so it will have 3d on of, xbass on off.
1 question if i use with 30-300ohm headphone do i still need ican?
or i can simply just use micro dsd

  Designer's Diary (1)
 
Hi all. It's been a tough few weeks, feasibility studies, trying to fit everything, like trying to pour two pints of Guinness into a single pint glass. 

 
It's 23.07 GMT and we've just tucked into a KFC party bucket. While we aren't having a party, we're having a ball pushing ahead with the micro iDSD.
 
Here is pretty much the mechanical design, confirmed and in part with models built to confirm things fit. Much of the design matches what Roamling showed in the first few days, colour us impressed, we could not do much better.
 
Starting with the front, this will mostly resemble the iCan nano in layout, with the 3D Holographic sound and X-Bass switches.
 

 
The HP Jack will be 6.3mm. What you can only see on the next picture is that the Filter switch is a slider switch on the left hand side surface which will fit flush.
 

On the back you see leftmost the SPDIF input/output. This will be very interesting, more another time.
 
The two RCA line outputs are in the middle, then the USB input. We have built a mock-up and tested that even with modestly fat "high end" RCA connectors that just manages to fit. 
 
So, externally at least we can deliver a lot of what you all have asked for. More to come...
 
 
Ciao,
 
Thorsten

 
This is amazing! I cant believe you took my design suggestion and and went all the way to town to test the design and put in so much effort to make it happen. I am certainly very happy the way the design turned out and it looks very clean. The filter switch on the side is a brilliant idea.
 
Keep it coming! Cant wait to see more features, this whole project really rocks...

Putting in the 6.3mm jack that is good. Sounds like you have a trick up on your sleeve regarding the SPDIF input/output.

I did not even notice the digital RCA is "in" AND "out", things are certainly getting interesting here

 

[BillsonChang007]

Indeed!!! Will there be a gain switch for the iDSD micro as suggested or the amp doesn't really need one? @.@

 

[iFi audio]

Excellent design! We can still listen to music while it's charging right, iFi?

 
Of course!
 
Just like the nano iDSD - your power up sequence determines if the iDSD runs on USB OR Battery power. Once full, it reverts to top-up charge automatically.

Yes, the SPDIF will be interesting.
 
More on this later.

 

[iFi audio]

Super cool. Will the xbass and 3D work through the rca outputs in addition to the headphone out? (Please?)

 
If we answer, we are giving more away than we plan to at this stage.
 
Take at look at the features and take a guess!

All iFi products are designed to be modular AND complimentary. So they can work with all good products out there, not just from iFi.
 
The micro iDSD is designed to work by itself for the lion's share of 'phones out there.

You are correct but the SPDIF input/output is not the only trick this little puppy has.

I have two machines to be portable 
 
 
But it is not a heavy load than for a portable computer is a computer, if it supports 
 
 
I think that is important so i voted half and half

I'm a 100% desktop user and voted as such. I'm looking for a product that will accept all resolutions via USB with as much quality as possible and convert to analog with as much quality as possible and then send to my audiophile pre-amp (via RCA) with as much quality as possible. I don't need or want anything more and I'm glad to pay up for quality if that quality is replacing the "more" that I don't need or want. I haven't yet found anything on the market that fits my bill, but I'm hoping the micro idsd comes close. My best to you guys at ifi.

18th April - Specifications announcement.
 
With new product development, things are never early, seldom on time and almost always late.
