LH Labs Geek Out v2 Discussion Thread

Jul 3, 2015 at 1:44 AM Post #346 of 1,391
got the v2 and just plugged in in after the necessary driver upgrade. first impression, it makes the 450 sound bright and thin by comparison. A much better synergy with the he-560. I can imagine it is for the Q701 as well. A much more relaxed presentation with a big solid bass. oddly I don't think its any louder than the 450 was with the 560. But then again its been on for 15 minutes. after burn in I may notice the volume a little more. could be that the loudest part of the signature before was the upper mids and that is not the case here. much more balanced with a tilt towards the warm yet some how at least as detailed. its a big improvement. I can hardly wait to hear it with the darker ZMF vibro. A desire which is about to come to fruition as the wife will not tolerate the 560s generous volume to the environment. So in short, better bass quality and quality a less aggressive high end while retaining the detail . Im also getting a greater sense of depth of soundstage and realism of tone. so far this thing is a winner.

+1. It seems like LH may be making progress in meeting deadlines, and genuinely positive reviews from real users are coming in about the performance of the v2.
 
(notwithstanding whether or not their upper management has made any progress with customer service skills and ability to admit fault). And yes I believe these reviews are from real users

day 2 a change of music has revealed beautiful texture from the 560 and v2 combo. more space, greater dynamics and even more authority on the bass. still, the sound is very balanced in this set up. Timbre and realism are astonishing for its footprint. one of these days i'll get a balanced cable to utilize this gear to its maximum. for now its very impressive as a portable SE solution. Most of my listening takes place on the porch with a laptop so a portable of this caliber is greatly appreciated.,

Larry I have a question about the topology of the circuit.  I was looking at the diagram you posted on the wave campaign and it seems that when you say balance you are talking about the headphone output.  I think the diagram shows that the wave (any thats not a xd) has a single ended analog signal (I/V + LPF)  that is then split to balance signal for the headphone output.  I was wondering if this is true for the v2 (I read somewhere that they have similar analog stages).  You said (in a youtube video) that you are shorting the neg signal to the single ended output of the v2, why not just bypass the signal splitter? 
 
If so for those using this as a dac for an external amp do you recommend using the single ended output (shorted neg from split signal) or balance output (split single ended dac output)?

Question: does the original GO work with the 2.29 driver? I read in the manual v2 needed the new driver. I don't want to damage the 450.

I'm using my go450 with the new driver, works the same as before.  windows 8.1
edit:  think I had to unplug, reboot, replug once after install.. can't remember though

Hmm that's really good to hear! I wonder how it compares to the Ifi micro iDsd/he-560 pairing. I have a V2+ coming but I wonder if the difference between them are more than just the battery.

I didn't want to wait the extra time for the V2+. I didn't know they were gonna be so fast with it. Besides all I wanted was a more powerful amp for the he-560 and Vibro to use with a pc on my porch. the battery pack and expanded portability/versatility is not necessary for my uses. I don't really listen that closely around town. It just isn't smart. Times we live in. I don't know about the ifi. this town doesn't go far beyond the Beats. No community for hifi to speak of. Butt load of live music though.

Speaking as a tourist, I thought New Orleans live music one of its main attractions! With a wide selection, too.
I'm a v2+ guy, so it was with some interest, that I read the application notes for the Op amps in the V2. http://www.ti.com/lit/ds/symlink/tpa6120a2.pdf  I think the battery will help to deliver higher skew rates, perhaps more attacking bass.
 
There's some indication that the op amps might drive loads down to 8-16 ohms, so I'd be interested to know if they would drive standard speakers at low volumes, eg at the 1w level - desktop monitors perhaps.

Live Music is a lot of fun down here. But headphone people don't seem to share much if they are here. A producer here once told me " a little secret , use bad speakers for your mix and your final mix will sound awesome" I just stared incredulously. That dudes mixes sucked.
I haven't experimented with either geek product. My home stereo is fine like it is. Quad stuff. Not the els but I like it.

I think they're getting better even though updates still come in drips and drabs. I opened a ticket to change my shipping address and Gina took care of it within 24 hours - she was a good hire for LH. And yes, the feedback on the V2 has been stellar, so I'm very optimistic about how the Wave will sound.

I don't think this has been discussed before: can anyone tell me about grounding or earthing on the V2 and V2+ ? I'm thinking about 2 things mainly: is the USB input ground used as the main ground point? If I'm using an XLR4 connector (which has 4 signal wires and a screen connection) to my balanced headphones, where does the cable screen actually go to - the TRRS connector is only 4-way, not 5? Or doesn't it matter because the levels are relatively high on the output side?
