Ron’s New System

[Lagonda]

A little light reading for you , Of course *some* will say that is just Romy being Romy , well I tend to look past the somewhat eccentric delivery and focus on the message that he is conveying .

I guess the idiot mentioned by Romy is our own Steve. He is a annoying character that Romy fellow, talk about idiot !

Which line stage preamplifier do you think is the most tonally "dense" and full-bodied?

I thought you weren't into audiophile attributes.

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 done somehow by phase’s manipulation but what exactly it was I do not know up to the few days ago.

A few week ago learning how the pro audio spatial expanders work and familiarizing myself with third sound I detect that in the very-very minor and very precise depth of this affect the sound coming after the spatial expander very much reminds me what Lamm’s SS preamps did to sound. Even some problems that spatial expanders had were very typical for the L1/L2 preamps.

Briefly: a spatial expander is a mechanism of artificially creates spacious more sound. A spatial expander does not generate more realistic sound, but more pleasant sound. The spatial effects are accomplished by mixing into each channel an inverted crossfeed signal from the opposite channel to vary the presence of the mono signal. The effect widens the soundstage, create a separation between the instruments, “inverts” tones by injecting into them a small particulates of own out-of-phaseiness and has some other subjectively pleasing effects. The tradeoff is reduced focus and loss of bass, because bass signals tend to be monaural.

So, if you add to the spatial expander’s characteristics the L1-L2 this dally degrading transients capacity and dally incising dynamic compression due to the faulty designed powers supply (unless you are wiling to change the tubes in there weekly and I suggest above) then you have a have very clear depicture of the L1/L2. A couple days ago when I was contemplation it I had a conversation withy a guy that I know to whom I shared my views about the spatial expander and Lamm SS preamps. After listing me he said proposed that in such case the L1/L2 should perform better and be more transparent in bass region if it switched in mono. He, owning the L1 and L2 did report that it was his observation in past that mono music sounds better on Lamm’s preamp. It was very promising. Today the same guy went to a listening room of another person who has cruelly L1 with mono switch bult-in and they made an experiment playing music and flipping the mono switch. The reported that bass become much better in mono setting… the way how it should be in case the spatial expander was used.

Well, it looks like the secret of the X-factor is resolved. Unquestionably it was very good Lamm’s intention with L1 and L2 but unfortunately it was not implemented at the level of the serious listeners might demand. I wonder if would be possible to replicate that X factor (sponsored by the spatial expander effect) only at the more demanding level?

Ron mentioned “the four box Lamm preamp”. It is clear from these snippets that Romy had not heard the LL1. He does speculate a lot. I own the L1 and the LL1. They are both excellent. The latter with separate mono boxes achieves greater instrument separation, sense of space, and a more natural bass presentation.

Wow, what a nut, with an obvious Lamm axe to grind ! Someone should put Raul, Carlos and Romy the nut In a room together and make a conspiracy reality show out of it !

For many people the lack of a remote control is a dealbreaker. It is not a dealbreaker for me.

For me it is a bit problematic that the Lamm LL1.1 Signature is a single-ended only design, and the Io sounds best using its balanced output. (The LL1.1 Signature has an XLR output connector, but it is "balanced" with only a transformer, and not with a true differential circuit.)

I think the output impedance specification of 16,500 ohms is a typo.

The Jadis, also, is single-ended only, with no remote control.

1- Remote Control is not good for sound quality
2- the Output impedance of TAD C600 pre is also high at 3.5khz but there is no problem when use it with TAD power amplifier. You can use Lamm pre with Lamm power without any problem
You refered to input impedance or output impedance?
3- The single ended design is better for musicality

I have read these three ideas from good designers

 

[Amir]

psuedo balanced XLR out
pin 1 = signal ground
pin 2 = signal output
pin 3 = not connected.



The manual says the input impedance is 16.5 KOhms. Why do you think it is a typo?

Pin 3 is not connected because of avoiding ground loop?

On the contrary ! , from his writings Romy appears to like ‘Some’ Lamm electronics .

He is still a fruit loop !
