Best Amp for 2000$ or lower. New or Used

Any recommendations.
Mark Levinson No. 23 Cost is about $2K used.

It is a SS 200W/ch. amp.

Very refined, powerful and dynamic.
Has great bass extension.

Works great with my Ayre K-1x preamp in bringing out the most in my music.

My Two cents worth.

PS If it matters to you, was a Stereophile Class "A" amp for many years.
Blue Circle BC24(80wpc)Hybrid. A BC28(120wpc)is even better but tough to find under $2000 used.
