I made a little survey for Geek Wave backers if anybody is interested.

Nice to see the V2 chassis being delivered... 
 
... meanwhile, I'm still waiting for my V1 chassis pulse Xfi... 
 
(which was supposed to be 100% delivered by the end of Sept, 2015).

Yes Mike, power both the Regen and the Pulse off the LPS4.  My wife is going to feel neglected tonight!

 
Similar setup here as well. I often wonder if the benefits of the split vs non-split editions of the 10G cable become diminished with the Regen completely blocking the power leg.

Or is it High Hopes from the double live album Pulse?

You got the album right but the track was: Shine on You Crazy Diamond!

Got the infinity.
The bass is weak out of the box but definitely not severely lacking.
Overall much better looking than 1.0 chassis but the side screws are protruding and not even, so I take off the cover then try to re-tighten the screws, and, the cover won't fit agin, so I have to loose the screws put on the cover then tighten the screws again. I don't know if this tolerance is OK in LHlabs's QC book but if I am paying more than $1K for this I would return it and ask for refund.

I don't even plug the power leg of the 10G in.  The Pulse doesn't use it and the Regen bypasses it so there's no point.  Mine works just fine without it.  If you don't have the split the power is active in the cable.  Probably doesn't make any difference but with the white split, with power leg not plugged in, less EMI/RFI.

Do you ever experience your Pulse not appearing as a system device after your computer comes back from standby, until you perform a power cycle?

With the Regen = yes.

Without the Regen = no.

One of the trade offs that I have to power cycle the Pulse at times, but not a huge deal IME.

Cheers

Got mine too.

I'll check to see what my screws are like.

On the whole, it physically feels SO much better than the first chassis. I'm so glad that I waited.

I need to bring my real headphones to work and try it out. Probably need to just let it run for a while.

Haven't powered it off or let it go into standby yet.  Left it on since I got the Pulse.  Breaking it in!

Same for me, but it's quite annoying--why can't it just 'work'...

Love USPS (by the way, Little Rock, AR is 3 hours away from Fayetteville, AR)

Got the Pulse infinity today.
 
Hooked it up with Jay's audio LPS with 2G cable,
data end to computer and power end to an Anker USB portable battery charger to emulate plugged in usb power.
(the charger it self seem to shuts down after the initial hand shake, due to having no active load. )
 
, set everything up on windows, play via JRiver through ASIO, DSD bit perfect output, etc. , after a bit fiddling with settings, everything was good to go.
 
The initial impression? Not bad, not bad at all.
 
The DAC managed to squeeze some subtle detail out of some sound tracks compare to Buffalo II without feeling too harsh or distracted.
 
The instrument separation is slightly better as well.
 
The over all tone is pretty much on par between the Buffalo II and Pulse Infinity though.
 
The only gripe is that the lower drum/base doesn't seem to pack as much punch as the Buffalo, hopefully this will be fixed after few hundred hours of burn in.
 
 
Also... I am running balanced HD800, low gain.. at -24 dB for a normal listening session... this seem to be quiet a bit of attenuation for low gain settings... anyone else is having similar experience?

same here, balanced HD800.

Same here. Plain X, balanced HD800, low gain, -24db thereabouts.
