I own the Boulder 866 and it is a outstanding American build product. Have not heard the M8 but there reviews are quite good. I can attest that Boulder is a great company and everything is made in house. Have you had a chance to listen to both amps?
Boulder 866 / Rotel Michi M8
Michi M8 big boys against the little sophisticated Boulder 866 all-in-one?
Advantages disadvantages?
I had the opportunity to bring new michi M8 monos with a warranty of $5000, but there are also quite a few good reviews about the Boulder 866...
They play in the same league?
Thanks!
