Best EL-34 Amps?

Hi Pubul57, I have not tried any of the other tube variants in my Cayins. I am now curious though. I stuck with the EL34s given their reputation and BobbyP's recommendations. Interesting comment on the EL84 lacking power. In my Cayins I get ~38 watts triode and 70 watts ul. I can switch it on the fly and the sound difference is very subtle. I had expected a more significant change between the two, but it is fairly close. I'll usually go ul for HT movies and triode for dedicated listening.

The RM10 is 35 watts and it is enough power on its own terms, but when you put the 160 watt RM9 in the difference in power makes a difference that is preferable - I was attributing it to the power difference and the fact that it looses no wattage as the impedance dips (which should not be much of an issue with the Merlins). But give the price of the RM10 with the EL84s I would say the EL84 is a very nice sounding tube in a well designed amp - great midrange tonality and I think more resolved than the EL34. There is another member who is doing the EL34/KT88 comparison with his RM9 as well (and Merlin speakers) and I'll let you know what his impressions are when he has some time for the comparison. I won't speak for Bobby other than to say he proabably likes the EL34 for its midrange beauty and his speakers don't depend as much a lot of bass drive and control from the amp to produce well defined, controlled bass (why they work so well with tubes in general).

well, i've heard the manley snappers and a few integrateds.

but i must say that "under the radar" EL-34 amps are those sold by Synthesis (Italy) called: The Theatre

they are 70watt Class A monos.

i think they sound fantastic. there was a pair available here not too long ago for a steal of a price.

no one knows them so they are pretty rare here in the US. they are semi-common in Canada.

they sound much like drawn butter (that's my friend's quote, not mine). liquid smooth.

Those RM-10's sure don't last long when they're put up for sale here. Roger has been able to get roughly twice as much power out of the EL-84 versus other designs using that tube. My speakers were voiced with an Atmasphere S30, so the RM-10's power output should not be a problem. If I can ever grab a used RM-10 I'd love to hear what it can do in my system.

If they were voiced with the S30, no doubt they will be driven wonderfully by the RM10s, but as much as I love my RM9s, it is hard to beat an OTL with OTL friendly speakers, but very nice for a high quality change of pace (which is why I keep the RM9SE) - both Music Reference and Atma-sphere are made by superb designers. Are your speakers sensitive enough for Music Reference's 5 watt SETs? If so that too would be worth trying, never heard anything by Roger Modjeski that didn't sound great, was well built, and would prove to be ultra-reliable.
