Better CDP or network player?

I have been wondering about doing this as well. I have an older onkyo player that does sacd and has always sounded great to me  but it's about 8 years old. I have been looking at the Cocktail Audio x45. You can rip cd's and it has a phono stage so you can attach your TT and rip those to it as well. Only problem it cost $3000 though I have seen the previous model the x40 for $2000. Of course like everything some say don't use a single device but use network storage and stream from that because it'S easier to upgrade but like you I look for long term solutions as long as something doesn't go belly up and the idea of a single device which looks fairly simple to use appeals to me. Can't say how it performs maybe some with knowledge of a device like this will chime in. 

With the SA14s1 you can't download your music to the player it doesn't have an internal hard drive. You can connect a computer to it. You can use usb sticks and external hard drives but it looks like it would be a pain to use those since it plays files by date so you would need to basically fast forward through them to find what you wanted. You would need another device to stream from your network to attach to it.  Download the manual from marantz it explains what it can do. 

 Just for information purposes the aforementioned Cocktail Audio x40 or x45 is a one box solution. You can rip cd's or LP's to it's internal storage and play them back. You can stream audio over the internet. You can hook an external cd or phono player to it and play from those since it has digital and phono input to it's dac. You can hook it to an external large screen to view your library, it has an FM tuner for local station playback.  My familiarity with this is from my own resaerch in looking to move to storage and streaming. I am not recommending this unit I have no direct knowledge of it only using it as a reference there are other players that do the same things. Going the route of ripping with your computer and using network storage and a seperate player to attach to your dac is a good way and preferable by some especially if you have a good existing wired home network not sure how well wireless would handle hi res playback. The main reason I look more at the 1 box solutions is ease of use and I can't extend wired ethernet where my stereo resides. Whichever way you go try and read as much as possible about the different approaches and find one you would be comfortable with use, sound quality and economic wise. 

The thing about going the storage route that appeals to me is being able to access the music by looking through my library on my tablet or tv screen instead of search through all my discs. You can create your own playlists of say favorite songs from one artist or have it play random like a radio station. Then again there is  something about handling the disc as listening to the whole ablum which is why I would like to keep my player

Looks like a good plan. Win 10 has a built in dlna server not sure if it's used much anymore there is  probably better third party media server software.
