Preamplifiers: keys to mystery – or…. how a preamp might be not only a load-driving gadget.
Years after years the preamplifiers are being a “terra incognito” of audio people. I admit that preamps are a subject of my persistent curiosity. I was alway...

Hi Romy, I've read several of your posts on audio asylum where you indicate the L2 is far to superior to the L1. More recently on this site you wrote, "the X-factor of L1 (the ancestor of L2, that BTW was way better preamp from many perspec...

[quote user="steverino"]I think my statement " Because we can't map it precisely from the stage to the speakers..??" was on the right track. Yes there is a distortion of spatial information from performance to speaker in the same manner that a ...

Hi Romy,
Thanks for your comprehensive reply. Based on your description, the L1 might be a good match for my system and taste. I tried the L2 and didn’t think it was nearly as veiled as you describe, clearly everything is relative. I also expected t...

It six month as Lamm released his LL1 preamp but I do not see any “jitter” about the sound of the unit. Even the Lamms’ leash-driven, in-house bitches from Soundstage do not publish any “review”. I did not see even any talk online about LL1. This is ...

Ethan,
Since I published the article “Preamplifiers: keys to mystery” I received many emails from my site visitors asking about Lamm prams and questioning my remarks in comparing what I said to “data form other sources”. Some people disagreed or sur...

I probably never get tired to mention the stupidity of the folks
who write for Audio publications. This time my hero is Marshall Nack of positive-feedback.
The hero just published a review about the Lamm updated preamp L2:

[quote user="guy sergeant"] In your earlier piece about how to use the S2 'properly' you wrote
"Whatever happens between the 400 and 2,5 is pretty much unnecessary for you garbage. So, get any known to you soft capacitor of 3uF and place it in serie...

Paul, there is a number of inaccuracies in your post.

[quote user="jessie.dazzle"] For now, the amplifiers I use are a pair of Lamm M1.1s (was going to look for a pair of used ML2s, but more and more considering building a pair of Meliquaides). Using the M1.1s with a pair of V.A. Parsifal/Encore (direct...

Positive Feedback published David Robinson’s review of Lamm M1.2 amplifier.

Yes, it is a bit ridicules to have 4 boxes – a clearly money-raising project. Probably Lamm need to make it 2 chassis init with box #5 is to store manuals and box #6 to store the tube replacements. Talking about tube – one gain state with 4 paral...

Who read the article above about the Lamm L1 and Lamm L2 preamps knows how high I prize the effect of spacious reengineering that Lamm preamps do. I call it the X-factor and was not familiar what it was and hot it was accomplished. Obviously it was d...

[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...

Perhaps you are right. Buying out tubes from manufacture is a secure way to go. Still, I abandoned this practice in 2002 when Lamm sold me a pair of 12AX3 for his L2. When I got them one of the tubes was with paces of metal riddling inside. I figure ...

Jessie, this is a whole idea: do not get a signal into the ML2. It is NOT an operations sate but juts immediate testing. Do NOT short the ML2 input when preamp is connected to ML2 XLR inputs. By shorting the amp’s inputs you hear the inner-noise of t...

It is even hard to critique because it is beyond of being ignorant of stupid. The John E. Johnson’s review of Lamm L2 preamp in the “Secrets of Home Theater and High Fidelity”. Below are the fragments of the John E. Johnson’s pearls… Each quoted stat...

[quote user="Paul S"] I think that bit of marketing hype must derive from Lamm's ML2 (& 2.1?) "Operating Manual", which says: [the ML2] "Maximum Output Voltage" "with continuous sine waves, at 1kHz @ rated line voltage" [is] "(blah, blah, blah), ...

People, keep asking me about the sound of Melquíades and I feel strange as I really can’t not explain how it sounds. It does not make any sense as I initiated this thread with the objective to explain or at least to inform about the Melquíades’ sound...

Ok, let dive a little bit further into my examination of the subject of Lamm ML3
What is important is to undusted that my view less targets the Lamm ML3 but rather it targets the ML3 as a representative of entire class of amplifiers. When I to...

I do not think that to be reasonable is a tall order, in fact I would insist that I nothing but reasonable.
Still, I feel that it is a huge distraction for people and a disappointment for me that others see juts an amplifier with a bi...
