I've tube rolled about 20 different 6dj8 tubes in the last year, and I've learned a few things....I've yet to meet a Mullard I like, they all have no top end extension to my ears, and some are seriously lacking in dynamics and initial transients. I've tried the Siemens Cca, both the earlier Halske and later Rohre and while incredibly detailed I found them a little thin also. In fact I found the Siemens 7308 tubes to be superior! Be worth your while to try them. I am currently trying out Amperex stuff, the PQ white label seems very impressive so far, but its to early for me to comment yet. The tube for you is the Telefunken Cca. A beutiful soundstager with incredible dynamics and detail, with just a hint o wamth. Its my favorite 6dj8 tube, followed by the Siemens 7308. Be warned, they are hard to find and pricy! (expect to pay between $300-$400 a pair NOS)
