  i have a few dacs...dragonfly red, ifi micro idsd, chord mojo.
just wondering how the v2+ infinity compares quality/sq wise to the mojo and micro.
 
i'm looking to step up the game for sq in a dac...ideally looking for one that can work
as a tt, too fo cans/ies and powered speakers...also considering the..hugo2 even ...but $$$
 
one thing i do like about the v2+ infinity is it's slim, lightweight profile
vs the bulkier mojo.


I have the V2+ Infinity and the Mojo.  To me the Mojo has a warmer, more musical sound.  The GO does offer some filters (I always run the green one), but sounds more crisp and digital.  The balanced output of the GO is better than the SE.  The GO also doesn't have a volume control, which has become more annoying to me over time.
 
The thinner form factor is nice, but it is also longer.  The only input is USB - which it had a coax in too.

I took a look to this video so much often but i think it just The light... if you wait, you will see the lines diferently!!!!

The video was posted in late 2015, so there is no way that he had the latest version. Around 4:40, he even says 3d printed plastic. At around 5:00, you can see those lines. And I think the 3d printed plastic reflects a lot more light than the molded ones. 

Hi all. I came to the thread again to get a photo that I took and I stumbled upon this post.

Indeed, this is an outdated version of the unit. The aluminum faceplates on this version were more of a glossy-matte finish that showed fingerprints more, no silk-screening on it, and the frame and buttons were 3D-printed (or at least felt and looked like it).

The current version is much, much nicer.
Here's my review video for it.

Yeah I don't care in any case ^-^, maybe in france the people not so much interessed in this device and they want to make sales to get rid of them in their storage :D ?

Excellent review :D I can definitely agree on the filter part. After a lot of going back and forth between the filters with different songs over and over again, the difference is definitely somewhat audible. The FRM seems adds another layer of something which I'm not sure what it is. It makes the whole sound smoother overall, but sounds somewhat muffled compared to TCM filter. Due to this layer being added, imaging and soundstage is also affected, slightly making it harder to position and just slightly more congested sounding. The bass can also get a little bloomy (lacking tightness and control) and the treble can sound splashy at times. It works very well with specific songs and sounds beautifully airy while sounding natural, reminds me of how mojo sounds. However, with the rest of songs, treble is splashy and sounds too bassy without control. With the TCM filter, none of this is presented, so it sounds cleaner and controlled to me with more forward vocals. The downside of this filter is that sometimes it's not as engaging as the FRM filter and can get too analytical with sharp sounding treble and lean sounding bass with certain songs. I'd love something in between.
 
Which filter you favor depends on the IEMs or headphones in use, but the basic characteristics probably won't change. It's interesting that I highly favored the FRM filter for a few weeks, but then once I got used to the cleaner sound of the TCM filter, I just can't go back.

Thanks, seems working fine with Shanling M1 which has USB audio output and since the GOV2+ has only software volume control this is very important to have a DAP with good USB audio implementation which handles the device properly.
 

 
Balanced 3.5mm TRRS cables on the way too.

I think you will ike the balanced out!
Very cool with the M1. I may have to try this - almost had a dream setup with a Sony A10 walkman into the V2+ but for some reason the A10 cannnot control volume OTG! (though it also only has 30 steps control so maybe it wouldn't have worked out that well anyway).

Lol..."LHL has a secret" (http://lhlabs.com/go2pro/)
 
Group buy has already started...hurry up all you LHL fan boys :wink:
 

 
Edit: so what happens if the threshold of 100 units won´t be reached? No sale? Or at the full price?
Just thinking....
 
....and when will the "Group buy period" end? And will the devices shipped immediately after the end of the Group buy period?
 
So still the same uncertainty as always....nothing has changed with their communication style.

30 steps only? That's sad you can't use it, I like the Sony A series, the Shanling M1 offers 100 single steps volume control, this suits very well with the 64bit digital volume control from the ESS DAC, works well with sensitive IEMs too.
 
But is it "normal" that the power LED is permanently off? Very strange because the first tests I have seen the blue LED alwas on switching ON, now it keeps LED off, all other LEDs working fine (Gain, Samling, Filter), the device itself works also very great, very odd!
 
Only a bad placement of the USB input, I can't really reach the 3.5mm TRRS port with this postion, I need to find other short USB OTG cable...
