Streamers - Can any host files?

The Vault Icon is supposed to be great.  I have a  Vault 2i.  It's a great machine but I paid $1199....  it's been out for 6 or 7 years.   I mostly stream but I do have hundreds of CDs ripped to its drive.  But I also have a 2TB drive with music that I plug into my Vault or Aurender.  Most streamers can handle up to 2 TB USB drives.  Some do not have that limitation and can address 4TB or more.   

There is a 4 1/2 year old Vault 2i on Audiogon for $550.  

I used this for Ripping and Streaming Presto for 4+ years.

Or, for $1,100 you can get it in white, open box.

FWIW, I used external SS and HD drives for years, bought an Aurender N200 and took advantage of the internal SS storage ability. The improvement in SQ was immediate and  startling. Now the ext drives are for backup insurance. 

I bought a Wiim Ultra.  You can attached a usb drive and run files off of it.  Very easy to use, great software, i use mine with an external DAC but the built in one is decent.  Around $329 but often on sale.

As others have suggested, you can hang a HD off the back of a streamer to access your ripped music. Another approach, if you have wifi (And who doesn't anymore?) is to hang your HD off the back of your router. Then you can have your streamer "find" your files that way. 

An advantage to this is that you can rip CDs and copy them to the HD via wifi and keep your library up to date. Additionally by using this method your files will be available to any other devices on your network. 

Happy listening.
