Computer, CD transport or Network Player?

So it looks like either of these setups can work IF implementation is top notch. I'm not much for Spotify, Pandora, etc. because I like to listen to my own music. If I listen to an album sample & like most of what I hear I buy the CD. Would an SSD computer be better than the HDD I'm currently running? Does a network player with storage have any advantage over an SSD computer?

I would think a non moving parts transport would be superior. But just wonder about the pros and cons of an SSD versus network player. How would a DSD DAC fit in this mix? Would it increase SQ?

After lots of investigating my interest has been roused by PS Audio's DAC's, 1. DirectStream, 2. DirectStream Junior. Also impressed with what I've read about the exaSound e32 DAC. For all who are familiar with these DAC's I'd like to hear your opinion on them. My Calyx Femto came out in 2012 and as I said the sound is wonderful, but I wonder what's evolved since then and how might these newer DAC's compare. 

timlub (or anyone who can answer) how do you "optimize" your computer for superior playback. I always thought all you needed was a great DAC with a decent computer based media center like JRiver or Audirvana (and of course the rest of your downstream gear had to be decent) and it would give you superb music. Now I'm hearing music servers are superior to computers. Well I 'm happy with my computer (because it's simple) but now I'm curious about "optimizing" it. Suggestions?

So, everest_audio, I'm understanding a dedicated music server is superior in sound to a computer and the music server doesn't need a DAC, correct? How is that possible? And randy-11, I'm understanding optical or WiFi eliminates computer jitter problems and also doesn't require a DAC, correct? The DAC is the most expensive item in my system. It seems going this route would be complicated (and expensive) to transition to. And I would still need a computer to rip CD's or download music purchased online.

It seems I'd need to purchase
1. a network music player probably with an upgraded PSU. (Takes the place of a computer). Does the player automatically playback HiRes, DSD or DXD files at their original resolution? If yes, it would take the place of JRiver and HQPlayer, too.
2. a media controller (probably an iPad (I don't care for i anything) with an app to browse and control music playback). (Takes the place of a monitor, mouse, keyboard and JRiver and/or HQPlayer)
3. a Network Attached Storage (NAS) where all my music files would be stored (Takes the place of a computer).
I already have a (wired/wireless) WiFi network connection. Again, STILL I'd need my computer to rip CD's or download music. So I'd be trading 2 expensive boxes (NAS & music player) for 1 computer and 1 DAC (or would I still need a DAC)?  Also trading 1 iPad and app for 4 items-mouse, keyboard, monitor & JRiver). Is this correct? If not please let me know because this new technology is just so complicated to me. Please keep in mind my number one priority is superior sound quality.
