EL34 comparisons please

Hi, I have a Dynaco st70 which is stock and has the bloomy midrange sound that I like with Jazz. I most recently bought a Conrad Johnson mv52 el34 amplifier which sounds nice and I was thinking of trying some new el34s with it looking for more exaggerated midrange. Any suggetions would be great. Speakers are RSIII Infinity's and the tubes that I am using now are vintage Sylvania.
Thanks,
Guy

the cj is given to accuracy over bloom with any quality tube....don't mistake that dynamic sound for bloom. on the other hand, the st70 is(along with the marantz 8b,one of the most magical push/pull designs in history.

I have 2 sets of CJ m.blocks.The 5s and the 8xs (Both all triode)I use and love the Seimens. I have a new set of Svets---they ain't the same for sure. Other than the fact that I'm talking about 32 of them el34s I would try some Mullards.----But everybody wants 250 each tube.--- And I've never seen an add for 16 Mullard. Not that I have 4k to spend on tubes. The Seimens I get for 20 ea;If I buy 20 of 'em at a time.--- There's an old thread in which Albert talks el34's, I forgot what his fav.was in that thread.---Mine was the same then as it is today.

Interesting. I just today rolled my EL34 JJs for Svetlanas. They already had 72 hours burn-in so in about another week of serious listening I might have something to say. I can say that I rolled my KT88s from JJs to a set of well-used Svetlanas and the improvement is much more than I expected.
