For the last two months, I have enjoyed the NAD D1050 DAC from the new D range as my headphone amp at work, and it's been absolutely great

both the DAC and the amplification stage truly are a fantastic deal at $1k! and to pack high quality, honest 50W -most amplifier vendors in this price range lie- into such a small package is no mean feat

Since the DAC was great, I took the plunge and replaced my AV 7.1 receiver with a D7050.I had already dropped the surround

For less than adding a sonos to your old amp, you could have a great new amp, with solid DAC, plus airplay, spotifty, bluetooth, USB, and ethernet options to play your music
