Hi guys, long time lurker first time poster here,
I am really interested in this new geekout and while looking for further info on the DAC ESS chip I just noticed that on the productor site the ES9018AQ2M is no more present but the ES9018k2m of geekout v1 is still listed... Have ESS discontinued their new DAC mobile flagship?? Any news on that side? Will LH labs act accordingly changing DAC chip?
Thanks

The V2 is still listed on the LHL page as having the AQ2M - http://marketplace.lhlabs.com/products/geek-out-v2-usb-dac-headphone-amplifier
 
As for the Sabre site and the AQ2M and where it shows up or doesn't that's a good question. 
 
Cheers

LH Labs website is so continuously out of date though that I'd hardly consider that proof of anything!

Ha! Great point.

AQ2M is listed as

Flagship Sabre Stereo DAC ​

in their taiwanese site: http://www.esstech.com.tw/products_DAC.htm

Hello Frederic.edinval,

This is Matt from technical support, I have received your support case and will be further assisting you with any questions you may have regarding your product.

I apologize for the delayed response.

Here are the calculations for Single Ended and Balanced outputs for the Geek Out V2+ in "High" gain.

Single Ended:

32ohms: 0.125w --> 125mw

50ohms: 0.08w --> 80mw

300ohms: 0.013w --> 13mw

Balanced:

32 ohms: 0.5w --> 500mw

50ohms: 0.32w --> 320mw

300ohms: 0.053 --> 53mw

Hope this helps!

Matt

So it s not that powerful unless you're balanced

Interesting, so the 1000mW into 16ohm is for the balanced output only. A little bit of obfuscation not stipulating that.

I was surprised how the AKG didn't sound all that loud single ended. Meaning I could hit max volume and not wince. Balanced would probably give more power. Quite sneaky of them lol

So it in balanced it has power rating similar to mojo.... Hmmm didn't realize micro idsd was such a strong amp

quite you say ? Hopefully i didn't buy this **** i would have been so disappointed

This whole story reminds me of that story I read in some Ephraim Kishon book where a shoemaker had a sign in his store window saying "We repair your shoes while you're waiting". He continues to say: "The repair took him 2 months. But I can't deny I was in fact *waiting*".
 
To me its really interesting how patient some people are... the constant ridiculous delays combined with those sneaky power specs, the constant "achievement reports" in best Neusprech would have scared me off had I researched before ordering. Really glad I cancelled this fiasco long ago. Paying 6 months in advance is not a deal. I mean come on...

I had ALWAYS assumed that the 'high' output figure (1000mW) was for balanced output into 16 ohms: ie with maximum 4v p-p, and 2v p-p for SE. This would give the power figures quoted: ie V^2/R. The greater the impedance of the phone, the lower the power, as normal.

Of course, this is peak output rather than rms.

 
I don't see anything sneaky about Ohms Law.

Does anybody know some handy USB-C to micro-B cable to use V2+ with new Android phones? Ebay or elsewhere.

That's the point: you had *assumed*. Others had assumed otherwise because their regular use case is SE. Another point: why is this peak of course? I for one, coming from pro-audio, am used to RMS / continuous power output stated... so I would not find it natural to assume any given value as peak instead of continuous (btw.: how is peak defined now? 10ms? 1ms? 0.01% THD? 0.1%? 1%?)
 
but to cut a long story short: to me output power is vastly overrated (everywhere, not just around head-fi). I don't use any planar magnetics that would really require some serious power. Besides that the difference is still not relevant between 500mW and 1W... those last 3dB are not my personal use case. Even my old HP-P1 with much less power drives most of my headphones quite well actually.
 
And no, there's nothing sneaky about Mr. Ohm himself... Sneaky is just stating numbers without context and boasting things like 'most powerful portable' or whatever they actually used to say. Reminds me of the old MHz/GHz discussions regarding processors... mostly irrelevant.
 
So I don't question that device having enough power to drive most headphones -- I'm sure it does that. What bothers me is numbers without context. I.e. the marketing.
