I don’t know it will be exactly the same, but I’d take Anthem over a lot of mass market designs.
If you are looking at 2 channel integrateds I’d strongly suggest hte Parasound as a close match, as well as Ayre on the higher price side.
I can't speak to every brand out there, but in the past I had a Theta casanova and thought I could substitute an Onkyo or Emotiva with the (then) new HDMI connectors. I was very wrong. They sucked at the time. Point is, you really should listen cause the Arcam is a very sweet sounding piece of kit and you are not going to be happy with a generic AVR.
