hm concerns are starting to come out with regards to the chassi's build quality...
Did I make a good choice opting for the V2+... :(

At around 320 dollars (shipping included) hope it is not as clumsily made as it sounds from a chassi point of view...

IMO it sounds great. SQ-wise this is not shit.

@ Ultrabike You can check DSD x1, x2, x4 and DXD with free files from 2L http://www.2l.no/hires/

All 2L tracks have been recorded with the Merging Pyramix system in 24/352.8 DXD and then converted to the various formats.

Will do later tonite. Thanks mate!

Larry Ho will love these graphs.
Hopefully my GOV2+Infinity arrives before the weekend!   headbang

balanced IEM cable and balanced 3.5mm adapter for HD800 sitting here ready to roll....

Please provide your impressions of balanced vs unbalanced.

Thats respectable performance for a device of its kind, wonder how it performs in standalone DAC testing.

Proly a very decent DAC on its own right, with quite a bit of data rate and format support.

So the sound is more or equal to the O2/ODAC with slightly less power, but the benefits of a portable?

No unique sound signature to differentiate itself?

I don't have an ODAC to compare. But I can say the Geek V2 pairs well with my HD600 and I get quite a bit of resolution out of it.

Thanks for your efforts. Looks like a compelling solution for the size/price.

If you are looking for something practical that just plugs to your laptop on the go w/o the need of a wall wart, it is a very good solution indeed. Not a lot of options out there in its class that offer balanced outputs, DSD/DXD and high rate PCM, class A amplification w half decent output power that still manage to fit in the palm of your hand.

Please provide your impressions of balanced vs unbalanced.


won't be able to do so with HD800 for a variety of reasons:

1.  GOV2+Infinity delayed a week due to 3D print case issue.
2.  the HD800 cable I have is balanced XLR, and I only have an adapter to 3.5 TRRS.   not single.

i could check out Balanced vs. not with my IEMs tho... more then!

I fucking thought so. When I mentioned I thought their 192khz tracks sounded worse, someone said those were the original recordings.


As always the original master file is the best and 2L works on DXD. I prefer an OMF even if 24/44.1 or 24/48 to an upsampled 24/192 or converted PCM>DSD. Even worst I see no reason in buying digitally mastered and recorded LPs. Very few actually record on DSD (Grimm has a nice ADC for x1 DSD), most would go for PCM (24/96 or 24/192) and then mess up with the market by selling just about every possible format..

2L is among those few that will sell you the original DXD and on a proper system those files are amazing. For serious DSD testing do try the native DSD files https://www.nativedsd.com/

Can I run it from my USB port with no wall wart? No.
I can run the ODAC and O2 with just a USB port without a wall wart. : p

You should then start a thread and get busy providing details about how to go about it :)

Folks around here perhaps have made it a slightly better product by giving it a better power supply (DIY stuff).

Hmmm... AFAIK the ODAC is USB powered and the O2 has (rechargeable) batteries so you can plug the lot in an USB port and have sound without needing external power.



Great set of measurements..
Thanks UB, was curious about it.

I do wonder about one thing though but think it can easily be explained though.
AFAIK there is a 'direct link' to LH so I will pose the question here as UB mentioned what is sortof a question mark for me.

The TPA6120 is a class AB amplifier.
It is mentioned that it is a class-A which could be possible by adding a current source from the output to the positive or negative rail forcing the TPA6120 opamp's output stage to work on output device only sinking into the current source.

As the output voltage isn't very high (in this case by a limited power supply voltage and the output current capabilities of the TPA are 0.7A/ch it would be easy to bias/load the outputs with say 0.2A so you can have the output in class-A even with 16 Ohm HP attached at max output voltage swing.

I simply wondered if that's how they set the TPA in class-A ?
Would generate a lot of heat though.

That's a good point. If the ODAC/O2 is operated through 9V batteries I guess you could go w/o the wall wart. Dunno if it would measure as well as w the wall wart though.

I'm also not sure how LH forced the TPA6120 into class A, but the Geek does get hot.
