Better CDP or network player?

In the same boat a couple of years ago, although I didn't have more than a handful of SACDs. I am still very happy with the decision I made to go to a server. computeraudiophile had much helpful info from those who seem most informed on the topic. I went with a Synology NAS, while a number of others are also happy with QNAP servers. Err on the high side as far as #bays and overall size. Be sure to research backup options and my sure what you want to do before you chose RAID option during initial setup because it's a huge hassle or impossible to change it later. 
For hard disks I went with the WD Red drives which seem to be the far most popular and reliable at a reasonable cost. 
For network player I got a Sonore microRendu which presents a tremendous value and offers very high flexibility to use it with streaming apps like Tidal, and a variety of control apps. I use Lumin player app on my iPad to select my music. I suggest reading Chris Connaker's two part review on the microRendu to get the whole story enthusiastically, but accurately reviewed. There are many posts on this product here and elsewhere. FWIW, the Sonore guys are amazingly quick with inquiries about setup options and support. 
I've been told by many who regularly listen to much more expensive setups that mine is right up there in sound quality and user experience. Pretty affordable and well within your budget, even if you need to buy an iPad. 
Ripping CDs to store them is a tedious one time process, but well worth it. Ripping SACDs is another story and only a few ways to do it. There's much already written on it, I'd spend plenty of time ready what's already here and on computeraudiophile if you need to do that.

Listening to Beck's Morning Phase on it as I type :-) Cheers,

@shadowcat2016 ,
A couple of things:

Schiit Yggydrasil certainly DOES play hi-rez. So do most of their lower priced models. Correct, it doesn't play DSD. Because they don't believe DSD sounds better.
I can tell you that ripping SACDs to a server is a huge PITA and can only be done w/a few players such as old Sony Playstations and a couple of Oppos. If SACD( which are DSD discs if you didn't realize) is a big part of your collection or plans then get a cheap SACD player like a Marantz for spinning them.
But the majority of most people's listening  is 1) red book CDs, ripped from PC/Mac into a hard drive(hopefully a network hard drive(aka NAS - Network Attached Storage), 2) hi-res files in all the other file types(collectively known as PCM file types e.g. 24/96, 24/192 even 24/48) downloaded or copied from another drive and 3) streamed files from the you play from subscription services like Tidal, Roon, Spotify etc. 
Granted one box solutions are appealing for their simplicity. The same way receivers are vs. separate preamps, phono stages & power amps. If you seek the best sound quality for the dollars at almost any price point, then separates are the way to go more so with digital audio than almost anything else. Why? Because digital signals are very susceptible to electrical noise and interference. Spinning discs and their power supplies add noise. Storing the files on a NAS drive in another room makes it quieter. If you can't wire ethernet cable into the audio room, you can easily use wifi adapters that turn all the copper wiring in your home into wiring to pass the signal from your router & NAS in one room and your dac and audio gear in another. 
The other problem w/one box solutions is that if(when) the transport goes, you lose the investment in the whole thing. 2 years from now and every 2 years later, when dacs are better/cheaper than before, you might decide to upgrade. Many of the recommended dacs and others are upgradeable just by changing out a small board. 
FYI many of the devices use USB, which inherently carries power on one leg and signal on another. Many companies have made great strides in recent years to separate the signal from power to reduce electrical noise. If you don't pay attention to this aspect, and get a network player, cabling & dac that deal w/that issue better than most, you probably won't be satisfied musically. 
For the same reason(electrical noise) a network streamer built with a tiny board and small power supply sounds better in 95% of the cases than a windows or mac operating system computer running tons of processes un-audio-related, with a large power supply that let's noise into that tiny fragile power leg of your usb cable. 
If you invest a bit more time to learn about the pros and cons to some of these recommendations you will get amazing sound a far price.  I evolved from:
 A) Mac with attached hard drive running special audio software(Audirvana+, and the other top packages) to 
B) an Oppo player into a better dac, and then to
C) a mRendu network player in the listening room, a NAS in another room storing files, an iPad letting me control music without wires nor power supply interference. 
The latter option is in a completely different league at about the same price. I download high res files using my macbook or pc, save the files directly to the NAS(it's just another letter drive), rip CDs from the library the and save them on the NAS the same way, and don't use the computer when I listen at all. 
Other than for convenience, I haven't heard any one box player sound better than this approach (not just with my specific gear), and I haven't heard any arguments that logically explain why it would be better. 
"I have x and it sounds great" isn't enough of a recommendation. If you haven't compared the approaches you need to read up to understand why almost the entire community on computeraudiophile prefers that route.  Cheers,
Spencer

Bryston & Vandy is a great combo from two of the credible, most solid supportive companies in the game for the long haul. Smart, safe choices.

To address your questions in order, first, yes USB can be troublesome but in the last few years much progress has been made. One of the things I like about Sonore network players is that they come with a short(~2in.) USB hard connector included. The microRendu is about the size of a pack of cards or cigarettes. Place directly behind your dac input with just the long hard between player & dac. You can always upgrade later to a fancy little cable(e.g.4in. of silver wire) for ~$100 if it suits your fancy, but you probably won't ever feel the need. The approach minimizes USB trouble without spending extra on 2-headed cables, isolator boxes or other things that attack the same noise issue w/varying approaches. 
The PC running A+ or Jriver is certainly viable and sounds pretty good. Why I left that setup (mac mini  w/A+) is because my 3TB external drive was about full, no room to connect another. The power supplies for both mac & the external drive add noise that is connected directly to the dac by a longer USB cable. Not ideal, but okay. 
Think of the spinning mechanical drive being in another room -advantage. Think of a tiny power supply vs. the bigger one for pc - advantage. Think of stripped down Linux operating system only running audio vs. WIN or MacO/S running a hundred processes to monitor everything from viruses to video to screen settings. - advantage. Think of freeing yourself from constant O/S security updates and planned O/S obsolescence - advantage. All reasons to consider dumping the computer for a single purpose lower power player that gets data from an expandable disc NAS located in another room.  
You can always start w/the PC dac, start ripping your discs get started and switch to network player & NAS later with same dac. I wouldn't suggest that, but since you already have the PC it's a cheaper way to get started. Maybe you can find a local w/ NAS/networkplayer and bring your pc over there and listen to the difference. I did that and it helped me decide to dump the mac. Cheers,
