Hello everybody. Someone in the great dBpoweramp community is streaming to a Play-Fi system? Would you be as kind as share some of your experience?

The system:
01. Play-Fi (Klipsch) system.
02. 1 Luxul Router and AP: XWR-3150.
03. 2 Luxul AP: XAP-1510.
04. 1 Buffalo NAS LinkStation LS220D0202.
05. 1 MacBook Pro to access iTunes (mandatory because of iPhones, iPads and iPod Touch) built complete (metadata and music files) at the shared folder on the NAS.

The problem:
Play-Fi system can see and play the songs (AIFF files) but without most of the metadata, just the name of the song; no Artist Name, no Album Name, no Cover Art, no Playlists.
After some e-mail interchange with Play-Fi support people, they think the tagging is responsible. So, I decided to make a final test: I downloaded, straight from iTunes, 5 CDs each at a different file format and look at them through the Play-Fi system.

Results:
a. MP3: Song Name, yes; Artist Name, yes; Album Name, yes; Cover Art, yes; Playlists, no.
b. ACC: Song Name, yes; Artist Name, yes; Album Name, yes; Cover Art, no; Playlists, no.
c. Apple Lossless: Song Name, yes; Artist Name, yes; Album Name, yes; Cover Art, no; Playlists, no.
d. WAV: Song Name, yes; Artist Name, no; Album Name, no; Cover Art, no; Playlists, no.
e. AIFF: Song Name, yes; Artist Name, no; Album Name, no; Cover Art, no; Playlists, no.
That’s why the tagging possibility makes sense, do you agree?

The question:
Is there any special kind of tagging and ripping from dBpoweramp to “Automatically Add to iTunes” folder in order to keep AIFF files on iTunes and at the same time viewable and useful on Play-Fi?

Thank you very much in advance.
