Effectivement, il y a un pont de diodes à côté de chaque transfo et une diode à côté de chaque régulateur de tension (LM 317..)
Je vois que tu as porté ton choix sur des Nichicons de gamme FW. Dans quelle gamme as-tu choisi ceux de 100uF 450v.
Perso, je voulais partir sur la gamme KA.
Les ecc88 ne peuvent pas se monter dans les SFD à cause de leur tension de plaques max?
Ouah, 8 tubes E88cc dans le Ref1, ça pique. Bon, c'est 2 de moins qu'un CJ Art 2 et 4 de moins qu'un SFL 3 mais cela commence à faire.
Je viens de lire le banc d'essai de Ref 1.
J'ai le même ressenti entre le SP16 et le PV14, différents mais tellement proches, c'est difficile de fait un choix mais j'ai une petite préférence pour le CJ.
I suppose it would be only natural to compare the Reference 1 to the Conrad-Johnson ART, even though the ART costs about $5000 more. I did so, but the results were confusing, to say the least. After having lived with the ART for over six months, I would have said that it and the Audio Research had very different presentations. The ART, I would have said, is relaxed and sumptuous—a rear-of-the-hall, everything-blended-just-so kind of sound. The Reference 1, I would have said, has a closer, slightly lighter sound—not in-your-face so much as direct and forceful.
And that's true, sort of. In a matched-level comparison, the two sound a lot more alike than those descriptions sound. Awfully darn similar, in fact. Frustratingly so.
But in extended comparisons they revealed personalities that differed ever so slightly. The ARC had more solidity and control in the deepest bass. I think. No, really, I'm pretty sure it did. The C-J had, again, an ever so slightly purer, more extended top end. Overtones seemed to linger in the air somewhat more effortlessly.
And, yes, I think the C-J had a slightly more softened, slightly distant, somewhat darker perspective, while the ARC somehow seemed more sunny and close. But I'd really hate to have to walk into a room blindfolded and identify either one within seconds. These are, after all, both state-of-the-art tubed preamplifiers, and when put to the test, they sound a lot like music—which means they sound a lot like one another.
Bonne pioche pour le ML 380S aussi...
