[Chr78]

Which one would you recommend for q acoustics concept 20. Marantz pm6005 or the Nad d 3020? I from my computer wireless to my apple tv, from apple tv via optical cable to amp. I prefer a warm, open and detailed sound. Christian

I have the NAD with the Concept 20s - have had them for a few months now and am perfectly happy - they provide TV sound via optical, music from the computer via USB and somtimes Spotify from the ipad using Bluetooth.
