Old Question, any new responses? Logans and tubes


Can new tube amps like Yaqin, music angel, ... pumping out 60-75 ultra-linear, 30-40 triode run Martin Logan SL3?

Will a mono dynaco 70 tube due the job for a ML SL3. I would get two, one for each speaker. I know they are 35 wpc but heard you can mono them for 70 wpc.

Thanks
Lostbears named a amp I completely forgot about as I had cary Slam 100's on the m2's with 95 watts triode;excellant sound but just was not enough to really control the panel when volumn level was increased; although this is a very good amp;if you can find one with the ultralinear switch which increases power to 160 watts it would be a amp to consider;I also think going used gives you a lot more amp for the money and on resell you don't get beaten up to bad with the $$$$.
What about Jolida Hybrid amp. They are rated at 100wpc, have tube pre and ss power amp? Any thoughts on this route?

Thanks


I have owned my SL3s since 1997 and I have tried a lot of different amps with them. They really need 90 to 100 wpc to be driven well. I have tried a 50 wpc amp and they sounded all closed in and a little distorted. They were pushing the amp into clipping. I had a pair of Cary SLMs in my system at one point and that was a nice match. A little more on the tubey side than my ARC. All point to point wiring. The Manley amps are also really nice sounding amps. I have also tried Solid State amps like the PLINIUS SA102. While not bad sounding I really prefer the SL3s with tubes. I also think they sound better with a triode design. My suggestion would be to consider buying used. All the manufacturers that have been mentioned have made some great amps. They can be picked up used for a fraction of the original cost.
The challanger amps I think start at 115 watts then progress to 180 watts triode power.
The manleys,vtl, and quicksilver amps I have seen average in the 90 watt range and then progress;there are models with lower power but I personally would not consider anything less than 100 watts to really drive and control the panel of the SL3;maybe a person with this speaker experience will respond to your post as I can only relate the my m2's which are a full range panel which would be similair to the logan cls speaker.
Thanks Rleff but are the amps you mentioned good in the 50-70 watt range or do i need their powerhouse models (if they have) in order to run logans?
I would think the higher powered amps woule be a better choice;Manleys,vtl's,quicksilvers,and Audiovalve would be on my list.
I run Audiovalve Challanger 180's on my soundlab M2's with excellant results;what is nice with these amps is it allows tube mixing and matching as it is autobias.(el34,6550 and kt88 capable)a nice option for custom sound if you want to play.
I would think the SL3;s would be a good match at least on the panel portion.
Does anyone else have 1st hand knowledge about these new type tube amps? I appreciate Stereo5 input. However, need more info from AudiogoN nation.

Thanks
Last year I bought a Yaquin amp. I had it all of a week and got rid of it. The build quality was junk. Sure, it had a thick face plate, but once you looked inside, the shortcuts were obvious. It didn't sound that great either. Just thought you should know.
I agree with Lostbears. The amps you mention will drive the SL3's, but not very well. If you listen at a low volume level, you would be fine, but more power and current is always better with Martin Logans.

You need around 100 wpc to drive the SL3s well. I was using a ARC VT100 to drive mine and it was a good combination. I tried a VS60 and it would not drive them at all. I have also tried bi amping them with two VT100s and this made an improvement over the single VT100. But in the end I did not feel it was worth all the extra tubes. Currently I am using a ARC Ref 110 and I am very happy with this setup.
