Some folks asked about tube alternatives for the M1.2. Check the sidebar: Power, isolation and tube rolling.

A brief update to add to the list of tubes rolled...

Finally had a chance to try a nice pair of Siemens Halske 6922 gray shield 1965 (A0 Series) in the Lamm M1.2 Ref. Very nice definition around performers and instruments that yields excellent dimensional presence. Bass is as good (maybe a teeny wee bit better) as the top-rated Amperex 7308 '63 PQ shield. Maybe not quite the tippy top extension of that tube but close with high resolution without hardness. Ever so slightly cooler but rich harmonics that contrast as ever so slightly lighter than the lush, dense Amperex string tone. Leading edge transients are crisp with definition though maybe not as pizzicato-snap-sharp as the PQ shield though decay will last and last until the end. A wonderful tube, it wedges its way into my top 3.

I used to have the Lamm 1.2 till last year. I did some tube rolling in it as well and ended up with the Amperex bugle boy which was best in my modest opinion.
My lamm liked a tube that reinforces a bit the lower end.

I have yet to get into tube rolling. I'm SO in love with what the system is doing now, I'm almost afraid to fool with it. Who knows, maybe I'll make an attempt at tube rolling in the future. What did you replace the M1.2s with? What preamp did you use with the Lamms?

I suspect that is true for any tube amp. The Bugle Boy opens the door to the Amperex sound and that suits the 1.2 and 2.2 quite well.

Its hard to question satisfaction - you're in a good place! Most of us who've been at this for a while get the intellectual notion of improved sound, but it's only truly known with experience. We're lucky, the M1.2/M2.2 only have One tube each! If you haven't rolled tubes at all, much less with the M1.2, I am confident you would hear genuine improvement with the right tubes. The tube in these amps has a meaningful impact on their sound - that's why Vladimir chose to include a tube and place it where he did in the circuit.

tima...great review Do you have any sense how the M1.1s sound relative the M1.2s. I occasionally see M1.1s come up on Agon for $6-8K and if it gets in the ballpark to the M1.2 sound that might be an affordable way to go. I am assuming the M1.1 would be an upgrade from my Ref 110 in the areas of bass depth and articulation, tonal density, dynamic range, and overall frequency extension. Paired with a Reference ARC preamp that should be a good combo. Occasionally I see M1.2s come on used market in the $11-14K range and that would be the preferred path to go but 2X the M1.1. So just wandering if you have a sense for M1.1 relative to the M1.2. Thanks.
