Consonance M100-Plus impressions?

Anyone familar with this piece? How would it compare to the Primaluna integrated amps?

I have a M100-plus and it delivers solid sound and has quality components. Don't expect it to drive tower speakers though. Normal bookshelf is more than enough.

I don't think Primaluna is much different or better after trying it on a Magnepan. Treble is fine but both are lacking in strengh when single amped. M100 has better perf/price ratio.
