I don't agree with above negative comments regarding ML 27.5
I own the unit from new and i love the sound ,look ,feel and build quality of the product.Then again it is to be expected from Madrigal . its pushing 100 w per channel dual mono high current design ,best parts,made for life.
i wouldn't sell mine and as the matter of fact i am looking for a second one in fine condition so i can bi-amp.
i do own tube gear too.i enjoy both worlds.
no ML 27.5 is a keeper for me.sure there are more expensive amps ,but in realistic terms the 27.5 is superfine
it was rated class A in stereophile in its day.
happy listening
