Reality check please

I have been running Volumio for several weeks now on a Pi4 with HiFiBerry DAC+Pro. All is well.
There are a few things I’m working on making work better, but it is working well enough I’m looking to expand the system.

Please tell me if this should work the way I imagine before I sink a lot of time and a few more $ into it.
First I will upgrade to Virtuoso to allow for multiple devices.
Next I would build (2) more devices- I’m planning to use Pi3 with HiFiBerry Amp2.
the Amp2 is described as a DAC+ with integrated amp.
I have 2 pair of speakers laying around that I plan to use with these.

I’m not (for now) concerned with synchronous sound in multiple rooms, just to be able to have music in multiple parts of the house.

Now the big question- Will the remote devices have access to my music library which is on USB drive mounted to the current Pi4 system? If not, would a NAS solve that?

Thanks for setting me on the right track.

Volumio exposes the local USB drive as an SMB share, so I’d imagine a second and third Volumio installation could use that share in the same way it would use an SMB share on a NAS.

UPDATED Question:
In another thread I saw where a user who was upgrading to Superstar was advised to cancel his Virtuoso account and start a new account as Superstar. Is this correct? If so, and I do that, will it solve my problem of old playlists I can’t get rid of? I’m guessing they would go dormant along with the cancelled account.

If I have that correct I’ll stop worrying about the playlists as it will resolve anyway.

Thanks for any clarification.

I have three Volumio systems as you describe - 1 with Hifiberry DAC, USB hard disk, into a standalone amp to drive the living room speakers, and two others with Hifiberry AMPs driving old speakers, one system in the loft and one in the bathroom. It works fine, you can’t synchronise playback in all three zones (unless you upgrade the MyVolumio) but you can play different things all running off the same USB hard disk. The systems are all aware of each other too so you switch between playback zones in the UI.

I’m in the process of getting a paid MyVolumio account though, mainly so I can stream Tidal stuff in addition to my USB of ripped CDs.

Joew- Thanks that is just what I needed to hear. I have two Amp2’s on their way.
I think I’ve marked this “solved”

Joew Thanks for your help !

So far so good. I have all three units working.
Pi4 HiFiBerry DAC+ Pro SSD library on USB “Volumio”
Pi3 HiFiBerry Amp2 “Volumio2”
Pi3 HiFiBerry Amp2 “Volumio3”

I am able to play Webradio from all three so that much is good.
Now I would like to be able to access the library from Volumio2 & Volumio3.

I’ve tried adding the USB drive as a NAS in the Sources menu.
I’m really just faking my way here so if this is the wrong approach please point me in the right direction.
I used the IP address for Volumio and the mount location of the USB as the path.
I’ve checked the documentation and I don’t see specifics. I tried the “auto detect” and it didn’t see any networked drives.

I can see the drive from my laptop on the network so I know its accessible. I just need to know how to tell volumio on the new devices where to find it.

Any help is appreciated.

\\volumio\usb\whateveryourmusidirectoryis is the UNC or CIFS path to the share.
