[quote user="jessie.dazzle"]I completely agree, and will use the driver that sounds best with a 40Hz exponential horn. I have both versions of this driver, and have listened to them both in an A/B situation, out of the horn; I remember noting the...

[quote user="jessie.dazzle"]I should mention that with all the wonderful things it does, the L2 (preamp) definitely deserves a fresh pair of 12AX3s and a 6C19P. (I have not changed them since starting work on the horns... all tubes are exactly one ye...

[quote user="jessie.dazzle"] I don't have a problem with what Lamm has done in offering the ML3 (ignoring the price)... If I have a problem it is more related to how the product is being represented. Representations aside, depending on how it sounds,...

Stitch, even though you are not wrong what you say but I do
not think it has a direct relation to what I call the "worse". My angle
was different: the demise of SET concept if the amp increases some rational cost
level. The cost of LAMM electronic...

[quote user="jessie.dazzle"] Scrolling down to the images of the Lamm ML2.2, I see something that intrigues me...
Four ML2.2s are used to bi-amp the Verity Audio speakers; I didn't know they could be daisy chained by using both the XLR and RC...

You may remember my first impression of ML2 was its "organizing". And you may also remember my saying that SET just "allows" the signal, including its dissipation.Not to "sell" Milquiades, but how (other than multi-channel and bandwidth limitin...

Well, the Q5s were everywhere when I was trying to find big amps, and they really have no chance to move me. Even to do what they might do would take maybe 500W SS, yet Harley thinks he hears them at their best with the ML2.2. Then again, I suppose...

We should always remember that VL designs by design, rather than with his ears. While I would guess it's OK to sub 950s for 935s, at the same time I'll bet VL has taken into account ESR and other parameters that the average capacitor-swapper mi...

Hi, WojtekAs soon as you find a sonically-comparable amp that's less trouble, please let me know. At this point it does appear that a certain amount of vigilance is part of the price of admission.Of course I was (mostly) joking about losing the...

[quote user="skushino"]So next week I will broaden my playback experience by adding my new 90wpc PP mastadon, and Romy's approved Lamm ML-2, in addition to my current DRD-300B amps. And as a personal favor to the readers at ...

Jessie,
A few hints. If you are moving from Parsifal/Encore and LammM1.1 world into the world of SETs and Horn then do not be in hurry to commit yourself and do not create to yourself artificial addictions.
When I talk about artificial addictions I...

This post is the phono-relevant part of info carried over from my recent "better tubes" post in the ML2 thread.Subsequent listening has established that the electricity during that session was better than I'd thought at the time (dammit!). ...
|

Generally, the ML2 sounds fine after >45 minutes of running, pretty much as any other tube amp. Also since your Lamms were sitting for 5 years without working you would need a few weeks unit your Lamms reach a nominal operation condition. The well...

"Borrow somewhere Lamm ML2.0 to drive them (very critical)
and you with those old and crappy JBLs will get a quality of Sound
that will be more superior than anything else about which “The Absolute
Sound” has wrote for the last 10 years, par...

HE, you've gotten a long run so far without anyone asking if you've read the site. Have you? There are long threads on the Lamms and the Lowthers that might offer you some food for thought. One thing I would recommend is playing with the ML2 "plat...

He did note that the ML2.2 uses a different OPT, and also that it uses "less feedback" than the ML2.1 (which AD owned for several years). I wonder what this means, "less feedback"? Why would Lamm mess with that very effective scheme? Does he just ...
|
|
Well, I never seen it happens but who know – that might be if some use “violence” on tubes. The sad part is that to replace these sockets is difficult. I have replaced in ML2 the 6C33C sockets in ML2 - it was easy but the 5651 are PC board-mounted an...

I would not generalize sound belong a topology. What we call SET or PP sound are juts characteristics of bad SETs and bad PPs. Even if we do generalize then it is not my observation that SETs “slightly electrify” sound. Rather they sound soften ...

[quote user="Romy the Cat"] It did not last long….
Just a couple days back I was thinking that I will live with my current lower bass for a while and now I feel that I will not. I do not feel that my current ULF is wrong. In fact I feel that ...
|
|
Be careful with those 5751. ML2 became unstable with 6db more or less (I do not remember already) global feedback. Lamm told me a long and big story how critical for ML2 to have the global feedback of exact amount and how “properly” the feedback is i...

Today I replaced the problematic pair of Chinese 7 pin sockets on one of my ML2s. It looked like they were replaced at least once before, and that my job is at least the second set of replacement sockets, so three total counting the OEM pair. There...

Paul, there is a number of inaccuracies in your post.
[quote user="Paul S"]Lots has been written already about tube replacement, but I want to mention my recent experience when replacing the 6C33C output tubes (V2). I had the previous tubes in...
|
|
[quote user="KOTriode"]Romy, in the contrary, it is very unfair to compare my 845 amp with the 6C33C. The main reason is the 845 amp used the best output/interstage transformer available, while the 6C33C's output xformer is pretty good but far from b...
|
|
[quote user="Paul S"]I got new 6C33Cs for V2s from Lamm because no one else wants to match them, let alone match them for gain…[/quote]
There is no meaningful mutual conductance or bias matching for 6C33Cs (in context of ML2) besides gain matching, ...

Jessie,
Actually the tendency of manufactures to isolate ground becomes almost common among any more or less serious manufactures nowadays. The main’s ground is so polluted in US hat it is scare… or even dungarees. I remember a few years ago when I...

[quote user="George"] I am not quite understanding part of what you say:
"It is very difficult to make a generalization about it but generally this quite “large bloomy space” will be a space equal to, I would say, 1/8-1/12 of the room ...

Jessie,
I was trying to evaluate the gain of my amplification in respect to larger room and again was thinking about your case. I think something that you do it not correct. You are complaining that you have not enough gain in upperbass, but I...

I do not know Bud. I report only what I see and I believe in what I experience. Almond all SETs that I personally have heard the Lamm ML2.0 had the widest subjective frequency range. I did measured how ML2.0 clip and it was at 18Hz at the bottom and...

[quote user="Romy the Cat"]To simplify everything: the Melquiades was at attempt to make two stages, capacitor coupled, no feedback SET, having the cathodes sitting on ground and using the unique 6E5P as a driver. My selection of output tube was beca...

Well, it looks like it was what I had but until you reminded it I did not recall. The key is that it was not with my amps bur with the amps of my local guy. You see, his amps were sitting for a long time and the sockets wend bad, rusty. In your case ...
