@M-DB
I will make the assumption (not a good thing to do:() that you use iTunes for your music file playback and mysqueezebox.com for streaming from the internet ? The Metrum dac > 75Ω coaxial input is limited to a maximum data sample rate of > 176.4kHz, the Toshiba optical link limits at 96kHz so there is not much benefit to be gained from installing the EDO applet on the SBTouch. Likewise your Mac-mini is restricted to High Sierra, and frankly, installing LogitechMediaServer on the Mac-mini is too much of a hassle. My suggestion is that you purchase a raspberry pi 3b+ or 4b (2g) with the official rpi foundation power supply and a good quality (see Sandisk) micro sd card. If you buy new, then do so from a seller approved by the Raspberry Pi Foundation. There are daughter boards for the raspberrypi called HATS. Some of these have SPDIF (co-ax and Toslink) outputs. Raspberry pi and HATS are sometimes available second-hand from furum members upgrading. Install LMS on the raspberry pi using the piCorePlayer OS and also utilise the raspberry pi as the player (with attached HAT) and plug the preferred output into the Metrum dac. Connect the rasperry pi to the network via Ethernet Use the SBTouch to control the player output from the raspberry pi (with your Mac-mini running) you will be able to access the iTunes music files. This will not provide any great change in sound quality but will enhance your user experience and prove a relatively low cost introduction to "digital options" There is a learning curve :):), but plenty of support is availble from the members here Please let us know your approximate location, there may be someone close who can offer a trial unit or invite you to a demo. Don't rush; have a think about how you want to proceed and do some research :p. atb ronnie ------------------------------------------------------------------------ Man in a van's Profile: http://forums.slimdevices.com/member.php?userid=43627 View this thread: http://forums.slimdevices.com/showthread.php?t=114783 _______________________________________________ Touch mailing list Touch@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/touch
