I have the previous 2006 9V version Micro Stack on loan from another local Head-Fier but I've been having some problems with the DAC syncing to my computer via USB using ASIO. Everything seems to work fine initially but after awhile it starts to tick loudly, kind of like a hiccup if you will. The music can still be heard underneath and power down both the computer and the DAC doesn't seem to work all the time either. It should be noted that when this is happening a ticking can still be heard at idle as well (when hooked to the comp).

I mentioned it to the owner who also noted he has had issues with a ticking when trying to get it to work with one of his transports, a DVD player, but other transports he uses he's had no issue with.

Anyone have any ideas what might be causing this?

Check your batteries. When they go down you can get some unusual noises & the DAC doesn't just quit working all of a sudden. It'll keep working but just sound really really bad for a while.

Last time it happened I had just charged the batteries so I don't think that's it.

Does this happen with multiple computers or just one?

I've only had the opportunity to use it on my home computer, Matthew uses it on his Mac's but with optical not USB.

Thanks Tyll!

Great, now my SN is exposed to the world, thanks Tyll.

Try this using AC power and NO batteries. If it works on AC power, then the problem is probably battery related. Either one battery is not fully charged, or it may be they are not making good contact with the clips inside the amp. If the battery clips are bent and not making good contact, then you will need to send the amp/DAC in for repair.

Otherwise it almost sounds like some kind of interference, maybe with the USB cable. A better shielded USB cable might help. If all else fails and you can't figure it out, please send it in and I would be glad to check it out for you.

Drop me an email if you have any questions.

Thanks Mike, I'll try those things.

A little more information, I tried the Micro Stack briefly at work this morning in OSX on an iMac without issue.

I doubt it's a cable issue at home because I use the same cable for my Pico without any issue.

My MicroDAC did not like it when it had less than perfect batteries.

HA! That's funny.
Enjoy The Swelling, Mike! ... and sorry about your wallet
