Melco Audiophile NAS

[Donuk]

Go for it. I have had an N1/A since they came out. No issues, continuous use, no failures.
Don't use Twonky, and be sure to disable it. Minimserver works fine, and survives Melco firmware upgrades.
I use mine in Raid 0 configuration and though this is polemical.
Always keep a separate NAS /hard disk as emergency back up.
See Martin H's report on about page 6 of this thread.
I prefer Lumin, but the Linn apps work fine. I have no experience of using the Melco with USB output but there is lots you can do with it.
Good Luck
