re-lar-kvothe,
Absolutely you are correct, you were specifically asking about those two units....and I truly believe both the A20 and X1 are truly amazing products (though I've only heard the X1 and A20 not in my system). And as so often happens, we sometimes throw out ideas that were not requested; sorry if that was the case. I have heard the N200 and the Teminator pairing in a system I know well, and oh my God.....nuff said as Stan Lee would say. Best of luck to you in your choice, let us know how it works out
