I have an update.

I sent back my iDSD Micro  for changing of the board regarding my channel imbalance. The new board POT has a smaller amount of imbalance HOWEVER there is NO MORE PCM HISS in bit-perfect mode. I don't know if the new board has a newer firmware or it's different hardware?

I can't remember exactly but my new board has a gold plated USB smartcharging out female plug. Can someone verify if the series 1 boards have just silver usb plug? This could mean new hardware. (I know the digital in male plus is gold plated).

Overall very very happy with my iDSD Micro and kudos to James @ Avatar Acoustics for fixing it for me in a very timely manner with new a perfect product!


DAMN

Mine is gold


Mine as well

EISA award video

Little Big iFi in Berlin


Source: http://ifi-audio.com/audio_blog/little-big-ifi-jets-off-to-berlin-to-bring-home-the-eisa-award/



 
We have been a bit quiet of late - partly because of the micro iDSD launch, partly because of the show season and partly because of the EISA award for the nano iDSD.


 
With regards to the latter, given the very plush EISA awards ceremony, we just had to made a very brief video of our trip over to Berlin and share it with you all.


 
And we made it a little light-hearted too.


 
Once again, thank you to all the EISA judges and to our all our customers for supporting the nano iDSD.

I am very curious as well whether it is firmware or hardware that causes this noise in bit perfect mode playing PCM files.  My charging port USB is not gold and I can hear this digital noise in between tracks and during very quiet passages.
 
I know MLGrado mentioned earlier in this thread that he thinks noise in this mode is just a by-product of very limited processing, but now I wonder if there is more to the issue?

If I wasn't a tad remote I would do so myself, but can an iClub member request a clear answer from support.

If needed, would love to get mine upgraded at RMAF directly.

3 Steps: Micro iDSD "DoP pop" fix via Firmware upgrade

With native DSD playback, on some audio software playback programs, the "pop" issue is dealt with/not dealt with. This is an upstream characteristics of native, DSD playback and varies from system to system.
 
A little background here:
http://ifi-audio.com/audio_blog/pop-goes-dsd-why-does-this-happen/
 

We have coded a downstream solution for this upstream issue.

Preparation:
i. Ensure you have the latest iFi Windows Driver (v2.20) from here:
http://ifi-audio.com/download/ 

ii. Go here: http://ifi-audio.com/micro-idsd-ifi-xmos-firmware/
And save the firmware file “idsdv406.bin” to a folder of your choice (eg. Downloads)

 
iii. Connect the MICRO iDSD to a Windows computer  (OS X is not possible).


 
After this upgrade:
Win users (DoP)
With JRMC, the upstream “pop” issue from the source is virtually non-existent. With Foobar2K, there is still some residual “pop” hence we recommend JRMC until F2K catches up.


 
OS X users (DoP)
Using Audirvana, the upstream “pop” issue from the source is much reduced.


 
iPhone/iPad users (DoP)
With Onkyo HF player, the “pop” issue has gone. With Hibiki, there is still a residual “pop”.


 
We hope you find this firmware update useful.

 
We can also email through a pdf of the instruction sheet.

Thanks

Thumbs up for Ifi support and development.
 
Balancing time, money and quality spent on a product is no easy trick. I don't really mind bugs / issues on new products, as long as they are ironed out within a decent time span (weeks or months, not years). The combination of low price, high performance and bug-free is a lot to ask from a company when complex products are concerned. I'd rather wait for a few bugsfixes and get high performance, instead of more money going to longer QA before product release.

I will do the update later this evening, I wonder if this fix will also work in my Linux environment running Squeezeserver Lite with DSD over DOP option.
I report back later on that

Not sure if am I doing it right... But I have no pop sound with FB2k ever since I start using MP3 to DSD at Day 1.

Anyway, I often find the Minimum-phase to sound best with most of my tracks than the Bit-Perfect. Having a week of break from school here but something been keeping me busy, ordering a Project Sunrise III with five extra tubes from Garage1217 to pair with the Micro iDSD. Am extremely excited about it! Don't get me wrong thought, the Micro iDSD itself as a amp/DAC combo is great with plenty of power to spare but I want a tube amplifier to try with :D

I have a Sunrise III from Garage 1217 and thats what is use with the micro iDSD!
 

 
 
I think you won’t be disappointed. I use it with a Sennheiser HD 650. It’s definitely a darker tube sound you get from the Sunrise III but make sure you select the right tube for your needs, different tubes have different gain values and this amp can go loud. 

 
For me it’s very convenient to have two different superb headphone amps, with two different sound signatures. I usually swap around depending to what type of music I am listening at or what type of mood I am in.

Thanks for sharing!

Jeremy at Garage1217 was very kind and suggested me 5 tubes to try with their amp.

have you configured FB2K to use ASIO or DoP?.  ASIO has always been fine,it was really DoP which was the issue, the new FW has really helped a lot.
 
Big thanks to iFi for a fix to something they didn't cause :)
