[quote user="jessie.dazzle"] I have not heard any other systems using Vitavox S2 drivers, but I know it is possible to get the S2 to generate on-axis unpleasentries. In the case of the system I am building, one can happily sit straight in the firing ...

One of the greatest and the most important things for me in power amplifiers is their ability to differentiate tones. When you listen live music you practically never hear two identical tones. Even two identical pitches presented after the diff...

It is completely irrelevant how frequently an amp switched off and on if a soft start is made properly. A few years ago my friend and I, having the 6C33C based Lamms ML2 (where I do not like how the soft was working) , noted that we both change the o...

I was thinking about the subject for a long time. People in audio love to make generalization, so do I, but in it is not so simple. People attribute to output tubes some “special” qualities but I more interested not about unnecessary drooling about A...

Pall, stop to talk about VTA when you are talking about amplifiers and stop talk about VTA when you are talking about electricity. Sorry, it sounds juts insane. VTA is a subject of interaction between a records and cartridge; it is not the subjec...

Well, it is not necessary a fully qualified urban legend as the problem does take please with fixed based 6C33C but..... only under certain conditions. I have written about it a lot on my site but will very briefly recall it again.

[quote user="Tommy"]I believe that congratulations are in order for the great threads on Audiogon sewer; the Lamm LP2 and WE417A tubes and Wavac 805 vs Lamm ML2.1. [/quote]Yes, it was almost fun.
Unfortunately most of these people are quite primiti...

Jessie, since I got my amps I have followed Romy's suggestion and recycled swapped-out V2s into V1 service. As it happens, I do not run V2s (or V1s) over a year, but I have had no problems of any kind that I can relate to following the annual V2-to-V...

[quote user="Romy the Cat"]Because GM70 can work in A2 class the ML3 has a very powerful high current-capable second stage (I do not know it they are 4 parallel 6H30 of some kind of composite follower) to be able to handle the GM70’s grid current.[/q...

It is interesting: I am running now Zarathustra amp with my woofer towers, line-level crossed at 90Hz with fist order. Everything is very fine bass-wise, with very minute touch of dominating smoothness. To my surprise the typical upper-bass har...

[quote user="KOTriode"] On dynamic, the 6C33C tube showed its ability to go deep in the bass on Ray Brown trio recording of Soular Energy which is excellent for a 15W SE , the 845 amp can do better, but not by much, but probably because of its 25W ou...

Paul-Again the disclaimer - I don't have a schematic nor is the circuit board fully visible, so these are solely my speculations and I could be wrong. 'What is the
MKP's value, and why do you think it's "the" coupler, while the 'Cubes
are else?'I...

[quote user="jessie.dazzle"]As for balancing the amplitude between channels by driving them from different taps: I drive the upper bass horns form the 16 Ohm taps, and everything else from the 8 Ohm taps. An 8 Ohm versoin of the upper-bass driver...

[quote user="Antonio J."] … looking like the Kemp's unit. But that's provided the input electricity is still under 5% of distortion. They also state that that performance is under linear load, so it might be possible that using chokes or trannies loa...

[quote user="drdna"] Option #2 is appealing since it will free up a lot of space and make the equipment more cat-proof. I was thrilled to come home a month ago to find the tonearm wires chewed through and the tonearm swinging freely. [/qu...

[quote user="Paul S"]Now I am wondering: If we go to such trouble to have transformers wound for our particular applications, maybe we could just as well be winding our narrow band voice coils and welding them to our/their own output tubes.[/qu...

Quotes from Romy in blue: "...Anyhow, I do not know at which stage your project is what I think you are somewhere in a process of integrating the drivers..."I would like to stabilize the system, and listen to the existing horns, while ...

[quote user="jessie.dazzle"] If you've tried both, and decided to keep the 16R versions, you've answered a question I've had for quite a while; I too use the 16R version, but have always wanted to try a pair of 8Ms with 8 Ohm coils (should have o...

[quote user="jessie.dazzle"]Upper Bass : Frequency range between 100 and 500Hz – Driver loaded into a 120Hz straight horn, driven by DSET dedicated channel. Mid Bass : Frequency range between 40 and 100Hz – Driver loaded into a 45Hz straight hor...

Frankly speaking I kind of thankfully drifting away from observing what is going on in the industry and particularly in amplifiers. Since 1998-99 I was using explicitly Lamm amplifiers that were heads and shoulder more interesting then anything else ...

Well, it is always difficult to me to deal with audio people because any expressing any abstract notion in front of them those enslaved people perceived as a preamble to some kind of “deliverable good” and the sick audiophile imagination has already ...

Well, as a prototype it might work but as the Milq sound
that I was implied the amp with no gas tubes in bias supply is not good in my
view. I never was satisfied the way how a regular 6E5P driver 6C33C. To me it
was very perfunctory and much unso...

The reader who read my comments above about Lamm’s new ML3 amplifiers might have wrong impression where I’m coming from. I have a general tendency to be skeptical (because the experiences) when I exposed to audio but in case of ML3 there is much deep...

Yes yes yes .... Lamm Industries is a BUSINESS... This is abundantly clear whenever I order tubes from them!
But the most desirable of Lamm's past creations are not the kind of things born solely of a desire to make money.
I understand Lamm's ...

[quote user="HookEm"]The reproduction does not seem natural... too far away from what I would hear at a live event (e.g., female vocalist). Sort of bright and fatiguing at times. I may not be using the proper terminology to describe it, but I do...

Hi Romy,
I just want to add my experience I had last year with a transformer based (actually it was an autoformer based) "passive" preamp. I thought that this could be the final solution in my preamp quest. Alas, it was not the case.&nbs...

Very sad to hear it. My condolences to his finally. I hope Vladimir eventually got peace in the end of his life. I did not talk to him for over 1o years and I do not know what he was all about last years. The last contact I had with him it was I ...

[quote user="morricab"] You are also right that to get everything you want from an output transformer requires a VERY expensive construction and top materials. However; even an expensive transformer is no guarantee of success. [/quote]
Sorry t...

Thanks, floobydust.
There are a lot of interesting points in you post to consider. What speaker you drive with your 2A3? If they are relatively high sensitively (like compression drivers) then did you consider going with a single stage? I think I ha...
