A Salk Streamer will replace the Mac Mini as the processor, but the mini will remain to load Hi Rez from sources to the shared External HD. Using a Linux based App will be completely new to me. The first issue is what brand SSD provides the best value for storage at this point? Second will be solving the new Streamer install. Jim Salk seems to be very accessible and personable so I look forward to the test. DEMO ROOM OFFER to any in the West Michigan area - my demo room is open to hear this new Streamer with the AURALiC Vega DAC, Calyx FEMTO DAC, EggWorks Speakers and McIntosh Power. What a great time to experience Hi-Rez! Thanks for your recommendations on the external drive or with any assistance using the Salk Streamer.
