Of course -- accompanying Atkinson's bench test report there's a full-fledged subjective review, by some Stereophile prat.

Instead of using my Nano, I'm using an Apple TV to listen to music. The Apple TV is connected to my receiver via HDMI and the signal to my receiver is PCM. I'm guessing that my receiver's DAC is being used since the incoming signal is digital. Unlike the iPod dock unit for my receiver, Apple TV displays the album art and song information on my TV! And in 1080p. So far, I like using Apple TV more than an iPod dock.

Happy 4th of July everyone!
cheers!

my friend says that the ipod sounds like crap compared to CDs because the ipod only has a 1bit DAC as opposed to a 24bit DAC in his headunit.

But the 1-bit DAC has a higher sampling rate, SO THERE. Your friend loses the number game.

The iPod does not use a 1 bit DAC, it has a stereo codec with "24 bit" multi-bit Delta-Sigma DACs.
And I don't think your friend understands how a DAC works. That a DAC is labeled 24 bit only means that it accepts 24 bit signals, it does not mean that it works with 24 bits internally.
They usually (like the one in the iPod) work with just a few bits, but at very high speeds.

So both the iPod and your friends head-unit use "24 bit" DACs, but that does not tell us anything at all about their sound.

Sorry if this was already mentioned, but the only product made to bypass the ipod dac and analogue output is the Wadia unit that runs about $350, otherwise...

Having said that, I will be making a DIY iPod dock-to-RCA cable just for grins. ;-)

its the best ipod in my opinion i got the new 160 gig ipod and it sounds like **** compared to the 5.5 g
