I believe that the relevant point is that you should be able to turn off the Pulse and have it work properly when you turn it back on, While I have not really tried to listen critically for possible improvements in SQ after hours/days/weeks, I have experienced numerous difficulties when I...

  A delay from LHL?   Their delay in response will likely be blamed on a dock strike or production house issue.

  If your order was placed before the end of 2013, they should resolve this.  Many are in the same situation - expecting a mu metal shield (whether you can hear a difference is another issue), and through LHLabs' negligence, willful or due to incompetence, it is not delivered as promised.  ...

I will contact them about the missing shield. They have gotten away with so much BS already that I want to hold them to this.

True. My main point is that it should be there. Part of me thinks that i should hold them to their promises (although shipping back and forth is a hassle. Most of me says f#ckall, get a new DAC from a reliable and honest manufacturer.

    Looks like no mu metal on my Xfi. Initial order on 31 Oct 2013. Not sure if there is any noticeable difference in sound quality, but, still, What ?!

Can anyone confirm whether or not LHLabs is still in operation or has folded? I have another 6 months of warranty left and malfunctioning unit. No responses to communication. Of course i consider myself lucky/smart since no other products due.

Larry, Why is LPS better? Doesn't the external power solely charge the battery, and the device is powered by the battery during operation? With that said, mine is powered by an LHLabs LPS, as it had an open port anyway. I just want to know if (and, if so, why) it makes a difference to power...

  Of course they do fundamentally different things and are complementary, but if your question is which one makes the most improvement in sound quality, that may be difficult to assess across a wide range of systems. I installed mine about two weeks ago and have it powered from the 5V output on...

^ Not an ideal operational situation, but easier than sending back.

  Tried it several times in many differing power up / power down sequences. No luck.   Still no reply from the LHL people.

Thanks, mscott58, but I have old chassis and Mac based system, so this requires sending back to LHLabs. Fortunately U have a two year warranty and live not too distantly from their site.   Methinks this is the time to buy a new and reliably built DAC, and retire the Xfi once I get it repaired.

my Xfi seems to have lost volume control after restarting after I returned from a three week trip.   i use balanced out, nothing in the wiring has changed. I verified that the volume is under knob control. the display on the volume changes, just not the volume for balanced speaker out or...

I would like to discourage potential buyers of used LC's from overpaying for used ones, especially in light of the fact that a new run is seemingly on the horizon and that, with a little patience, the price of a used LC will be reasonable. In addition to to the British example of ~ 600 British...

  Do you truly believe that subcontractors have been the major source of all the delays?   It may be expedient for LHL to continually point to production plant problems, dock strikes, etc. These things seem to occur with regularity with them and offer convenient excuses for lack of proper...

So far on my Xfi/LPS I have only used USB for music with a REGEN just before the DAC. The TOSLINK is connected to the TV.   Thinking about trying a converter such as the MUTEC MC3 smartclock USB, but not clear how good the AES and SPDIF inputs are for my Xfi/LPS.    What are the experiences...

Maybe I am a dreamer, but I hesitated too long and missed out on the LC. So if any one has need to sell PM me.

I am amused at how Larry and the gang attempt to spin the further delays as a positive about their dedication on insisting on quality, particularly with the numerous faulty units of varying models that they have shipped. Just more BS and attempt to shift the perception of fault. What temerity...

  From Amazon web site five minutes ago regarding LHLabs Infinity:   "Only 9 left in stock, (more on the way)" "Get it before Christmas" "Want it Tuesday, Dec. 22? Order within 9 hours and choose One-day Shipping" "FREE Shipping"   What? Perhaps the Amazon review section would be a good...

Personally I have never dealt with a more irresponsible, disingenuous, and poorly run company than LHLabs, even though I have crowd-funded a few things before. If you set yourself up as a company of some audiophile engineering genius, please have the production chops to fulfill the promise or...

Wow. The temerity of those guys is astonishing, especially as their products are nothing special and the MSRP is way overpriced. I hope that commercial Darwinism plays its out for this lot.

  Cool. Let us know how (or if) it works and sounds.

  You mis-interpreted my Thanksgiving message. I'm not leaving Head-fi, just expressing thanks that I will have no further dealings with LHL including not going to the trouble of getting the intermittent and frequent issue with my Xfi repaired through their open-a-ticket, send-it-back routine...

Today I give thanks that I came to my senses over a year ago and stopped any further purchases, perks, upgrades, or investments in vaporware from LHLabs.    My Xfi has been returned to LHLabs once already and it has the SQ of DACs that I could purchase now for ~ $600-800 (I paid about $900 for...

For me sound quality is most important. The very slight pressure is absorbed in the hard connector. I used my Lightspeed 2G and Mapleshade Clearlink Plus, and the hard connector sounded noticeably better. There are other short USB cable (Aqvox for example) but I have not tried them yet.
