Power Adapter
One thing that has been criticised about the iD22 is the tiny power adapter. The manual specifies >1.5A and yet the one that they have supplied is only 1.25A. Some users on Gearslutz consider it to be underpowered and recommend replacing it with a more substantial one. I may consider doing this eventually. (What puts me off replacing it is my recent experience with other replacement power adapters, where the measured voltage was nearly 10% higher than it was supposed to be).

Phantom Power problem
The first few times I tried using a condenser mic, the iD22's phantom power was apparently not working. I never got to the bottom of this, but a few weeks later I tested it again and it was working perfectly and there has been no problem with it ever since. Weird!

Saving presets issue
Some aspects of the software GUI are not really up to standard. When you save a preset, you don't see a standard dialog box showing the presets folder with existing previous saves. And if you save a file with a filename that already exists it fails to save but gives no indication that it hasn't saved. I reported the problem. They replied saying that they were intending to correct this, but there have been no updates for nearly a year.

Patronising
I reported a minor error in the manual. The reply was a bit patronising, implying that I did not understand the terminology. I persisted and the next reply was "Apologies about that, it does appear to be a mistake". All good now.

Normally I hate it when people use forums for their personal blogs. But in this case I believe that this ongoing review might be helpful to potential iD22 users.

FURTHER UPDATE:

• The problem with the window not remembering its position was fixed with the next software update.

Thanks for the update Kev!

One absent feature that I wish had been included in the iD22 is clock sync. I recently added an 8-channel DAC and an 8-channel preamp/ADC, which are both now connected to the iD22, providing additional outs and ins. Unfortunately the inability to sync their clocks restricts the ways that I can use them together. This is one problem that I never anticipated.
 
But apparently Audient's new iD44 has this feature.

Shouldn't you lock on the adat signals? I suppose your other devices have to lock to the Audient and not the other way around.

Btw, i have a patch bay and love it. Much easier than crawling around on the floor all the time.

It would be logical to sync everything to the interface. But, as there is only one piece of equipment (Audient ASP800) in my system that includes a clock sync port and nothing else to connect it to, syncing is not possible.

Yes, me too. But why mention it here?

I was mentioning the patch bay because it really helps with my Audient asp 880 and rme ucx interface combo.

You don't need to connect the clock when using adat light pipe. The sync data is part of the data passed in the adat connection. So your devices will lock together, but your id22 is probably locking to your asp800.

Using the ASP800's inputs for recording is no problem. Neither is using the Aphex 141B DAC for exporting. Using them both together, without the ability to sync their respective DAC and ADC, is the problem. I get clicks in the audio when I do outboard processing, going out through the 141B and back in via the ASP800. The only way to avoid clicks is to bypass the 800's ADC.

I have line inputs 1-6 and outs 1-8 of the ASP800 connected to a patchbay. I have 2 xlr mic leads permanently connected to ins 7 & 8.
