Hello, I am helping a friend build out his system. He has an EMM Labs Pre2 Stereo Pre-Amp. Friend plays ( Blu-ray Audio, LPs, SACDs ). He says that the rest of the system is at least as high fidelity as the Pre2. Friend wants me to add a computer, of at least as high fidelity as the Pre2, so that he could download and/or stream internet music. Would a Mac mini suffice? I presume it would need approximately ( external HD = thunderbolt, internal HD = 256 Gb solid state, RAM >= 8 Gb ) ? Which (if any) of the C.A.P.S. v3 machines would be appropriate? Would friend need a computer better than a C.A.P.S. v3 Zuma? If so, I could build it, but where is the bottleneck in the Zuma? Are there any pitfalls I should avoid in selecting eSATA or NAS for the C.A.P.S. v3? Apparently he would copy from HRx to hard drive on a different computer, then transfer to C.A.P.S. v3 for audio playback. To me it seems more natural to connect both computers to the NAS. Thank you.
