How a pair of Mark Levinson ML2 stands with the best amps today ?

Yes, they do! Designed by Tom Colangelo. 30 mono watts in the later versions @ 8 ohms and doubling to 60/4 ohms and 120/2 ohms! Ideal for the Quad 57's. Sold new for $3600 pair in 1977. A true and worthy classic design!

More designers should look at these, legendary amps, and mimic them.
They could drive anything, to given level, with out becoming a tone control.

Here is a 3 angle pic of a pair of these magnificent Mark Levinson ML2’s 25w into 8ohm monoblock beasts.
Yes you read right only 25w, but it’s pure Class-A, and the amp supposedly can double all the way to 1ohm or very close to it, 50w into 4ohm 100w into 2ohm and 200w into 1ohm.
