SET amp owners thread

Romy has some very interesting ideas about audio. I

Perhaps he is more effective at communicating those ideas in person though I don't get that from his videos. Best I know is his 'appeal' comes from his lack of language skills and a quirky way with English. I don't find him authoritative on anything, but then I don't understand most of what he says.

Perhaps that Is because you have very little technical or real world practical hands on knowledge of the transducer equipment of which Romy speaks !

I had thought you heard the ML2. My mistake.
Romy writes many interesting things on his site. And his opinions are strong. Note this comment about the ML2 compared to its successors and ML3.


“I do not have any disappointment that there was no serious public overview of ML2. I have quite low esteem to audio public generally and to the people who facilitate public overview in particularly. It has nothing to do with cynicism but rather with objective observation of the reality out there. It is kind if shame as it never happened as the ML2 is gone and the current production of ML2.1 has nothing to so with ML2 legacy. In addition Lamm, as I understand nowadays abandoned any ideas of good sound and goes to cash out the market of mid 90dB-sensitive speakers buy buttering up his prospective customer on the idea of ML3. It will be basically the "new ML2 type Sound" approach only with the unnecessary 40W, based upon high-voltage-compromised, more powerful output tube.

Regard the rest. You might discover eventually that despite of beneficial contribution of some exotically performing audio-elements and despised that some of them are able to inflict long term listening consequences to listening culture but the only thing that counts is not the capacity of the audio installation but the way in which that capacity is used but the system owner. From this perspective all those audio toys are quite irrelevant…

I’m glad that you are in your way to discover the vintage ML2 – it well worth it. Spend a couple years with those amps – you will observe and learn quite a few interesting things. In 2001 I have written somewhere at AA that ML2 is able to demonstrate it’s sonic advantage even when it is not powered on. I remember that all Morons out there informed me that I was an idiot. They are fortunate that they did not know how it really felt about their competence on the subject or about their primitive understanding what the subject really was.

A pity you choose to quote and defend Romy considering his infamous (not just strong) writings about Vladimir Lamm in his site. I am no longer a Lamm owner, but respect the man and the company, I am out of such dialogue.

BTW, it would be nice if you have your own opinions on the subject, not just parroted words.

Tim,

Did you ever read what he wrote in his forum about the Lamm products, Lamm reviews and your colleagues in Audiobeat?

I have a very long system thread in which I share my thoughts about the gear and how the system sounds. Look it up. You can read all about my opinions there.

You have zero experience with the ML2. I do not think you have ever heard my speakers. So you know nothing of the combination.

I am not defending anyone. He simply seems to agree with others who have told me that the original sounds better. This seems at odds with your opinion but then you have not heard the original so should have no opinion.

Tim,

Yes, I have seen many of his Web site writings on Lamm. I have heard some of his videos. His language skills (Romulan ?) perhaps done on purpose shows him as an ineffective communicator. He might be better off if he wrote in his native language and has that translated by someone else. I do not regard him as having any particular insight or authority on Lamm -- easy to be a critic, but his opinion is only that. He liked the original ML2 over the ML2.1 as does David. Okay.

I recall he made some snarky comments of little substance about the publisher at TAB. He's made snarky comments about others as well.

His Web site yields a time out.

 

[microstrip]

(...) You have zero experience with the ML2. I do not think you have ever heard my speakers. So you know nothing of the combination. (...)

Surely you can tell me that your system sounds great and I accept it, as well as many other of your subjective findings. Pretending I do not know anything about the gear just because I have not listened to it is ridiculous.

I am not defending anyone. He simply seems to agree with others who have told me that the original sounds better. This seems at odds with your opinion but then you have not heard the original so should have no opinion.

I was addressing you direct questions based on the designer/manufacturer opinion, many reviewers and signed comments. You choose to ignore them and refer your two usual references on the subject (Romy and DDK). Ok.

 

[microstrip]

(...) His Web site yields a time out.

Yes, but you can't imagine how destructive his comments can be to Lamm reputation, thanks to google and now AI. Several audiophiles in Europe that have shown interest in my ML3 - LL1 system gave up after finding and considering them. They are hard to reject by people who do not have technical skills.

These audiophiles gave up after reading comments by Roman? Maybe this is a blessing in disguise. The ML3 is not a set-and-forget component.

Perhaps you have saved yourself future aggravation by not selling to someone who is dopey enough to listen to Roman?

A blessing? No, it was not for me. After loosing several interest people, I had to sell them very cheap, loosing a lot of money.

Some of the people who got them are members of this forum. Properly operated Lamm is reliable and easy to use - I explained all its peculiar characteristics to prospective buyers. In fact, the main issue is the mains stability - a 3% increase in mains voltage is enough to destabilize the amplifiers and burn fuses or tubes. BTW, it is not an unique case.

I am sorry to learn this.

A drop from 120VAC to 116VAC -- not unheard of in the USA -- can de-stabilize the amplifier and burn fuses or tubes?

Did you experience this yourself when you owned the ML3s?

 

[crosswind]

^ That sounds a bit peculiar. Here in Norway the mains can have a 10% variation, meaning the nominal 230VAC can be anywhere from 207 to 253 VAC and still be within regulated limits. I guess Norway wouldn’t be a good place to own Lamm gear then.

Drops are inoffensive - the problem is when mains increase, causing a significant increase in current and power in tubes - Lamm drives them hard.

After I started operating them with an adjustable 3 KW auto transformer I did not have any more issues,

Lamm also quotes a 10% mains operation variation. The problem only happened when after adjusting the bias there was a rise in the mains voltage.
The question is mains stability, not the nominal value.

Anode voltage range is 1078-1102 volt dc if it is above it would reduce the bias.
Max Plate 125 Watt at 1100vdc × 0.11 ampere you run 121 watt.

P.S i would no go over 90mA ( 0.9volt testpoint) want to use the tubes longer and have fun

Lamm drives them hard.

Always a mistake … One has to wonder about distortion measurements under load for Lamm amplifiers ?

As far as I remember bias should be set at 110mA in the ML3 - and it was critical for sound quality. The GM70 had to be regularly replaced.

If a tube runs cooler, you increase the distortion. I think you'll have a hard time listening if the amp at full power produces 3.8% THD instead of 3% THD. But I would use tubes for 5-6 years and be happy, regardless of the mains voltage.

At 10%, you'll encounter completely different problems that many people don't consider: the tube's filament voltage. This can drastically reduce the tube's lifetime.
If you heat the tube permanently with 7 volts instead of 6.3 volts, that's not good.

Amplifon gets over 30 watts with <1% THD and about 42 watts at 3% with the GM70. However, I think they are driving it even harder than Lamm because they are squeezing another 10 watts from it.
