pure ipod dock


I have to tell you this dock is absolutely great. After 3 days it gets better and the built-in dac pretty dam good. Makes my ipod a new source in the living room. Even in the he-man room not too shabby. Also bypassing the internal dac and using an ACK or any non over sampling dac I had it sounded better. Plugging into a linn sc player sounded very good and so easy to use . The video output is very cool, a great extra. I never though I would say it but at $100 it rocks blows the I 70 out of the water. A keeper

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.
The PURE i-20 has several outputs: analog stereo from its internal DAC, digital coax, digital optical and component video. The most interesting one is the digital coax because it allows you to set up a high-quality connection with an external DAC. It bypasses the iPod's internal converter and headphone amp and delivers a signal that sounds just as good to me as my best Redbook transport's.

Of course the Wadia unit has been able to do this for a while now, but at a higher price. There is news of a Cambridge Audio dock with a digital output as well.

The i-20's internal DAC's output is not as high-quality as the coax digital output but it is respectable enough, sounding at least as good to my ears as an Oppo 970 player.
