I use a Sonos connected to my PC. The only downside is leaving the PC on. When I have completely organized my collection, I might invest in a NAS for convenience.

There are some notes on the choice of SD card in the CT10 manual. They recommend SanDisk or Transcend, no larger than 400GB. Either way, your Apple computer (I'm assuming its a computer) shouldn't have an issue with the SD card's brand, size or file system - have you tried a different card...

I stand corrected! I haven't used my separate's in over a decade. I am going to fact check (e.g. Google) my memory on this stuff in future!

I see your point about the RIAA already in the pre-amped turntable. My thought process was going back a few years when the inputs would not (or rarely) have been equalized.

I am I missing a trick - how do you upload a image without using CDN. There is no Upload button?

A bit late in the conversation! To achieve the best quality sound, analogue record players and tape decks should use phono (for RIAA equalization) - that's pretty much what it was designed for!

I ripped my collection using iTunes. I use a Sonos to view and play them. My thought was that CD/DVD drives won't be around for ever, and I didn't want to lose a lifetimes worth of music. Also, Spotify doesn't have everything e.g. B-sides.
