You have to remember that you're an early adopter guinea pig that LH Labs use to highlight any firmware and connectivity glitches, as it's inordinately more thorough and considerably less expensive to let users report problems than employing a specialist to debug usage peculiarities. It's crowdfunding baby!

Good suggestion -- it was on PCM and I tried bitstream for the hell of it.  I noticed no difference either way.

True -- though connecting device A into input B is hardly a usage peculiarity ... unless (from my standpoint) they only expected folks to use USB ...

  Have any of you guys tried using the Geek Pulse via non-USB connections?  It works nicely for me via USB, but in trying both SPDIF (both ports) and Toslink, things didn't go so well.
 
With SPDIF, the dropouts are occasional, but enough to be annoying -- in this case, the Pulse was connected to a Blu-ray player I have.
 
With Toslink, I connected from my Macbook Pro using a Toslink cable and a mini-Toslink to Toslink adapter.  This cable works very nicely with an Audio-gd NFB-12 I have, so I have no reason to believe the problem is either with my laptop or the cable.  In this Toslink case, the dropouts are so severe as to be unlistenable -- things are dropped out more than they're playing.
 
Anyone else have any better luck?

 
Just did a quick test using coax-out of my X3 and DX90.  Worked ok except very annoying that I had to reboot the Pulse to go back and forth between the inputs.  I'm not sure if this is a known issue.  Another thing I noticed is the sound was decidedly less to my liking via coax compared to USB (with the LPS).  Coax had more of the negative sound characteristics that I associate with Sabre chips (brightness or glare - not sure what the right word would be).

Hmm...they already had some spdif issues with the standard Pulse therefore i would have assumed "some lessons learnt".

Not sure when it was published, but the new Q2M chip perk is back up until 6/3/15

uzi you have one of the xfi from the early batch where they said they had to throw all the pcb away because of impedance problems causing toslink/spdif to not work right?  and they only had 80 that worked and they said they'd test them for a long time to make sure the spdif/toslink kept working?  looks like they didn't test them long enough

The HPA V181 arrived today. I've been listening for a few hours and I have to say that the MBP > LPS4 > GO SE (TCM) > HPA V181 is an excellent combination. Seriously impressive. Now I'm super excited to eventually get my hands on the Pulse X Infinity and tube HPA combo.

On my Xfi, I had dropouts on the AES input on the digital filter settings other than TCM or FRM. Turns out, the other two aren't implemented yet, so I don't mind the dropouts so much on those.
 
My unit is also unwilling to lock to the coax output from a Sonos Connect, but works fine when the same output is run through my Genesis Lens and output via coax from there. Also had to change setting in MIDI Audio Settings before the USB from my Macbook worked.
 
Anyway, testing configurations continues. But initial sonic impressions are very positive.

Lachlan here. A month ago I posted a video that demonstrated issues with my Geek Pulse that were severe enough to damage a headphone, and which did in fact blow my Takstar Pro 80's. It was suggested by some people that it was irresponsible and premature to post the video without getting Light Harmonic's response, while some other people were glad to be alerted to a possible issue.
 
I'm here to give an update on exactly what has happened since then: nothing.
 

 
The unit is still sitting on my desk. It has been a month. My last contact was 9 days ago: I was told that the person my ticket was assigned to (Manny) was reassigned and couldn't respond to tickets. 
 
You would think that if there is a problem severe enough to destroy a pair of headphones, LH Labs would want to get the unit into their lab ASAP to see what is going on. Maybe so that they could prevent any other units from being shipped out with the same issue.
 
Instead it has been sitting on my desk for a month. In that time I have received 12 email updates about the various other crowdfunding campaigns and perks that LH is concurrently spruiking. Glad to see they have their priorities in order.
 
Yesterday, I got an email from someone who received their Geek Pulse, only to have it blow the right channel on their AKG K7XX. They were upset, but were uncomfortable about reporting the issue on a public forum.
 
I'd like to urge anyone who has had issues with their pulse to come forward. It's a matter of real urgency if there are units being shipped that can damage headphones.
 
To that end I've prepared an anonymous Google form to get actual numbers on how many Geek Pulse units have shipped and how many have had issues. This way we can get an accurate picture instead of conjecture. You can respond to the form here: http://goo.gl/forms/AR827KTu3t
 
Please share this form with other people who know have ordered a Geek Pulse so that we can get some more accurate numbers.

Welp, so much for that.

I wonder if they even knew which ticket was yours.

Apparently they did not know which ticket was mine. I do not want special treatment because I made a public Youtube video about it. I want to know how many Geek Pulses have shipped, and if there is a potential issue that causes it to blow headphones. When LH says they reached out, this means that Casey added me on Skype. We were not able to co-ordinate a Skype call due to timezone differences. This is the extent of the communication. There was no follow up.
 
I think a serious issue like this warrants a follow up, but again I did not continually complain about this issue because I wanted to see how this would be dealt with if I went through the normal support ticket system. Evidently, the result is that it gets passed to 3 different people and nothing gets done for a month.

Aagh reading that thread infuriates me. I didn't even post that thread but Manny seems pretty satisfied that it was a job well done on their end. I'll put it down to severe miscommunication but the lack of follow up is really galling. Meanwhile, the thread that I posted in to actually report the issue personally never got any official reply: http://lhlabs.com/force/techsupport-geekpulse/3356-geek-pulse-popping-led-flickering-issue

Yeah.....their support system is pretty mixed/lackluster from my experience too. I started a thread two months ago about a buzzing noise with the LPS4 when both the USB out and 12 V out are used at the same time and an official LH representative still hasn't replied in that thread despite others experiencing similar issues. I opened a ticket last month and the issue still hasn't been solved. Someone else had their unit exchanged and the problem still persisted. That same person had a Skype call with an LH representative about it and was told that they would look into the issue and an explanation would be given in about 1.5 weeks (about now actually).

I did have 1 really great support ticket interaction with Jody though and he replied to my inquiries within an hour, so that was awesome.

So either LHL got screwed by pcb board house big time or their QC somehow degraded tremendously.
I don't remember pulse had these many issues shipped last year.

I don't remember pulse had these many issues shipped last year.

 
And I'm not necessarily claiming that there *are* that many issues, though obviously blown headphones are a very serious issue even if isolated.
 
The form is to get some independent corroboration on LH's numbers, and to make it anonymous so some people who might be uncomfortable about reporting an issue might do so now.
