Why is the market for used Levinson amps so slow?

I suspect more people are aware of the 'reputation' for very poor service and high cost for repair/parts. Who wants to put up with that these days?

Only one possible reason - Sellers believe the pieces are worth more than they are worth.

Agree with the above two posts.

Beyond anything ML specific, most who sell on this site have bemoaned to me that the collapse of Audiogon this year has mostly brought the used market machine to a halt.
