I have a dedicated (older) MacBook Pro i7 -16GB Ram -(512 GB-SSD for system and Software, 2TB HD for Music (internal-I replaced the DVD/CD player drive with an OWC HD. My output is Amarra (Sonicstream) (Amarra EQ is turned off)and I think it sounds great.
Am I getting the best out of Roon? I could also go system out direct - Toslink out to Toslink preamp in (older MBP had Headphone/Toslink out. Not the newer ones (headphone only)
I use a newer laptop for Audio out. Older Mac for Roon Core. Both computers are connected to the Ethernet on the same Ethernet switch (unmanaged)
I do not have CoreAudio as an output option on my Computer Sound Output options ?
