The Parasound Halo A23 is a stereo power amp, not a stereo integrated amp. If you get the A23, you will still end up using your Yamaha receiver as a preamp and DAC. You will need a good quality stereo integrated amp such as the Hegel H160, Musical Fidelity M5si, M6si, Rotel RA-1592, Parasound Halo Integrated, etc.
