Arthursmuck,
Owning the Lamm M2.1s, and having heard, and coveted the M2.2s, I can tell you that while the M2.1s are top contenders, the M2.2s are the champ. (So if for some reason you were to change amps, the M2.2s would be the ones you would want, as they are the equal to the VAC 300, whereas the M2.1 is merely a close second.) The M2.2s are just a bit more transparent, and have a significantly better treble response. (The M2.1s have just a smidge of darkness to them, whereas the M2.2s have a wonderfully extended and airy treble response, only beaten by the aforementioned VAC 300, and even then, the VAC is only very slightly better.)
The darkness of the M2.1s can be mitigated through the use of NOS tubes, and really good speaker cables. (I too use the Amperex PQ Pinched Waist 6922s, and the Nordost Valhalla speaker cables are a perfect match for the M2.1s.) The darkness that is left is merely a hint of darkness, and most people listening to my system don't even notice it. It is only because I am so used to the M2.2s in my friend's system, that I even notice it myself.
With that being said, when a used pair of Lamm M2.2s show up here on Audiogon, I hope to be in a position to buy them. (However, they rarely, if ever, show up here.) The M1.2s seem to be much less of a rarity on th eused market, and I might give them a shot, even though I think they might just be just a bit underpowered for my system, as I use the EgglestonWorks Andra II speakers which are pretty power hungry. (Although, I know that Paul Bolin uses them with his Andra IIs, which is why I might consider them.)
