Will a pair of Manley tube amps be a good match for Martin Logan ESL 11A's?


I have been looking into the Manley power amps to drive a pair of Martin Logan ESL 11 A's. From Manleys specs they report a speaker load of 5 ohms is recommended. The Logans are rated at 4 ohms.

I was about to provide the same counsel as mijostyn above, and am gratified to read it here before I posted it. Roger Sanders excellent white paper on tubes vs transisters explains a lot.
My .02 is that you probably can pair Manleys with the Martin Logans, but at what cost? Which model in the range? I think you might find the Magtech equal or superior, at a very reasonable cost.
Two transformers is really uncomfortable for my brain.
Why the two transformer phobia here?

Years ago, I auditioned a pair of Sound Lab U1 speakers with three amps: Atmasphere MA1, CAT JL-2 and Parasound JC1.  First up was the JC1 and the sound was boring.  Had this been the only amp I heard that day, I never would have bothered again with the SL speakers.  Next up was MA1 and the sound was truly beautiful.  Dimensionality and harmonic structures was truly incredible.  The JC1's were absolutely broken in comparison.  Last was the JL-2 which did not have quite the lushness of the MA1 but with the CAT came far greater dynamic contrasts and a bigger bolder presentation.  The choice between the 2 tube amps was not easy, as both had excellent tonal coherency with the MA1 just having a little more presence in the lower mids.  But I went with the CAT as it controlled the SL speakers with incredible authority and I knew I could get some of that MA1 "magic" back with the right preamp and tube rolling efforts.  And ultimately I did with Aesthetix and later Aria preamps.  So the whole notion that transformers are "bad" was clearly disproven to me that day.

I still suspect that the VTL or Manley amps might be outstanding here as they too bring on an outstanding 3D quality that might work beautifully with the ML's.  If you want to consider SS amps that won't break your budget, look for a good deal on a BAT VK 600SE.  I have a pair of these in mono configuration and they are outstanding with the Sound Lab A1s.   But I gotta believe a single VK600SE would be plenty.  The result is not at all like I heard with the JC1's.  Why the obsession with the JC1's in these forums is beyond me!

Oh, and I did hear the RM200 amp several times at a dealer and every time, his system sounded wonderful.  So this too may be an option, but it might run out of steam when you require a louder volume setting or are in a big room.

Again, call VTL, Manley and ML to get the advice on these exact products and not be focused on white papers of other products.
jafox, I have listened to JC-1 extensively. You can not find one even a little iffy review. They are all dramatically positive. My review is exactly the same. The only amp I have heard on ESLs sound better is the Pass XA 200.8 and I suspect the Atma-Sphere MA-2 is up there also. My assessment is that your review samples were hooked up incorrectly. It would be the only way you would hear something as bad as you relate.
I also understand that SoundLabs was using JC-1s in it's sound room. Transformers have all kinds of problems associated with their use. I am not educated enough to fully understand the issues but you can google this and like me you will probably be dizzy after the first page. The one I understand for sure is saturation. When the transformer saturates you hit a brick wall. It is pretty much like an amplifier clipping. But in the end it is the sound you like that matters. In my system tube amps can sound lovely but they have all lacked the dynamic punch necessary to recreate some music. This is only on ESLs mind.  
bdp24, you know darn well that Jim Strickland was the first designer to put that stunt. I happen to know somebody who uses Jim's high voltage amps on his own ESLs:) I would love to see how Roger tackles this design. 

@mijostyn, I’m not sure of the year Strickland and Beveridge each introduced their direct-drive ESL (the first Beveridge ESL, the Model 1, was invented in 1965), but I do know Strickland discontinued his amp and went with a transformer because of reliability problems in the amp. Modjeski says he has repaired a few of them, and found it’s design weaknesses, designing a mod to correct them. One of his services is to rebuild the Acoustat amp, for which owners send him their broken ones. Roger was hired by Beveridge to solve the reliability problem in his direct-drive amp.

Roger worked in an electronic repair shop in high school, and learned how NOT to build an amp. If a circuit calls for a 2w resistor, he uses a 20w. Trouble-free operation is a very high priority for him, in contrast to some more widely-owned high end brands who put other priorities first. When I bought my first ARC electronics, turning on the SP-3 pre-amp for the first time blew a resistor. I couldn't believe it. My dealer (Walter Davies, who co-developed his patented Last Record Care Preservative---which is NOT Freon ;-) put it on his workbench and had it up and running in a coupla minutes). That was a long time ago, and Bill Johnson did eventually learn the lesson he should have known long before (he too started his career as a repair technician). At a seminar I attended in the 1990's, Johnson talked about how a batch of bad parts almost put ARC out of business in the 1980’s.

pvmike,

One assumes having posted the specs for the Manley 500 monos, these are the amps under consideration.  I've not heard them, but am a long time owner of the Mahi Mahi and can attest to them being scary fast and able to handle many different speakers with ease within their power limits, about 40wpc, 25wpc triode depending on the speakers.  

Manley tends to over build and invests heavily in power regulation.  I would tend to believe these monos would handily power anything thrown at them.  I took a pair of VTL Tiny Triodes to a shop once and powered their smaller ML speakers and they were shocked at how easily they drove them, how smooth they sounded and how quick it made the MLs.

I would not back away from the Manley amps.
