon på detta forum som har erfarenhet av Convergent Audio Technology?

THE CAT by Reinhard Wendemuth AUDIO August 2001
THE FANS OF THE LOVINGLY CALLED "CAT", THE CLASS TRADEMARK OF "CONVERGENT AUDIO TECHNOLOGY"; NO LONGER BELIEVED, THAT IT WOULD EVER HAPPEN, THE STEREO-VERSION OF THE LEGENDARY TUBE MONOBLOCKS JL1. BUT NOW IT IS HERE - AND EXCEEDS THE HIGHEST EXPECTATIONS.
In issue 4. 1998 AUDIO magazine celebrated the JL1 LIMITED Edition as "the best amplifier of all time". The Limited Edition version of the JL1 monoblocks , from Convergent Audio Technologies, sounded better then anything that we had ever heard up to that time. At that time it topped the "AUDIO BEST LIST" at 125 points, which in the meantime has been topped only recently by the extremely expensive, 300.000 Mark, "Krell MRA". This rating is especially remarkable since this is a tube unit. With this rating technique, "Audio", is especially careful with recommendations, because of the universally problematic characteristics of tubes. The CONVERGENT amplifier is an exception to this rule. The measured values are far beyond good. The JL2 has practically no limitations regarding choice of loudspeaker. Exceptions are absolutely seldom. Tubes in general have a shorter lifespan than transistors, but are very easily replace. With every "amplifier" one should be prepared that with the rare failure of a power tube, the hardwired cathode resistor will be lost. In this case a good service technician is needed, to ensure a weekend of musical pleasure.
However, the quality of the Russian 6550 power tubes supplied by Convergent, is so great that such problems will be limited to every 2-3 years. Surprises can be controlled with visual monitoring of the tubes. Tube lifespan is recognizable by the deterioration of the silver mirror finish.
Convergent became quieter and quieter since the Drum-role of the "Limited Edition" a good three years ago. In the beginning we still hoped soon to be able to present fans with the price advantaged stereo version of the JL1. But the German distributor had to keep asking us to be patient.
Ken Stevens, president and manager of R & D is not to be rushed. He releases a product only, when he is fully satisfied. Because of this he has lost many potential clients over the years. Other manufacturers constantly bring new or just slightly up-dated products to the market, just to stay in the picture.
Self Competition
Those who waited for the JL2, will now be rewarded for their patience. As advertised the new stereo amplifier not only sounds better, but is also comparatively more price advantaged than the Monoblocks of the JL1, which is widely known for its exotic wound transformer and sold for in excess of 100.000 Mark. This raises the suspicion that Convergent does not want to sell anymore JL1’s and certainly no more "Limited Edition’s". It is hard to imagine a worse marketing strategy. But the people at Convergent are honest. Actually it would not have done any good to hide the quality of the JL2. During the AUDIO listening test, the performance of the JL2, was so outstanding, that it left no doubt as to its superiority.
Just how did Ken Stevens do it? Two monoblocks which share the same housing, but otherwise with the same technical efforts can be accepted. However the JL1 (AUDIO 6/97) did not have the same openness and detail and registered 5 points lower. The answer to the question: what he worked on in that long development time, kept the developer to himself. He only gave the lame reply "many buildingblocks were exchanged for better sounding ones", and that he optimized the already comprehensive, 22 layers boxed transformer to deliver the advantages of pure class A single-ended triode sound..
The JL2 also improves in the area of convenience. Previously the multimeter power supply was simply shipped as a separate unit, it is now built in. This makes the recommended fine tuning after a tube change childs-play.
Convergent does not need any special attention in the set up of the unit to prove its absolute world class superiority. Basically the new JL2, was clearly less capricious than other tube amplifiers, without sacrifice to the certain special something, which is inherent to this species. This certain something makes even lesser recordings a musical experience. In addition the exceptional qualities were not limited just to the mid range, but also on both ends of the frequency spectrum JL2 underlined its unmistakable superiority. It was unbelievable how well she handled the not at all easy to control reflexsystem "Wilson Watt/Puppy 6", with regard to precisely controlled basses. In fact how wonderfully the JL2 harmonized with the legendary Wilson boxes, is proof of how much less critical it reacts to the selection of the speakers, in comparison to other tube units. Amazing also is the strong sound of the clarinets, without the usual mistake to cover the sometimes sharp sound of the instrument. Just as the Spanish say of their famous artist Diego Velazquez, to have the ability to paint in the air, the Convergent JL2 is equally capable with its three dimensional and lively sound.
Happy those who can obtain one of these rare units!

| lär ju bero lite på vad man vill uppnå också nu vet inte jag vad JL2 har för watt men det lär inte va i närheten av MRAS och 1000w klass a med bibehållen ljudkvalitet är det inte speciellt många steg som fixar |

Ekman> JL2 har 100 triod watt klass A och tydligen så tycker dom att den är i närheten.

| beror ju som sagt på vad man är ute efter och hur högt du ska spela osv 2*100w lär inte alltid räcka till på samma sätt som MRA sen så kanske dom är hyfsat lika vid mindre effektuttag men det är ju en annan femma |

"The JL2 has practically no limitations regarding choice of loudspeaker. Exceptions are absolutely seldom."
men visst för vissa högtalare kanske det är skillnad.
Vi får väl helt enkelt testa dom  |

| Jag vet inget om slusteget men deras försteg SL1 Ultimate tillhör, enligt många, bland de bästa som finns. Jag har inte hört den men skulle gärna vilja, då den innehåller ett mycket bra riia steg. Pris 6000$. Med tanke på detta, så är slutsteget säkerligen mycket bra. |
