Howdy, RJ!
I am a bit confused. I thought you have been using tube amplifiers on your MLs?
Where are these solid-state amps coming from?
(I am curious because at audio shows and dealer demos I have heard various solid-state amplifiers driving various Martin-Logan speakers many times (including the Statement E2 once and the Neolith at least three times), and I have not once in my entire life liked the sound of a system which combined solid-state amps with ML speakers. Regardless of the particulars the combination just does not work for me.)
Big WOOF WOOF from Ventura County, California!
G'day Ron,
Great to hear from you. Trust all is well at your end of the woods... and those Pendragon's are playing some fine tunes!
Definitely agree on SS not being that great on stats but that again depends on which type of SS gear and how it's used in the primary role of amplification. I've found combinations from Pass Labs, CH Precision, Solution, Momentums, Relentless and more recently Dartzeel to be outstanding when partnered with all tube front ends. That hybrid combo sounds marvellous, drives the notorious impedence curve found on stats with ease, yet is equally outstanding on tubes, I guess it's a personal preference.
With SS, in my experience I've found that since they don't have output transformers, instead they drive the low impedence of speakers directly. This may or may not be a good feature depending on the power supplies and how reliable they are. All of those I just listed, I've had extensive experience with them and know for a fact they deliver what they're capable of 110%, no issues. However, at the same time there are many "high powered" amplifiers that simply run out of puff... mediocre power supplies and high watt ratings are rendered useless. It's all about the current capacity and SS devices have this high current required to control and grip difficult loads.
Having said that, now tube amplifier design has come a long way. I've found that especially now having top notch output transformers that provide the coupling interface between the tubes and speakers, allows the tubes to drive and control difficult loads along with the added high current provided by these top quality transformers. Tubes as you know possess low current but high voltage, so unless the output trannys are designed extremely well, it will be difficult for most tubes amplifiers to drive stats properly. Again power output means nothing much.
In all brands of tube amplifiers I've used, owned and tried in the past, some good, some not so good, others ok and one in particular that has always impressed, not flinched ever under difficult loads is CJ. They're output transformers and power supplies are outstanding!
My good mate who has the mighty ML Statements used to drive them with a full array of top line VTL/ Manley Labs amplifiers. Then he changed over to the Momentums and since lately the Relentless monoblocks which he still uses as the primary amplifiers. On the tube side of things, since lately he's using CJ's ART300's along with the Momentum preamp, and I must say this is one extraordinary combination! It's just an awe-inspiring experience, more so on the Statements as well as on the CLX's full range. This is one combination I would certainly like to have but finances don't permit atm. That's why I've been slowly upgrading and modifying my monoblocks to get to a certain point where they can deliver a slightly higher Class A bias, thus being able to fully grip the CLX's and drive those triple stators.
To answer your question where did all these SS amps come from... well no, I haven't changed from my CJ tube amplifiers, I never will. Since lately what happened was around Jan I sent the monoblocks for a final SE upgrade and in the meantime I got a chance to experience some great SS amps with the CLX's. Then just a week ago when the monoblocks returned, all was fine and wonderful until a hum started happening from the right channel, and in addition to that, an unusual loud static pop whenever a light switch was activated across the hall. This aggravated me big time, so once again called in the experts to source the problem. After a whole day of searching, and seeking out the issue it turned out to be the right channel monoblock. So that's now gone back for a check up...
The monoblock should arrive back by mid March, until then here's another mighty fine SS design by CJ that I'm really enjoying as I'm typing this reply...
Cheers Ron, a big woofty woof'n!
Oh! I forgot, enjoy those fine tunes!
RJ
