Ah, now I get it!Yes
I fed the Ipod 22.15 V and it didn't blow up.
At least not immediately, that is. I ran into some problems with the ipod later on that may or may not be related.
I now use a generic 12V wall adapter.No
I didn't use acessory detect since I didn't know about it at that time.
Though recently I did put a 1M resistor (21 to GND) into the original Ipod dock to get power-off on disconnect.
Also, I'm skeptic if the internal regulator is bypassed without acessory detect. Where do you take that from?
Because the similar Wofson Dacs only take up to 3.6V DC, some regulation has to take place somewhere even if you input the standard 12V.
Here are some further arguments, for it being safe to run the Ipod on >12V:
-There is a report on the forum of successfully running the ipod from >20V and no accessory detect was mentioned (You'll have to search for it I don't have the link).
-Naim sells a 24V ipod adapter called the iSupply, comercially and I couldn't google any reports of it blowing up Ipods.
- Most importantly: The FW specs definitely allow up to 30V and the Ipod can be run off FW without accessory detect.
I think these far outweigh my above mentioned suspicion, and you should be safe.
But it's your Ipod, so it's your decision.
