Instead of :
Music --> PC --> cloud --> ipad --> streamer --> amp/speaker/sw
Try for this :
Digital Audio Block Diagram.pdf![]()
Notice the PC is gone and the iPad is only used as a controller - the audio never passes through it. This isn’t the only valid way to configure a system, there are lots of options and alternatives, but this is probably the most common.
Also notice the use of line level LP or LFE feed to the subwoofer. Any other form of connection is simply a compromise. Failing to HP filter the satellites denies all the benefits of bi-amping like better dynamic range and power handling; lower distortion from over excursion.
Anyway, the diagram is adequate for clarifying the discussion, particularly on the choice of interconnect - USB to a local disk attached to the streamer vs Network Attached Storage attached to the LAN.
If you are planning on building a substantial library of your own, the NAS is a far more scalable solution and using RAID, far more reliable as losing a disk drive does not mean losing the library as is the case with a single disk attached to the streamer.
