Positive Feedback published David Robinson’s review of Lamm M1.2 amplifier.
http://www.positive-feedback.com/Issue34/lamm_1.2.htm
Frankly speaking I do have interest to see what people might say about Lamm M1.2. Not that I care about a review’s ob...

I regularly visit 6moons News Section that lately became quite good sources for audio news. It is same that Srajan not willing to share the news in RSS or compatible format, anyhow…

I went recently at the Soundstage.com site and read Marc Mickelson’s comments about ML3.
Marc Mickelson had an “honor” to make my site in past:

LaurentAlthough I have whined that the ML2 requires "tweaking" to get its best, the truth is that it is closer to the dream of acceptable "plug and play" performance than any amp I have ever used. Which is a long preamble to saying I am hardly an ex...

[quote user="Paul S"]I also wonder about the supposedly simple but ever mysterious procedure for matching 6C33Cs for gain. Presently, my amps are ~ 2 dB apart.[/quote]To do gain matching we need a way to measure gain. To be precise, we need to measu...

[quote user="George"] Even though a PS Audio and others create a perfect AC sine wave this does not seem to be the answer, even for low draw front end components. It seems that some type of problem is still coming through. [/quote]

Hi Romy,I am very interested in what you have found out about the 6C33C tube lifetime because I am using a pair of Silvaweld OTL tube reference (their name for them not mine) amps that use 4 x 6C33C-b tubes per monoblock (so a total of 8). Thes...

[quote user="Romy the Cat"] Good question, HookEm. I would say my answer would be 2, “Any single driver back-loaded loudspeaker in general”. Do not get me wrong, driving your, or any other single drivers would do fine by ML2.0 and you will be able to...
|
|
[quote user="HookEm"] Actually, I would prefer moving towards a more permanent solution (for practical, and frankly, economic reasons); and if that means moving away from the single driver (yellow cone), so be it... Now if having the subs in place wo...

Regarding Mike's observations: Indeed, there might be more There there than he intended.He might have said anything at all, but he seemed to get stuck on the "micro-management" issue.Sound familiar?Who would be surprised if the ML3 turned out to...

[quote user="jessie.dazzle"] Make sure the power switch is off, and connect the power cord.[/quote] Unless you are a republican. If you are then you need to change voltage with power switch on and power cord attached.

If Lamm had actually used the larger 950s in my unit I would probably be less curious about it, but for mine he used 10uF 935 couplers with small 950s for bypass (... I assume they are bypass caps...). Hard to imagine 10 uF couplers would not have a ...

Merlin here is the Stereophile measurements on the Lamm ML2.1http://stereophile.com/tubepoweramps/1004lamm/index4.htmlAs you can see the rise in distortion vs. frequency shows only a small rise in distortion even down to 10Hz. This is an indica...

[quote user="AlexBerger"]I tried Amperex ECC83 "Bugle Boy". They sounded bad in the EAR RIAA. I like more modern Amperex ECC83, Holland made with orange-red prints.[/quote]Yes, the Amperex "Bugle Boy" are horrible tubes. They have huge publicity amon...

[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...

The cool thing is how Lamm figured out how to get one's attention off the window, albeit, apparently, through a fairly didactic program of "organizing", "correcting" and/or "mitigating" certain information he realized contributed to that particular d...

What speakers are your using? The “4R at about 80 Hz before going back up their average 8 Ohms at 30 Hz” is not good for SETs. I prefer to have 16R and do not let it to drop below 12R. Lamm is quite fixable with loading, probably because ...

Honestly, we're gonna have to start calling you Romy "magnetar" Bessnow if you keep changing your mind like this...*My S2s all seem to measure completely differently, will have to get some more accurate and careful measurements done I think with...

[quote user="Paul S"]Yesterday a nice fellow drove off with "my" Lamm ML2s. Now it is really sinking in: How will will I find anything else this good, along with more power?These amps were like a PhD in sound, what might be done with hi-fi. Yes, I ...

After swapping all the tubes between the left and right amps, the cycling bias current issue (mentioned here in a previous post) seems to have settled.I now have another question, which I hope other ML2 users might answer; first the context: These am...

[quote user="Romy the Cat"] If you have a chance to hear Lamm ML2.0 then try them... [/quote]I wanted to do that, but they are so rare and I found nobody to visit. But honestly, I am not so fanatic, I was looking for something which doesn't make me ...

After a month of listening exclusively Melquiades and decided yestoday re-switch everything and to play Lamm’s ML2.
I was quite shocked with the result and I did not anticipate the ML2 could be so way off. I will not elaborate about the a...
|
|
Actually, Romy, I did not think you were kidding, because I get it, just as you gathered. As you know, as I have posted, the ML2 has been the pivot point of my system for over a year now, and this is exactly because of how this facinating&...

Yep, you re right, the Yamamoto A-06S is SET, I did not read it carefully and I was under presumption that A-06S is PP monoblock. Good for Yamamoto! The only amps I heard with AD1 were PP. Somewhere in the very end 90s I shortly was exposed to i...

The Lamm ML3 made me to think about this subject. Since my negative expectations about the ML3’s Class A2 operation turned out to be wrong and since we go into expense and efforts (totally unnecessary in my view as DSET make it worthless) and m...

Greg, I have written about my "DEBZ" speakers several times at this site, including Post ID 3269, early in my original Lamm ML2 thread. I mention these speakers now to compare what we are aiming at here to what I have already done, wh...

Greg, do you have any experience with the Eminence drivers?When the Audax PR380M2 I use (8 Ohm) became unavailable, Dick Osher specified the 15" Eminence driver as a drop-in substitute for the BZ series.I happen to use a single 15 " Au...

It is difficult to generalize but I will. As much as ribbons with each hertz down sound more and more unpleasant the low power SET amps with each hertz down in bass region more and more and more loosing ground. Ok, I am not taking about the real bass...
