Whoa!!  This is around 20 post/day.  You guys better start giving stuff... ~

20 posts per day? Could you please share your math with us? We lack 44 posts to hit the number, at least that's what our profile says... :wink_face:  

Oh, I was referring to this thread, which has 1724 posts.  (2000 - 1724) / (31 - 18) = 21.2.

Nice save! We believe you

Tip off the hat, that's a fab explanation

I've been listening to my iDSD Nano for a couple of years now. Stellar sound, especially with DSD256 through to my SET Tube Amp.
 
The Nano benefits from not being directly connected to the computer's GND and power - made a big difference in my setup (YMMV because of ground loops or what not). Much less glare, and more micro-details.
 
iFi recommended I get an iDefender 3.0 so that I can do the ground isolation safely as well as inject clean power.
 
I did do a little additional experiment injecting non-computer power, but also an external SMPS by using an iPhone charger.
 
And here again, much better sound (in terms of less glare and detail) than when using a normal USB cable like the default furnished one or any low-cost off-the-shelf one.
 
It's quite incredible we can still get additional performance for this little DAC with great capabilities.
 
I have a couple of questions for further building the power-side of my setup with the Nano. In particular I am thinking of having a battery to feed it the main 5V.
 
I would probably build upon a couple of 18650AF Li-ion batteries.
 
One of the question that comes up: should I use a regulator with the batteries down to some voltage 5.x or so before inputting this to the Nano, or does the Nano already have internal regulators that make this unnecessary?
 
The reason I am thinking of using these batteries is that I already have them and have seen people saying they use batteries with trickle-charging to power their DAC (not necessarily the Nano itself).
 
If there's anything I should take particular care of, do let me know.
 
Thanks a lot.

I'm also using iDSD nano, no luck like many of you. I do like the sound quality, but the build quality and poor customer support has stopped me from enjoying the music. From the search online, it seems a common issue with iDSD nano headphone jack interfere with RCA output, makes 1 channel of my RCA gone on and off randomly. Repaired once during warranty period did NOT fix the issue, and now over warranty period, they try to charge me for a problem they previous couldn't fix and from the conversation with ifi tech support, they don't seems to know the cause of problem but willing to take my money for another repair. I've lost my trust in this brand, they try to package and sell like an Apple product, but don't have the quality or support to back it up.

FWIW, I solved the RCA output on mine using Hosa D5S-6 CAIG DeoxIT one the contacts.

Haven't had that issue myself as I don't use it as a headphone DAC, but I had stellar support from both iFi and Avatar Acoustics from which I purchased the DAC.

I've never used that before, so do I open the chase and spray around headphone jack connecting area? What I do to temporary fix the problem is poke my finger to headphone jack, move around till both channel come up. :/

I did not opened it.  I just sprayed the connectors and plugged them in.  This was two months ago and I have not had problems since.  (Fingers crossed...

thanks for the tip, looks like I might have to invest a Hosa D5S-6 CAIG DeoxIT....

iDSD BL is #1 in Japan

Uncork the Johnnie Walker Black Label!
 
 
Breaking 'Black Label' news from iFi Audio HQ!  iFi Audio is proud to announce that the micro iDSD Black Label is the number 1 seller in Japan this Christmas! Yes, that's right  - No. 1! 
 
 
Check it out here: http://kakaku.com/kaden/headphone-amp/ranking_2073/spec=101-2/
 
 
 
The micro iDSD Black Label proves that black is indeed beautiful when it comes to headphone amplifiers. The new black/burnt orange colour scheme in combo with its awesome design features are a force to be reckoned with across the globe.

Congrats.
 
This thread is about the Nano though.
 
I've settled on making the output voltage of my PSU 5.25 like the max USB standard voltage. I figure that any internal regulators in the Nano will work with that.
 
Can we know the max current draw for the Nano so that it can both charge the internal battery and play?

Nano iDSD is compatible with USB 3.1 (Type A) ?

No, iDSD nano is compatible with a USB 3.1 B-Type plug as it is a downstream device.
 
Downstream devices must be fitted with either a USB-B socket (as is the case with iDSD nano or a USB printer), an A-type plug (like the iDSD micro or a USB memory stick) or C-type socket.
 
As long as the correct cable is used however, the iDSD nano will work fine with USB 2.0, 3.0 and 3.1 equipped sources (computers etc.).

Sure. USB 2.0 standard 500mA (+/-5%).
