pure ipod dock

What are folks thoughts on using this pure i20'dac with a tube headamp? Is it going to perform better than the iPod?

the pure i-20 dac has sound quality that is superior to the ipods internal dac. if you have ripped your cds to your computer and synced your ipod using the best quality settings then the i-20 will perform very well when compared to a good cd player. i am not capable of using all the descriptive language to describe what "better" sound quality means. self explanatory ha. good luck. i am still waiting for a comparison between the wadia and pure [with digital out setup] if anyone who is familiar with both can help....

Can anyone explain how the pure dock allows volume control on a supposedly all digital signal ???? How is that possible ???

your mind is stuck in the analog domain method of volume control which you are trying to attach to a digital signal & are getting totally confused!! ;-)
Digital volume control has been done by Wadia since they were founded back in 1988! You do digital volume control by increasing/decreasing the bit width of the digital signal - longer bit length = higher volume, shorter bit length = lower volume. Hope that this helps.

Sorry, yes you are right, the Wadia doesnt have a DAC,it only allows you to hook up to a DAC and avoids the use of the inboard Ipod DAC. I could have just looked up at my set up to have seen that. Its been a while since I hooked it up.
