The more integrated amps I review, the more I want to tell manufacturers: Please, skip the DAC, omit the phono stage, lose the Bluetooth—just give me the best sound quality, and the most vivid, most transparent line stage and control center (with pre-out) you can design. Make sure this line stage has appropriate gain, and high input and low output impedances. Give me at least four balanced and single-ended inputs. Make sure the volume, balance, and tone controls are durable and degrade the sound as little as possible. That way, I can add a DAC, server, phono stage, or Bluetooth, of any quality level, any time I choose.
