Yes I have the Mojo, and the big brother from nano iDSD the micro iDSD (and micro CAN, and others lol) too. Compared them here: http://www.head-fi.org/t/789009/chord-mojo-vs-ifi-micro-idsd-vs-m9xx-optional-vs-audeze-deckard-lcd-3-or-sony-xba-z5#post_12123174

Great review but, so which one is more of your go to. Im trying to find something to go with my DX90 and its either something like this or the Mojo. I see you prefer the Mojo for IEMs and iFi for full size but what sound are you liking more?

Sound impressions are too subjective to tell, I could now start with a long 'flower speech' about both devices, but this would not help any one. Since both devices delivers really outstanding high SQ, I would if you want to pick at the end only ONE device, choose the right for you and your gear - like think about: form factor, battery life, inputs, outputs, features, options, and and and.

Hey guys,
 
I just ordered the DT880, Fidelio X2 and the HD650. Do you guys think the ifi nano amp will be enough to power these headphones for a comparision or should i look into buying a headphone amp.

It will run them, but I needed more to make my 400i's come alive.
 
iCAN SE is calling your name. Or go Micro iDSD.

I was able to obtain a iFi nano, is there any easy way to hook this up to a DX90?

There is no easy way - in fact, there is no way to hook it up to DX90.

Do any of the ifi line connect easily to the DX90

Yes, the micro iDSD can take DX90's coax-out.

Can the iFi products be used as an amp only with rca inputs? is there any reasonably priced portable dac/amp that can?

Hi,
 
This is how A&K customers take the next level up. Should be the same for DX90.

The DX90 has coaxial out instead of optical toslink out like the A&K, a different cable is needed.
 
This is how to connect your DX90 or DX50 with the micro iDSD:
 

 
On top is my custom made Mini to RCA coaxial cable, on bottom the default iBasso Mini to RCA cable which is a part of DX90 / DX50 package, no need to buy a addtional cable, only if you want like me a smaller cable. The small adapter you can ignore, it's for a different device needed.

Hey guys.
 
When going from the nano idsd to receiver to speakers, is there any difference between using the headphone jack output and rca output? Or are they exactly the same, just making sure to max the volume knob on the nano?

Same and yes.

Hi everyone.
 
I really like this device, but I've had some issues with my iDSD nano.  With 2 different units.
 
Often, one of my RCA channels drop out.  Usually it's the left channel.  Sometimes the right.
 
It usually happens immediately when I unplug the headphones.  But sometimes, after 15 minutes or so, the audio will drop.
 
Usually plugging and unplugging the headphones fixes the issues.  But sometimes it doesn't.  Sometimes, unplugging the RCA cable and plugging it back in helps.  Sometimes partially inserting the headphone jack helps.  Sometimes unplugging the USB connector helps.
 
The causes and fixes vary, so it's a hard issue to pin down.
 
I originally started using my iDSD nano around the beginning of January 2015.  I don't remember when I first started having issues, but I contacted tech support around August 2015.  Ifi tech support suggestion repeatedly inserting the headphones, but that wasn't a permanent fix.  Eventually I was forwarded to the retailer and I received a replacement unit.  I received the new unit at the beginning of September 2015.
 
At first the new unit worked great.  But, over time, I've noticed the issue happening again.
 
Since I've already replaced one unit and have what seems like the same issue twice, I'm wondering if there's an issue with my setup, or something that I'm doing.  It doesn't happen often enough that I'd consider talking to tech support again, but it is starting to bother me.
 
I have the iDSD nano, with the latest firmware (I updated the firmware to the 5.0A).  I'm connected to my PC (Win7 x64) via USB 3.0.
 
The RCA cables are connected to a pair of powered monitors, the Emotiva Airmotiv 4S (http://emotiva.com/products/powered-monitors/speakers/airmotiv-4s)
 
The headphones I use are the Sony MDR-7506 (https://pro.sony.com/bbsc/ssr/product-MDR7506/)
 
I switch between my headphones and speakers often.  At least twice a day.  My volume dial usually doesn't go past the halfway point.
 
With my first iDSD nano I did test on other speakers and the issue still occurred.  I haven't test with other speakers with the new unit.
 
I'd appreciate any thoughts or help.  Thanks.
