Richh Posted January 1, 2014 Share Posted January 1, 2014 My current setup is a Mac Mini using iTunes, Apple TV, optical out of Apple TV to Marantz 7400 receiver. I can play CD's that I ripped using AIFF and they play fine. I downloaded an AIFF 24/96 sample file from HD Tracks and it also plays fine. I then bought and downloaded an AIFF 24/96 album from HDTracks. It plays ok from speakers connected to the MacMini, but when I try to play it through the Apple TV, it just plays a few notes of a song and then the audio cuts out. Does anyone have any ideas as to why? Thanks, Rich Link to comment
mwheelerk Posted January 2, 2014 Share Posted January 2, 2014 Apple TV does not support 24/96 files. I believe the current version is limited to 16/48 "A mind is like a parachute. It doesn't work if it is not open." Frank Zappa Link to comment
wgscott Posted January 2, 2014 Share Posted January 2, 2014 Even worse, it first down-samples it to 16/44.1, and then resamples it to 48 kHz. The reason it cuts out is that the buffering is inadequate for the big files. Can you use an optical connection between your mac mini and your receiver? Link to comment

I'm new to storing and playing files on a computer. In the past I just played CD's. I like the convenience of ITunes and being able to rip my CD's and play them through my receiver. The sound quality is not as good as playing the CD's directly. I thought using Hi Res files might sound better, so that is why I tried the 24/96 format. My Mac Mini is in another room, too far for an optical cable. What is confusing me is that all the files from HD Tracks sample album worked fine at the 24/96 sample rate. None of the files from The Joni Mitchell Blue album that I bought worked. I was looking at a product from NAD called the Dac 2. It is advertised as supporting 24/96. This product has 2 boxes. You connect one to the USB port on the computer and the other connects to your receiver. It has it's own wireless connection between the two. Would this be a better solution then using Apple TV? Will I still be able to use ITunes to manage my music files? Link to comment

I'm interested to know more. Paul Link to comment

If you are not thrilled with the sound of iTunes I recommend you trial a software player like Pure Music or Audivrana which can work in conjunction with iTunes as your library manager.

Richh Posted January 11, 2014 Author Share Posted January 11, 2014 I replaced the Apple TV with an Airport Express ( older version) and the 24/96 files now play great. Music that is ripped from CD's sound much better using the Airport Express. The brittle, bright sound from the Apple TV is gone. My music now sounds as good as when I play the CD's directly.

Bloodwound Posted January 12, 2014 Share Posted January 12, 2014 I may be wrong but I thought it simply sampled everything to 16/48. I was unaware of any other sampling step in the process. Airplay is hardcoded to 16/44, then the atv resamples 16/44 to 16/48 Yay! Link to comment
woodford Posted January 21, 2014 Share Posted January 21, 2014 might try a bluesound node. it will read your iTunes library, and stream up to 24/192 to you marantz, toslink out. Link to comment
