Hi - I am new to Roon and initially very impressed - but I have invested in a large High Res music database - stored in Flac on my Synology DS213j NAS drive. I have an Onkyo TX 8270 receiver (chrome cast built in) connected by Ethernet to my Network ( Netgear Modem and TP Link router, and BT Whole Home Wifi Mesh)).Roon Core is on my Apple iMac 27 MNE92B/A All-In-One Desktop, Intel Core i5, 8GB RAM, 1TB Fusion, Radeon Pro 570, From an audio perspective everything works great 192 at 24 bit streams effortlessly , but the Onkyo app is very clunky for playlists etc.
I also have four Onkyo wireless NCP 302 speakers( chrome cast built in) , two old Bose speakers connected via chrome cast 2nd generation and a Samsung HW -K850 sound bar connected via chrome cast 2nd gen.
Roon recognises all these speakers and synchronises well but seems to reduce sample rate down for the Onkyo receiver - typically will reduce from 192 - 90 when linked to other speakers , but when connect on its own will reduce to 44.
Obviously as music quality is the first priority can’t see me keeping Roon beyond the trial stage if I can’t get it to send the full 192 file to my Onkyo receiver
