Whether or not a NAS is appropriate depends on your usage patterns. Many people prefer to use a small, low-power, always-on NAS to stream audio and video throughout the house instead of using an interactive laptop or desktop computer to do it.
That's a separate issue from using your 80.3's buggy DLNA client. You might want to consider reporting the problem to Integra so they can fix it. I'm assuming it's something that could be improved by a firmware upgrade, of course. Rumors are that there won't be a new top-end pre/pro this year, so they might be motivated to improve the 80.3's firmware-based features to keep it competitive.
Well - i spoke too soon. Although the 80.3 display looks almost identical except per my post, the same file is being handled differently.
The key last night was using the "Display" button on 80.3 remote while the music was playing. Hitting "Display" changes what info is shown.
The file in question is a 2 channel music WAV at 96/24 on my Windows 7 laptop hard drive.
When i use my iPad DLNA controller to send from laptop directly to the wireless adapter plugged into 80.3 Ethernet port, and then i hit "Display" on 80.3 remote, the 80.3 displays 96 kHz / 24 bit.
But when i use my iPad DLNA controller to send from laptop to $80 Panasonic DMP-BDT320 Blu-Ray Player which then sends PCM over HDMI to 80.3, the 80.3 display shows 44 KHz / 16 bit.
On page 39 of Blu-Ray player, Specifications, there is a "File Format" table and for WAV, there is:
"Maximum sampling rate: 48 kHz/16 bit"
I did not know PCM could be altered before being sent over HDMI but i guess the panny Blu-Ray player doesn't like heavy WAVs and so somehow it downsamples it.
Back to the drawing board.
(Maybe 44 / 16 is good enough for everything - don't even know if i can hear the diff
