NAD M10/BluOS - Please Help

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......

Seems like a lot work to enjoy playing music.
Wouldnt it be simpler to have everything on one server that automatically backs itself up?  Servers can be accessed remotely so use the home server while at work.
  For portable listening, when you can’t access the server, 1TB on your phone should keep you going for a while.  Remember, you can only listen to one piece of music at a time.  However, I know what you feel.  When I am traveling, with 512 mb on my phone plus streaming, it’s always the music that I can’t access that I hanker for...
 I had about a TB on my Bluesound Vault2 before I backed it up to my Synology NAS.  I still use the BluOS , along with Bryston Manic Moose for my Bryston BDP3.  The Blue OS app tells me that my music resides in 2 folders, the NAS and the Vault2.  I just open the NAS

Yes, I have everything on one server.  Backups only take a few minutes because I only need to backup the changes, not the whole library.  While I can access the Server remotely, there is no need to.

I'v had a dedicated music server for 18 years now since the release of the original Slim Devices Squeezebox.  Today, I have 11 streaming devices, 10 of which can access the music from my phone.  My whole entire music library is also on my phone.  The one streaming device that uses the music server is the one device that I use the least for streaming.  So, wouldn't it make more since to just change that one device and then get rid of the Music Server all together?  After all, I use the phone to control all the devices anyway.

No matter how I try to justify it, I think that dedicated Music Servers are so 2010.  Currently I have a 1TB memory card in my phone; soon it will be 2TB.  With my Phone, Chord Mojo and Audeze LCDi-4's, JH Audio Layla's or Campfire Audio Solaris I have a portable Hi-End rig.  I'm not worried about breaking or loosing my phone because it's insured.  Everything on it is backed up, and I'll be back up and running in a few hours.  That being said, my phone it always in a protective case and has a screen protector.  

If your Rig is working for you, great, no reason to change it, enjoy it.
