New Lamm M1.2 vs. M1.1

All amps I am aware of take about two months to settle down and stop being a moving target. AC, the signal, takes about thirty days to settle down and the DC portion of the amp takes a minimum of 45-60 days to settle down. At sixty days you will find most amps are a bit too sweet and most folks look in their cable library to find something brighter than what they used at 30 days....I voiced the JC-1s for complete warm-up and complete break-in and to be just slightly warm of neutral when fully cooked. The unit uses some exotic rectifiers, hyperfast/soft recovery types, that just take a while to settle down. I am not aware of other amps that utilize these except those in the aftermarket that modify amplifiers. The JC-1 is a factory hot rod and is the best we can do in a very powerful SS amp built without much in the way of compromises. Just went through break-in here of my personal set of JC-1s and the nastiest part was as I neared 30 days the amps just got thin in the lower mids/upper bass. They spent almost thirty more days sounding like tube amps and woke up at about two months with an attitude......Oh, I am not a dealer any longer for the amps (ran out of preamp customers more than a year ago) and I do not work for Parasound except on a per job basis.....I wanted Bob to know that the thin sound goes away at a month before he gave up and spent a lot more money for other amps.....

Bob Crump: Thanks for your input.

Yes, thank you Bob Crump.

My Lamm M1.1s don't have any problem controling of providing high output with my Wilson Watt Puppy 7's. Remember these are a nominal 4ohm speaker (they don't dip below 3.7ohm) and they are 93-94db efficient. I don't know what kind of power requirements you need, I used an EAD Powermaster 2000 prior with 1000watts into 2 channel's and the LAMM has AMAZING speed and control over the EAD which was awesome in it's own right. The bass is even tighter and images even better.

I still would like to try some ML1.1's on my WP7's.

I listened to WP7's through the LAMM LL2 pre and ML1.1s with Siltech cables using a wide variey of music (excluding Rock and Rap) and never once felt the job wasn't being completed. I never turned the volume controls past 9 o'clock and the music was always fleshed out and dynamic. If you can swing the ML1.1s (now 2.2) do it. If you have a concern about power, get the M2.1/2.2. They are sonically close and over 200 watts but run Class A to around 30 or so watts of power. I own the M2.1s and drive Piega C10 Limiteds with them wonderfully. I was contemplating the WP7s with my LAMM gear because of the awesome experience I had at CSA Audio where I bought my LAMM LL2 preamp. It's going to be the WP7s against the ESP Loudspeakers Concert Grand SI. I can't wait.
