Wadia iTransport and Classic iPod's EQ setting


Hello,
I own a Wadia iTransport 170i, used with a 120GB iPod Classic and an outboard DAC via COAX digital cable.

When I change the EQ setting on the iPod, the sound would also changes.

To my understanding, if the iTransport takes the pure, unaltered digital signal out of the iPod (bypass the iPod's internal DAC), this digital signal should not be effected by the iPod's sound processor, but my experience proves otherwise.

Am I missing something or does the iPod processes the digital signal BEFORE it goes through its internal DAC? (That's why the digital signal extracted by the iTransport was effected by the iPod's EQ?)

Thank you very much for your forth coming explanation.

I just checked mine and you guys are right that the sound changes and I am using coax out of the Wadia into a PS Audio DL III. I don't get it but maybe the EQ is imposed in the digital stage prior to output. My new Alpine car stereo does the same thing but I didn't expect that to be the same as the Wadia transport. Still sounds good but that's because of the DAC IMHO.
I just got back an email from Wadia, and they said that the EQ was done before the DAC, and only volume and balance is after the DAC that's why the volume doesnt have any effect. They suggest to leave the iPod's EQ in OFF position.
The DAC in the iPod is not used with the Wadia. The EQ is probably applied during the decoding of the lossless file. You're getting your terms confused. DAC = Digital-to-analog conversion.
Sorry, nevermind. I interpreted Jaytea's post wrong (shouldn't post before coffee). Yes processing after the DAC wouldn't be heard with the Wadia.
Whatever, mine sounds awesome and I listen to my system even more now when I am around it. I used to play CD's with my integrated, now it's so easy to just place the iPhone for a charge and listen. My files are ACC 256 files but my DAC is set for 192 kHz.
