mini plug to rca adapter by Audioquest $12.70 in Amazon

Has anyone been using this a pure DAC and connecting them to a dedicated headphone amplifier? Do you think the amp section of the Geek would better the Cypher Labs Duet? Are there any negatives such as loss of resolution by connecting them to external amplifier?

I run a Geek 1000 directly into to a Pass @ -0dB and it works great! ;)

I'm using my Geek Out 450 as a DAC connected to a Project Ember and it sounds amazing. I don't know if the Duet is better or worse than the Geek Out's amp but if there's any loss in resolution, I sure can't tell.

Someone previously mentioned using the Geek Out with an iPad, I believe. I love my GO 1K as far as sound goes I really want to free myself from being tied to my PC (I know the Wave will do that, but seems it will be a year until we see that, assuming things are on schedule). Any info on doing this? I assume you need the camera option to output files from the iPad. Thanks

That might have been me, and the set-up was more proof of concept than an actual implementation.

It won't liberate you much, lots of parts to carry, you'd need a bag to schlep it all:

GO1000 mobile iOS, different exposure.

Additionally, the GO1000 isn't as well suited to this as the 450 would be, the power requirement/consumption is too high.

I also couldn't get the Onkyo HF app to work with this configuration, so hi-rez files wouldn't play that way, but the stock Music app did play up to 24/96 via iTunes Home Sharing.

Some of the bulk could be trimmed back if using a shorter split USB cable, and a smaller USB hub.

Much more liberating is the Resonessence Labs Herus, tiny form factor and no need for additional battery power or hubs/cables etc.. and it does work with the Onkyo HF app.

Thanks for the post...looks like I have to wait here at my desktop (which I'm doing this minute-nice sounding Hi-Rez Ry Cooder live from HDtracks, through Shure 1540,,,guess I'll survive smily_headphones1.gif

I run it to a G103 and in to my HD800 - no complaints.

I have triied it with my Headstage Arrow 4T...and the amp of GO1000 beats it convincingly.

post #566 of 912

I have a rooted android galaxy S4 (i9505 with 4.4.2), also installed are UAPP and UARP.

Recently I purchased the GeekOut DAC (450mw), which works fine with my windows PC's USB ports.

 

I did discover that when connecting the Geek DAC to my S4, directly via an OTG cable, the earphones (tested several) get extremly warm to the point of endangaring them. Using a Y split OTG cable and feeding the Geek with a 5 volt external battery, also heats the earphones.

 

Today I had purchased a Self Powered USB HUB which is fed via a wall connected power source. Connecting the S4 to the HUB's input port and the Geek DAC to another of the HUB's service ports, seems to better things; but the earphones are still getting warm (not as before).

 

When using a windows PC source (directly or via the USB HUB) the earphones stay cold. The cause for the heating seems to be the S4, the OTG cable, or both.

 

I did try several OTG cables, which works well with other DACs I have. Also the S4 works normaly with my FiiO E18 DAC as well as with my (battery-less) HiFiMeDIY android DAC with no heating and with clear sound.

 

 

Another standing issue is the fact that the GeekOut DAC does not support yet the Galaxy S4 (hope this will be addressed by an expected Light Harmonic Labs' firmaware update to the Geek).

 

Please advice

A simplified version involves only a powered USB hub, i.e. you do need AC power.

 

At home that isn't a problem, but you can't take AC power on the road of course, though you might have it once reaching a destination.

 

With a powered USB hub and the CCK, I still have a problem with the Onkyo HF app and hi-rez tracks, however the CanOpener app has no such difficulty and plays back 24/192 no problem.

 

So if untethered from the computer can mean still tethered to AC power via a USB hub, then you are in business with the iPad and GO1000 so long as you have the CCK.

 

This assumes the powered USB hub isn't sharing its power with all kinds of other devices, I've only tested this as working with the GO1000 being the sole device connected to the hub.

Thanks, have to give it a try, not really looking to take it out for walks, but would love to be able to listen in bed. I have a powered hum, though it has other things connected, but they're not too hard/expensive to get.

Here is what it looks like, a bit tidier than the battery powered set-up.

 

iPad2 - CanOpener app - CCK - ADL Formula2 USB - Ultra USB powered hub - LH Labs GO1000

 

This sounds better than the battery too, suggesting that particular battery I used has a cheap/noisy 3 pin regulator, or some other very bad for audio parts.

 

I guess it could also be that the generic y-split USB cable I used for the battery arrangement sucks.

GeekOut (450) does not work with rooted galaxy S4

 

Managed to obtain both dmesg and logcat txt files. recording both E18 and Geek connections.

 

 

at first I connected the FiiO E18 DAC, activated UAPP - success; then I connected the Geek Out, activated UAPP - failed to initialize USB device

 

I have the files (for some reason I cannot attach it here)

 

Can someone advice?

 

Thanks
