From separate streamer and DAC to al-in-one suggestion

I will use it strictly as a Roon endpoint

Might consider the Bryston BDP 3.14.  Especially if your using Roon.   

I just have there dac-less BDP-pi and it makes a great Roon endpoint.

REview of the DAC which is basically whats in the BDP 3.14 streamer

What about the Teac UD-701-N?  I believe there are some people very enthusiastic about it.

Budget would be in line with the examples I had been eyeing so under $5k

You’ve got a nice tube DAC, and if you like its sound I think you’re gonna be disappointed with a DS DAC.  If that’s the case I’d look for another solution. 

An all in one is the level headed way to do it. Just like getting a well sorted CDP, you eliminate an extra box, cabling and all the ways added noise can find it's way in. Timing issues should go right out the window as well.

As for going for one with a AKM chip, I can wholeheartedly approve that move. I don't stream but my Technics SL-G700 SACD player is simply sublime in presentation, presenting an almost analog sound to the music that's so far from the other digital players I've had that it still amazes me. 

The only caveat is it will take a good 6 weeks to break in and there will be times when you're wondering when it's all going to happen but when it does, it's a beautiful thing. There's a reason they call it their Velvet Sound chip. All the positives of digital and lots of that analog ease. Good luck.

All the best,
