I own the ML2 and owned the L2 line stage. There is something special about the ML2. I know you are looking for more power. I would recommend that you have Vlad go over the amps at some point if you buy them. If you aren't near NY where you can drive them to his place in "deep Brooklyn" it's air freight, which is not only expensive, but probably erratic in these Covid days.
I would try to get as much info as you can about the units, including their history. If the owner is willing to give you the serial nos., you can ask Lamm if they have a service history. If your seller has had them serviced, he should provide you with copies of any paperwork before the transaction.
They are likely packed in wooden crates. At least the ML2s were (and I think the L2 line stage was as well, but can't remember, it's been a while). I doubt I'll ever get rid of the ML2s.
Good luck with your transaction,
