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

I think the ML2’s over the Classe by quite a margin.
The Classe uses Darlington output transistors combined driver/output, not great can’t be controlled as well, never really caught on in hiend audio.

And the ML’s use separate driver and Bi-Polar output much better scope for tuning for stability etc.

Those Levinson amps will drive a 2 ohm load for 30 years.

 Power supply, capacitance is off the chart, even by today’s standards.

  Have them serviced by a competent tech, or the factory techs.

 AMAZING AMPLIFIERS, you will love them.

Here’s lots of info on them https://www.marklev.com/2013/04/
The WTconcept resto site was a great to see one with dozens of HD pics gets a complete resto job done,  http://www.wtconcept.com/levinsonml2/  but it closed down, even "WayBack Machine" hasn’t got it in it’s entirety

One of the Ten Most Significant Amplifiers of All Time:

Mark Levinson ML2
"This John Curl designed amplifier established Mark Levinson, the man, as a driving force in the audiophile marketplace. The 25-watt ML2 monoblock, Levinson’s first power amp, was designed for wide-swing-impedance speakers such as the legendary HQD system (Hartley, stacked Quads, Decca Ribbon)."
