I too love the Lamm amplifier's sound.
(I use the 200 wpc M2.1 hybrid monoblock amps.)
A couple of my friends use the successor to my M2.1, the 220 wpc M2.2
monoblock amps.
(They sound slightly more transparent and have a more extended treble
response. IMHO the bass is almost the same, just slightly faster.)
If you can afford them, the 110 wpc M1.2 reference monoblocks are what
you should buy, IMHO.
One thing you should do, even for your M1.1s, is replace the stock
Sovtek tubes with some NOS tubes. (Using NOS tubes helps to close the
gap between the older units and the newer units.) A big step up is to
something like the Amperex Orange Globe 6dj8 tubes, which are relatively
inexpensive,. (I use the Amperex pinched waist 6922 tubes, but they are
really expensive.)
My two cents worth anyway.
