It's pretty much a matter of which phono preamp and which receiver. The Outlaw R2160 apparently has a very good phono stage. The entry-level Onkyo 8020 apparently has a not so good one. Marantz integrated amps get good mentions. Many vintage receivers are known to have nice phono stages, as that was a big deal then. It's definitely a good thing to be able to return a separate phono preamp if it isn't the improvement you hope for.
