I gave up keeping up a year or so ago, too many products coming out now.

So far, non-mobile to me is suprieror sonically.  I've tried the LO of DX90 which contain the mobile version.

Did you get a chance to listen to a Geek Wave prototype/pre-production model?  I'm hoping this is what you are referring to as I just ordered the XD128, and it would help to reassure my purchase.

 

Thanks.

Dave.

 

 

I'm referring to their Geek Out USB DAC/Amp: https://www.kickstarter.com/projects/gavn8r/geek-a-new-usb-awesomifier-for-headphones/

 

 

It's simply great, and consistently sounds better than everything I've tried in the DAP realm.

WOW eke...this is interesting..

 

Can you tell me more about your comparisons of the Geek Out with other world leading DAPs like the HM901, AK240, DX100?

Which Geek Out did you listen to?

I'm referring to the Geek 450. I don't need more power than that. I listened to the HM-901, X5, ZX1, Studio V 3rd Anv, and compared them in this thread.

The conclusion of the thread was that none of them presented a single (sonic) reason for me to leave my current devices. The Geek was a completely different story. I had real "WOW" moments with it, which was a first for me in my long desktop and audio setup history. Go check out the threads and see what everyone is comparing them to.

Thanks Eke..imma go there and sub...

 

Hmmm...might as well get the Geekout 450 and try...Cheers buddy

Thread Starter 

I'm thinking actually of getting the Geek Out 450 and selling my GO1000 so I can use it with my MacBook Air on planes without so much power use as the 1000 has.

 

Edit: I can't wait for the firmware update for the Calyx M and am going to plug it in as a DAC for now. That may give it a slight disadvantage as DACs that can read from an internal SD card generally seem to have better performance, not having to deal with RF noise and jitter from USB.  

 

First up was Amber Rubarth through my UERMs and the HD-800s vs. the AK240 (balanced). Now I have a 3.5mm to AK240 TRRS adaptor I don't have to change the cable around, just move the plug from one DAP to the other, making switching fast. 

 

Starting with the UERMs and the Calyx from my iMac, the sound quality was very good, but a little un-involving and flat. This reminded me of my Calyx DAC 24/192 which had something of a similar issue. To reduce any negatives as much as possible I switched to using my MacBook Air and the same Oyaide d+ Neo USB cable and adaptor that I felt improved the AK240 in DAC mode (versus a generic micro USB cable from my iMac). This change improved things and the dynamics of Amber's voice were more present and "involving" -- that is, the feeling of the music was more present and made me more want to listen.

 

With the HD-800s, the Calyx M surprises with a pleasingly wide soundstage that I feel competes with the AK240. I still feel the AK240 delivers the subtlety and delicacy of the notes a little better, but surprisingly it wasn't to as much of a degree as I had expected. After the AK240, the Calyx M feels a bit loose in the way it delivers lower notes to the HD-800s and the sound is a tiny bit courser. If the performance from an SD card is similar to how I have the Calyx set up then I can imagine someone comparing both DAPs with their favourite music and not feeling any benefit from the AK240.

 

NOTE AGAIN: This is a slightly unrealistic comparison because I'm using the Calyx in DAC mode and not with an SD card.

 

The next test was Harry Manx - Mantras for Madmen, which is a bright, sibilant album. The Calyx M was more irritating to listen to this with than the AK240.

 

Last up was Just a Little Lovin' from Shelby Lynne (not literally though :D). From the AK240 Shelby's voice was a little more distinct and separate from the other instruments and the micro detail more apparent with my UERMs. The Calyx was a touch more course.

 

I'll re-run this comparison after the firmware update once I can use SD or microSD cards as the Calyx M seems to be a bit more sensitive to USB input quality than the AK240 was.

Thanks Amos.  What are the differences of DAC mode and sourcing from SD card?  My guess is that when connect to usb to a computer, the DAP's electronics are getting more current, so that can benefit the sound as a whole as I've experienced this with ODAC.  When connected to my desktop, it sounds fantastic, then when I connect to my smartphone, not so because my smartphone probably limits the current to the ODAC.

 

I don't understand why you would go with the GO450. Do you need an external power source for the 1000?  What are the differences between the two models?

Thanks eke2k6,

 

Well, I'm hoping for big things then from their XD128. If they can make a USB dac/amp sound as good as what you and others have said, I am hoping they can do the same or even better with their TOTL DAP.

 I'm also hoping that Currawong will add this to his DAP off once it is released:)

@currawong Were you able to drive the GO1000 using a MacBook Air 11" on battery power? I've been looking for an answer to this for some time. Thanks

Anybody has compared the HDP R10 or the DX100 with the HM-901(with iem card of course)?  I'm curious what the differences are.  After all these comparisons, I feel that the non-mobile version of the ES9018 is the superior sonically.  
Have you compared the DX 100 and the hdp r10? Is there ANY difference between the two? I'm about to buy the hdp r10.

I haven't, but I always thought the hdp r10 is the japanese DX100 and anybody correct me if I'm wrong.

Some changes but design-wise mostly the same. Differences include :-

 

- OPA627 OpAmps

- uses a different battery 4.8V instead of 8.4V (and double the mAh instead of 1/2 for the latter...well double & 1/2 depending on which is the reference base, you get what I mean)

- OS is the same but the skin & player are different. HDP-R10 supports DSD->PCM conversion realtime, whereas DX100 has no DSD support whatever.

Note to self.  Read the front pages of the threads.

 

Looks like I've done a blind test to myself without being aware of it.  I guess I like the OPA627 OpAmps.  :D  Not sure why the original had double the voltage, but that can have benefits for big cans.

Only a guess, but in the GO1000, the 1000 stands for 1000mA?  or 1A?  I don't know any computers that can output that much through the usb.  I thought usb 2.0 was 500mA, and usb 3.0 more but still less than 1000mA.

Hi, I was referring to your post #458 where you said you were going to sell your Geek Out 1000 (which is what I have too) to get a Geek Out 450 to use with your Macbook Air. I wanted to know whether you were able to use the GO1000 with your Macbook Air without the AC plugged in and whether the Air was the 11" or 13" model. Thanks.
