One of the nicest features of ARC Reference Phono 2 (SE) is it's features
and neutral sound, both of which means good compatibility with wide range of cartridges.
Cartridge choice can be based optimizing cartridge with deck/arm-combo, not limited by RIAA itself. I'm very pleased with current set up of Oracle Delphi mkIV, SME V and Benz Micro Ruby 3 MR connected with Nordost Valhalla.
