I'm connecting my Sonos Connect to a Yamaha RX A-730 Home Theater receiver via either TosLink optical or Coax digital cable. Either one works fairly well, but I have to have the volume on my Yamaha turned almost to MAX. So I'm thinking I need some sort of pre-amp.
Can anyone recommend a digital to digital (either toslink or coax) preamp to install between my Sonos Connect and my receiver ??
