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. :beerchug:

 

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

post #337 of 2397
Indeed!!! Will there be a gain switch for the iDSD micro as suggested or the amp doesn't really need one? @.@

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.

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.
