No luck, I have turned off DAC charging as suggested , problem persists. USB port at MacBook Pro not enough power to drive WM1A DAC ?

One last thing to try is a SMC reset on your Macbook. If that doesn't do it, then you may want to stop by an Apple store for help.

Is 3.0 Safe and better? thanks in advance wich link did you guys use?

I don’t know what you mean by safe, but I and others have experienced crashes with 3.0 and have never had crashes with the older versions

Nice, do you know if someone had any issue from volume capping when upgrading?

Mine is an EU unit that I have changed region on to uncap and this has never been affected by fw update including to 3.0

BTW I had a chance to try Project K-WM1 mod. It is perhaps the closest thing to 1000SS without needing to pay such kind of pricing. For me it took away the sound of WM1A, and gave more resolution, however for those who love the sound of 1000SS, getting a second hand WM1A and getting it modded works out 60% cheaper than getting the 1000SS.

I have a WM1A with the K-mod. It's certainly nicer than the normal SQ, the bass has slightly more oomph and texture, plus more resolution. Sounds great with FW 3.0. I'm looking at getting further mods via WindowsX by upgrading all internal caps and resisters too to see where that takes the SQ. I used to have the WM1Z which was amazing but it got tiresome carrying it out and about, so went back to the lighter unit and want to see how far these mods can take the SQ.

Just had my second 3.0 crash, this time playing on board flac, first time was in usb receiver mode. 3.0 does seem rather unstable, not like Sony at all, never had a crash before with ZX2 or 1Z. Wouldn’t be so bad if it didn’t take 20 minutes to create the database after a crash. Will go back to 2.0, don’t really need any of the new features, and the wait for 3.01 to fix the bugs

You know what's strange?

When using BT receiver on the 1z, with Tidal or other streaming apps... If I turn the volume on my phone to max. The 1z is overall louder vs direct file use.

So when using direct file for the same song and format. I stay around level 50 depending on track.

When using by (same file/song) I can't go north of 30 to 35...just too loud.

How come?
