Yes, they are all what I would call mid-fi, but that's not a slam, just their price point. I'd go for the Rotel. It is quite good at its price point, and offers analog bypass for both multichannel input and two-channel. I own an RSP-1066, and I debated upgrading to the 1068, but decided to hold off for a little while longer and upgrade to a higher end unit, like the Krell HTS 7.1 or Theta CasablancaIII.
