Hi Alex,
I had the same problem.... I purchased Amarra mini a couple of days ago and discovered the issue yesterday. I wish I ran into issues during the trial period but I hadn't...
It seems that the Amarra has problems if a name of the actual music file contains certain character(s). So far, I have identified that quotation mark(s) " in the name of the music file seem to halt the playback. When I removed the quotation marks from the name of the file, it played without a problem.
Also, FAQ in Sonic Studio's website indicates as a known issue that "There are still some issues with long ?le names not playing as expected."
I am not sure if there are any other issues that prevents Amarra from playing a music file. I hope not... I already have several hundred CDs (mostly classical) ripped and I would need to review and fix the file names...what a pain...
All such files can be played through iTunes, BitPerfect, PureMusic and Audirvana Plus without any issues.
Frankly speaking, I am very disappointed and I think this kind of problem is unacceptable especially given the very high price of the product relative to its competitors. I think an application should be able to play all music files with file name that an OS allows them to be named.
I will be contacting Sonic Studios... I hope everyone else who encounter the similar problems would so that Sonic Studios will fix this problem sooner rather than later.
