Replace my Auraliti

A Lumin is also a streamer pretty hard to get a file player that isn't also a streamer. If you want something cheap try a Node or a used Auralic Aries Mini if you can find one.

Any of the Oppo players will read files off your hard drive and either use the internal DAC, or output SPDIF to some other DAC. The only drawback is you need a TV to view the files on the hard drive, but you may like that way better than an iPad or phone. The remote on the Oppo is used to do this. My friend uses this method and swears by it.

Get this - HOLO AUDIO RED Audio Network Player

and use either Moode Audio or RoPieeeXL (which are popular audiophile-focused Linux distributions you can install on the Red's microSD card), you can typically connect a USB hard drive or flash drive to one of the USB-A ports on the back of the Red.

The software on the Red will then be able to mount and access the music files on that external drive, allowing you to browse and play them through the Red, sending the digital signal to your DAC @paulie123 

As far as I am concerned, it is the software as much as the players features that matter. Though there are differences, all of the name brand streamer/players sound excellent. Check out what features you want (i made an excel chart) to compare the players in my price class) and compare. Then check out the software. If you want Roon, make sure it's compatible. I didn't want Roon so the manufacturer's software was critical. I'm not a computer nerd, so players that depend on 3rd party universal programs (psaudio, Holo, Denafrips) were out. Do you use an iPad or Android tablet (not all the software work on both.) I ended up listening to the Eversolo, the Blusound and Auralic Aries and Vega in my system. Which I bought doesn't matter, you'll want to make that choice with your own ears. PS: If your dealer won't give you a home trial, shop elsewhere!

I used to have the Auraliti PK90 back in the day. Great player for that era, made even better when I added a linear power supply. On the downside it could be fussy and didn't always work 100%, even with the simplistic functionality it offered. I put up with it for a long time because I felt the sound was quite good. When it started acting up as it seems yours might be doing, I figured it was time to move on.

Even though I felt the Auraliti was one of the best sounding options when it launched, there are so many more new devices these days that will sound at least as good or better. 

Not sure your budget but I would look into Auralic, Innuos, and Lumin as those are all great options. Plenty of second hand models out there from each brand as well.
