NAD M10/BluOS - Please Help

So, I just picked up an NAD M10 Player.  I have a Crap Ton of Hi-Res FLAC/DSD stored on my LG V50 phone.  How do I access my music?  I don't use streaming services.  I have searched all over The Bluesound site and combed through the FAQ's.  I sent a support request to Bluesound and NAD, but it's been two days and no replies yet.  I have Googled the crap out of this but can't find and answers.  Please help.

I have the same LG phone.  I connected it to my preamp through one of those minijack cables from AudioQuest.  It sounds fine.  If you want to wirelessly steam from the phone you need something like AirPlay or Bluetooth.
Airplay is an Apple thing, so not supported on the LG v50.  Bluetooth AptX only supports up to 24/96.  So, that means my Hi-res gets down sampled; not acceptable.    Bluetooth has a  max range of 30 feet.  

There are many wifi streaming devices, such as SONOS, Play-Fi, ect,; it's a long list and I don't know them all.

I have multiple Play-Fi devices that support up to 24/192, but was looking for something more "Audiophile" for the Office.  That was my motivation for choosing the M10 because it supports 24/192, DSD and has room correction to boot.  Unfortunately, BluOS pulled the streaming music from your phone function for security reasons.

The DAC in the V50 is very good.  The output amplifier is just OK. I don't want to "hard wire" my phone to my amplifier because I use it for other things such as making calls, email, texting and general wasting of time.

BTW, they make Bluetooth receivers that you could plug into your preamp and get rid of the wire.  However, this might not sound as good as hard wiring.

Finally, I do have a dedicated music server, but I'm trying to get rid of it.  I'm the only one here that listens to music seriously, so no reason to have it anymore if the phone acts as a server.  Also, one less thing to maintain.  
I know the LG doesn’t do AirPlay, which is why I said “something like” in my post.
I also have a n AudioEngine BT DAC in my living room system, now going on about 5 years old so it probably isn’t the latest codec.  I purchased it so my kids can stream to their phones when they visit or when they house sit.
  I don’t use my phone much in my main system via the preamp for precisely the reasons you cite.  I use my phone primarily as my portable player and in the car storing files on an SD card.  I bought the cable to connect to my preamp as an experiment, and haven’t used it since that day .
  Your last paragraph baffles me a bit.  Are you putting all of your files on a micro SD card?  Why is it difficult to maintain a server?  Once you have bought and set the thing up, what’s to maintain?  I guess I just wouldn’t trust a micro SD card as being only form of storage in case I lost my phone, although if if’s backed up somewhere I guess it doesn’t matter..
  I use the Blue OS app with Bluesound Node 2s in my system, with a Synology server.  Does the M10 have a hard drive?
Sorry, missed the "something like"

I have a 1TB (don't ask) in my LG V50.  So, yes, I have all of my music stored on my phone.  I also have a copy on the Server, a copy on my main machine, and three backups, all on Solid State.  Also, the wife has a 512GB in her phone with her music that she listens to at work.

My big problem is keeping all the different devices and backups in sync.  I buy a lot of music, about 20-30 albums a month, and it has become a chore to make sure all the devices/backups are in sync, everything is re-indexed and all the metadata is correct.  As far as the server goes, not much maintenance other than making sure OS is up to date.  The whole process, including copying new music to backups/devices, takes about 2-3 hours a month, depending how bad the different operating systems/playback software mangles the Metadata.  I work on computers, I'm getting older, and I'd like to do other things in my free time.  The last thing a house painter wants to do on his day off is paint his own house.

For sure, look into the new AudioEngine BT adapter; it supports Bluetooth 5.0 and AptX.  Only $189.

The M10 does not have a Hard drive.  It has a USB 2.0 port on the back for an external HD.  I plugged a 2TB Samsung T5 portable Drive into it.  It took over 7 hours to index it and then promptly rebooted.  BluOS Tech Support recommended splitting up my library over three different drives.  No, I don't want to do that; more to maintain.

Bottom line is a want to downsize and simplify and get that monthly maintenance down to under an hour.  Eventually, I'll slow down on the music purchases......
