Best EL-34 Amps?


Looking for votes/recommendations on the best available EL-34 mono-blocks... I have tired many different amplifiers over the years including 300B's, SET's, EL-84's, 6550's, all manner of solid state (nasty!) and haven't found anything that bests' my VTL-125MB. However, they ain't as young as they used to be and I have always wondered if the magical pair of EL-34 mono-blocks are out there and have just slipped my attention. They must be very quiet, since I use extremely sensitive Klipschorns (104db)...any noise is ruthlessly revealed...

Mr Magfan- Exactly! One of the most successful tube amps ever(the Dynaco ST-70) used EL-34's. The excellently designed and executed output transformers made that amp. They can actually sound quite a bit like music with some minor upgrades/tweeks, and the right tubes. Mr Stickman- I would have to second(third or fourth as the case may be) the suggestion of the AES Sixpacs. Dennis Had is an excellent designer(I'm using a pair of modded SLM-100's to drive my mains) and did a really good job on the Sixpacs. A review: (http://www.soundstage.com/revequip/aes_sixpacs.htm)
Thanks for the kind words, Mariusz! I wish I was with you guys yesterday, as John Rutan is a good friend of mine, and a real honest to God good guy.

I'm happy to hear you were able to hear the Music Reference. Those amplifiers are pretty shocking in how musical they are, aren't they? If it was the one using the EL84 output tubes, the tone on that amplifier makes me wonder why we audiophiles jump through hoops searching for more.

And, you are spot on with the Jadis. Possibly the most eye opening midrange I've encountered was when I retubed my JOR with JJ E34L tubes. I was so taken with it, I then came to own a Jadis DA30 and DA60. The DA60 being perhaps the finest tube amplifier from top to bottom I've ever been around. Along with my loudspeakers, I believe that amplifier is a lifetime purchase.

One mistatement I made about Consonance was regarding the 15th Anniversary products. Intead of "On several levels, they are the best tube products Consonance has ever put out.", I meant to say best PUSH-PULL tube products. Though it certainly has its limitations in terms of power and low frequency performance, the Cyber 300B PSE is the best tube amplifier in their stable in my opinion.
hi joe:

thanks for your timely observations. i am looking into a cj mv55 and a dynaco stereo 70. they may offer a bit more of a euphonic character than either the quicksilver amps or the consonance amps.

i am somewhat disappointed with many tube amps in current production. they don't present a classic tube sound, like the older mcintosh, conrad johnson and audio research amps.

the exception is the wavelength amps, which are very expensive but lean more to the vintage than modern tube sound.
Mrtennis, based on most of what I read from you over time, I would think these two products would suit you very well.

I am currently playing with my own Dynaco ST70 right now that I just built over the summer. It's an incredible product to say the least. Especially, in light of the pricing.

Replacing the stock Sovtek 7199 with a pair of RCA yielded more of an improvement than I've ever witnessed with any other tube component. This change alone raised the letter grade I put on the amp from a C- to a solid B (borderline B+).

For less than $1000, you get an amplifier that isn't the last word in low frequency response, but otherwise pretty much sounds as good as anything else produced today. In fact, I probably prefer its midrange to any Consonance push-pull tube amplifier. I need a bit more time with it before I can say that with 100% confidence, but I probably won't be able to fit it in until after RMAF2008.

I haven't experimented with rectifier tubes yet, but, from having a very weak one in there initially, which caused my readings to be way off when I checked the various voltages through the amplifier, this tube is of critical importance as well. So, I will seek out a good older tube to replace the EH 5AR4 and see how much the amp can put out in bone stock form before making the mods I intend to down the road. Overall, it's been an incredibly fun and illuminating project for me.
