Hi, there

DSD256 will be Native DSD first on Windows Platform. And after, we will implement Our PureDSD on Mac platform as well…

DSD256 is via DoP or do we have a DSD Native support?

Because I don’t know any software can support DSD256 via DoP right now (is there any?). With DSD Native, yes.

Do the Pulses come with a card describing the proper sequence to use to connect, power on, plug in headphones, and play music without risking blowing your phones? Can someone post that info here? Do I also recall that you aren't supposed to leave any headphones plugged into the pulse when not in use?
While I seriously doubt I will get my stuff by the end of August as promised in the new shipping schedule, I don't want to destroy my headphones when I get the Xfi.

No, there are no instructions included but this video will explain everything.

As for not blowing your headphones I'd unplug them when you power down if you're worried. If you leave the Pulse on it won't be an issue.

I do not leave the Pulse on all of the time... too long between listening sessions. I typically turn it on an hour or so before listening. I then boot the PC. It never detects the Pulse. I have to turn the pulse off then on, then it is detected. I then plug in the headphones.
 
Now for just running things in, I have let the system go for several days. It continues to work properly, whether using the XLR balanced out or the SE socket... or both.
 
 
BTW, I have fired the pulse up from cold with headphones plugged in, switched it off and on for PC detection.... still no problems!
 
I also connect the balanced line out to an H10... which works while either or both of the HO connectors are in use. No problems, no thumps or transients that I can hear... certainly nothing that would damage headphones.
 
If there is any concern, fire up the pulse, make sure it is detected by the source... wait a few minutes, then connect headphones. Based on my experience with my unit, this is really not required to protect the transducers.

Unfortunately I have neither a light speed nor an LPS.
I know there are issues with the Pulse not having buffers or whatever, and at this point I have read enough to be afraid to use the Pulse at all without safe handling instructions.

Not that I have it mind you. Was supposed to be in hand months ago and I am pretty sure that all my tickets just got me moved to the end of the queue.

The Geek Pulse Setup and User Guide is available on our support site and has been for a while. The Installation section provides the proper steps for connecting and powering on the Pulse.
 
Please read through the whole Guide, it can be found here:

Guys.. need your help. Can anyone explain the basic difference between a vanilla pulse and a pulse fi ? Thanks!

The Pulse Fi is the Standard Pulse with femto clocks and upgraded amplifier.

Maybe I'm just crazy, but I leave my Infinity on at all times with my Audezes plugged in and the volume at -127.5dB (the lowest it goes). Have never had an issue of any type - no spikes, no sudden volume changes, etc. Seems like the new firmware is much more stable although as always YMMV. Also one of the many good things about the Audezes is that they can take a ton of power!

I'd be nervous about leaving my headphones connected 24/7. If you have a power outage you're going to get that famous Pulse "we don't need no relay" spike through your headphones when it comes back.
