My 2 cents.
Audeze LCD2 rev2 > Schiit Lyr w 1964 Amprex USN-CEP > Schiit Bifrost.... S/PDIF Optical >MacBook Pro Retina
Mac Mini with Promise Pegasus R4 4T RAID.
I have not tried Audionirvana Plus.
All the others ..yes.
I have the full license of Amarra for my room system and I like it.
I purchased another license for my can system until I discovered it doesn't work with shared libraries.
Sonic credited the purchase.
This is a big problem because I can't get iTunes to create a local library from a remote NAS. Some of the content is index and some isn't.
I can't put 1T of music on 4 Macs
BitPerfect sounded OK to me but has the same limitations with shared libraries.
I thought that Pure Music had a very harsh sound compared to Ammara.
Lastly, Fidelia. IMO the music sounded neutered. Mush. All personality was gone.
I've been too bashed in to try Audionirvana yet.
Will it work with streaming?
