The Lamm hybred are nice on the 1s but the ML1 (90w) are much better all around. You can't believe the base you get from the ML1 though the hybred does a little better in this regard. I had the M1.1 hybred at home with my 2s and this was definately the best I heard the 2s but the 1s preferred the ML1.
These guys have me all hyped up about the Tenors. I have always planned to eventually own the Lamm, and this may still be the case, but when the time comes I will be definately checking out the Tenors since they are using the same 6C33C tube but I will have to be wowed to change the impression Lamm has made on me. As a interim I am considering the Joule Stargate...seem to have the same signature I am assuming from the 6C33C again.
Sorry, I have ignored the the MA1 is 1/2 the money as the Lamms and Tenor so if 10k is your retail limit you probably will be hard pressed to find something better. Bottom line is you can't go wrong any of the ways mentioned in this thread and you will love the 1s...Kharma has not gotten its due in my opinion and Stereophile really did a disservice to the 2s when they reviewed them.
With the music you listen to, you will be extrememly happy.
good luck and good listening,
cd
