Is your modem router in the same room as your stereo? If so you could do something like hardwire a Sonos connect to your router and then hardwire a hard drive or NAS to your router. Then run a digital cable from the Sonos to your Peachtree. If the router is in a different room though you are stuck using Wifi.
Sonos works fine with Tidal which is not hi-rez but is lossless. It will not do hi-rez recording but that's not an issue for me. However in the scenario above other units can be substituted for the Sonos. I would assume the Bluesound Node could probably function this way, not sure if it can handle hi-rez.
I emailed Blusesound as to whether a USB hard drive canbe connected to a Node2 and they rresponded:
External hard drives/USB Stick
work with the player's USB port. If there's music files in the
external HDD or USB Stick, we'll automatically index the songs and you can play
them directly on your player. Also, they only create a temporary index which
acknowledges the files on your USB drive separate from your library of music of
computer shared folders and NAS devices. As long as the hard drive is in either
FAT32(FAT) or NTFS format, our player will be able to read them.
Thanks for everyone's responses.
