I'd avoid Marsh. They're excellent amps but something is going on with the company and getting info isn't easy. That's my opinion. I like to have gear that a company is readily available if I want them. I may sell my Innersound amp as they are also a problem not answering emails. I had the A400s and it's an excellent amp if a little on the clinical side if anything.
The AES three will put out dc which bothers me. It's also very syrupy sounding. Consider a used PV 10 or an older Audio Research tube pre.
