Anyone compare the push pull tubes to the hybrid SS amps that Lamm still currently produces?

I have considered the ML2.1s many times, but still a bit concerned about SET bass in my room- several 845 SET amps have not been up to the challenge, but I realize a 6c33 tube is considerably different despite being a triode.

I have both. I would go with the M1.2 in a heartbeat particularly if you are worried about bass. Bass was not the ML1.1s strong point. Oddly enough it is its upper registers. In fact, despite the power disadvantage of the ML2.1, I felt the latter had more punch and pitch definition down below when driving DB-99 SEs (99dB sensitive at 1w/1m).

I haven't gotten my hands on any ML2.2s yet. The SET market is tiny in the already small market we have.

Did you ever get to try the A3.5r Mk2s with your Zus Keith?

I have had them about a month, although I let a friend borrow them for the past two weeks---anxiously looking forward to their return. They are super smooth, but vibrant with a nice organic midrange. Will be interesting how I deem their resolution vs pure tubes next week. Bass is very good for Class A.

How outclassed are they by the Lamm M1.2s?

Hi Arthur,

The one to ask is Mullard88. He's the one who turned me on to Lamm. He had M1.1s then went to M1.2s. I only listened to his M1.1s briefly but liked it well enough (understatement :D ) to take on the line. We did pop the hoods to retrieve his tubes a few years later when I delivered M1.2s. The layout and many parts were clearly different.

With high sensitivity speakers they aren't outclassed at all. A client is using Valvets with his Avantgarde Trios with custom Basshorns (compact version). Another, yet one more dyed in the wool tube guy, is using them with his Living Voice OBX. They have one advantage over the M1.2s. The M1.2s take a good 2 hours to start sounding their best when ambient temperature is low. Ironically that is the case with me because I'm always using AC in this tropical country. The A3.5s take something like 30 minutes. Regardless of sensitivity however M1.2 bass is tighter and punchier but it isn't as smooth up top. A3.5 Mk2 mids are likewise a tad smoother but the tradeoff is density.
