Sound quality of shared iTunes library wireless

Hi Everyone,

I hope this isn’t a dumb question, but here it is. First a little background.

In my two channel system I have an old iMac serving up my music files via a Schitt Bifrost DAC. I uploaded all my CDs to iTunes in a lossless format (AIFF) and they are stored on a 7200 RPM external firewire drive. The old iMac has a small hard drive and can’t handle my music collection. I have been super happy with this and it was a big step in sound quality over my old Rotel CD player.

I also have a spare MacBook Pro with a bigger drive. Recently I copied the entire music library to it’s drive and have this upstairs. To be clear, the Macbook has the same exact iTunes library with the same lossless files.

Today I was playing around and accessed the MacBook’s music library from the iMac via my home wireless network and iTunes sharing. I compared a number of the same tracks - from the connected hard drive and from the shared library wireless. It *seems* to sound exactly the same, but I find myself second guessing and imagining things. So, that is my question. Does it sound the same? Should it? Since they are the same exact files, it seems the only limiting factor is the speed of my wireless network, right? There is no compression or any other funny business via sharing… or is there?

I realize that if I can’t tell, what does it matter, but some of you guys know everything about this and I am curious. Plus, I have other uses for that 2 TB drive and would like nothing more than to use the iMac to access my music wirelessly like this.

Thanks in advance

I recently picked up a DAC and am now using iTunes on my PC via an Apple TV as a source. I have been unable to tell a difference between the DAC and my CD player. Even knowing the Apple TV has issues from an audiophile perspective I can't hear a difference.

I think you are on to something.

It all boils down to your view of the digital side of audio and your physical ability to hear the differences. In theory, if the data is transmitted to the DAC bitperfect then the results should be identical.

In the case of my Apple TV, the data gets converted to 48kHz which is the TV standard so I know that in theory it is inferior compared to even an Airport Express that converts to 44.1 kHz, but I still cannot hear a difference in my system. I am sure that it may be possible to hear the difference in some systems.

To clarify, the digital files are being fed from the same computer to the DAC? If so, you should expect identical playback unless there is a wireless glitch in the sharing process in which case you may hear the music drop for a split second.

What is the gateway to the DAC?
