Is it still the same 1 W going balanced with the lps? Isn't supposed to be nore powerful? Are you using your he1000 this way. If that is the case mine will go up in the fs section ASAP. That is some bull crap. I thought the lps helps its power out put. When I opened up a ticket this is what I was told. Edit: actually the specs say its more powerful that way.


Eh?

Lol i made no sense. I just re read it.

I meant to ask... Isnt it more than 1 watt power output from the balanced headphone out. The specs day its more powerful balanced.
I know the lps just gives it clean power but I was curious if his sentiments of it not powering his he1000 sufficiently was even with the lps in place(just eliminating all possible contributing factors)

I don't believe LPS increases the power to the unit (but I really am no electronics expert), think it provides cleaner power, as noted, the output from the amp of the unit shouldn't be changed. I use a MicroZOTL2 for my HE-1000, seems to be enough power to drive it well (others using it also find the same), rated at 1W. Some have used LPS with the ZOTL, say it improves sound quality, but only by a very small amount, didn't get the sense that it increases power any. But, as I said, what to I know. (I do remember that WATTS and not WATTS, in other words, the watt measurement isn't the only determining factor in what it can drive, current can differ, tube watts are said to be different than solid state, etc...).

I have a Pulse Infinity driving HE1000s and HD800s. For the HE1000 using the balanced output I usually use -dB in the 30's The HD800 fare about the same with about 10 less -db than the HE1000 if memory serves right. I power my Infinity through an LPS4.
 
EDIT: on high gain setting

the xlr 4 pin port has double the voltage swing of the 1/4" headphone out.. it doubles it to 14Vrms.  not sure how current is affected.. might still be 3 watts at 16 ohms?  It should definitely be enough for most headphones on high gain
edit:  I use my he-560 with geek out v2 on 100mw setting and it's loud enough at 70% volume for any non classical music

A Japanese backer posted some interesting stuff, including inside shots and power consumption for both Infinity and vanilla Pulse.


Solid find!

They said "Batch two will focus on international orders. We’ll provide more info regarding a shipping date in a couple days." on Indiegogo around two weeks ago. I am one of the early backers (October, 2013) and have nothing from LH Labs so far. Not surprised that they fail to keep their word again.

My understanding was that they shuffled international orders that would have gone out in Batch 1 to Batch 2.  Which I think makes a lot of sense.  It gives them a chance to catch and fix issues locally w/o excessive shipping.  
 
Sure everything should have gone out sooner... but the people screaming about not being in the first batch, would have been screaming about the excessive international shipping, if there were an issue with the product.
 
At any rate, I hope that they get these batches out and then we can stop complaining and start listening to good music.

Sending my Pulse X back today for RMA. I've had a right channel signal lock issue since I first got it. All inputs have no sound coming from the right channel when the sample rate changes. Sometimes there will be a static sound coming from the right channel. I have to select another input, then back to the input I want to use, then sometimes turn the volume up a few clicks in order for the right channel to begin playing. I'm hopeful it will arrive back soon and in perfect working order.

Sorry to hear that dude... Hopefully the turn around is not long

The comment earlier about the FEMTO clocks need to be at the right temperature for the best sound definitely makes sense. I have been shutting my Infinity off nightly. When I turn it back on the next day, everything seems very harsh. Give it roughly 1-2 hours and the sound signature returns.

I see why the Wave with FEMTO clocks is a challenge given the difference in sound between cold and warmed up.

I believe they recommend not shutting them off.

With just the Infinity connected, the LPS4 seemed warmer than I would expect so I decided to shut it off at the end of the night.


Wow, my LPS4 stay cool, not even slightly warm, when powering the Infinity and Uptone Audio Regen.
