.....its just not bit perfect, that's all. Several well known DACs upsample as their norm.

 

Benchmark media, makers of the venerable DAC1, have conducted tests that have shown that the upsampler within iTunes (NOT coreaudio) on the Mac is very good, too:

The DAC1 also resamples everything to 110 Khz. 44.1Khz data goes up and 192 Khz goes down.

The above is a good point - also note the posts near the top refer to the TV2, and the TV3 may be different.

 

There are reports of differences in SQ on the web; and memory and the processor differ between the 2 models.

I just hope I don't have to garden or mow lawns...

 

resurrection due to controversy on another Apple TV thread - some think it is the work of the devil

 

BTW, TV4 doesn't have an optical audio output

Yes, video also.

 

There is a previous thread on here about the TV3 and the conversion of 44.1 to 48 -- the gist of it is I see no reason why that would harm SQ.

 

but I'm open to new information
