No one has any info on these amsp marsh a400 parasound halo a21
I'm using a Parasound HCA 3500, second one. Owned the Marsh in between having the two Parasounds. I'd opt for the Parasound. Also the Marsh isn't as good at driving low impedances as the Parasound. The Marsh was a very good amp though but I like the Parasound better. The Marsh seemed to dry and analytical to me.
