iFi iDSD Micro DSD512 / PCM768 DAC and Headphone Amp. Impressions, Reviews and Comments.
Feb 18, 2016 at 12:02 AM Post #5,313 of 9,047
Need some help. I just bought a tube amp/... RSA Raptor. What type of cable would I need to use the Micro as a DAC only connecting to the Raptor?
 
SPDIF out to RCA on the Raptor? 
 
Any help would be appreciated.

You need a common RCA cable.
There is one in the micros box!
Set it in direct mode from the switch below the RCA output (while turned off) and you are good to go...

I did what you posted but I still get no sound. does my music player have to be off too...to I turn the amp on first? and then the Micro and DAP?
 
All I ever listen to is IEM's and I've never used the Micro as a DAC only

Not SPDIF-out, that's digital output. Sending digital signal to a tube amp of course won't give you any sound.
 
Analog output are the other two, the red and the white RCA socket.

Unfortunately I have never used the coax input of the micro. If you are listening through this I can not help you.
You can try connecting through usb to a computer just to make sure that the amp works fine.

Here's my setup:
 
I have a Sony NW-ZX2 line-out to my Micro with the Sony WMC-NWH10 USB Conversion Cable.
 
I have the RCA red/white connectors connected to the Micro and then to my Raptor(red and white connectors match color)...is this correct?
 
Is there a sequence turning the different components on? ie..turn the amp on first,  then the DAP and last the Micro?

Turn both the ZX2 and micro iDSD on first, follow by connecting the WSMC-NWH10 to micro iDSD, then connect the other end to ZX2. I am not too familiar with how the Android system runs on ZX2, but there is a possibility that you need to enable or detect USB devices in the system setting.

Unified Firmware 5.1

Gelato and then some
 
 

 
Southport, UK – 18th February 2016
 
 
Latest Unified Firmware v5.1 ‘Gelato’ (for Stereo 50 /micro iDSD / micro iDAC2 / nano iDSD)
 
The very latest in-house firmware[1] version 5.1 for ALL iFi products[2] is available:
  • All-new XMOS ‘deep-core processes’ software for different behaviour of SPDIF (after XMOS previously modified the USB section).
  • Enables DSD256 for 48kHz based sample rates up-conversion when using DSD256 in DoP mode.
  • Fixed issues surrounding DoP standard; including ‘clicks’ when changing tracks and sonic differences to native DSD and other minor bug fixes.
 
For customers with particular requirements, there are two firmware sub-versions (PLEASE read carefully):
 
2) For nano iDSD and micro iDAC2 v5.1A - Enables DOP256 operation
  1. This enables DSD256(DoP) operation, which requires 768kHz PCM at the USB interface level.  
  2. Nano iDSD and micro iDAC2 CANNOT decode 768kHz at the DAC level, but they can all be programmed to receive 768kHz PCM at the USB interface level hence enable DSD256(DoP). 
  3. With 5.1A, the user MUST make sure to manually alter the PCM audio settings correctly (especially Mac), otherwise there will be no audio output at all.
  4. In other words, when playing PCM files, the sample rate must NOT set to be higher than 384kHz.  Only set the sampling rate to 768kHz when one wants to play DSD256(DoP).
  5. There is no need to use this firmware if one uses ‘native mode’ (not DoP) to play DSD or DSD files are not played at all.
  6. Do NOT use 5.1A on any other products other than nano iDSD and micro iDAC2.

3) For iDSD micro Firmware v5.1B - Disable Sleep Mode (Smartphone users ONLY)
  1. This is strictly for Smartphone users ONLY, there is no other reason to use 5.1B on the micro iDSD.
  2. The micro iDSD micro will try to recharge while in Sleep Mode (e.g. when connected to a PC).  If connected to a Smartphone which is ‘seen’ as a computer, it will recharge via the Smartphone.
  3. 5.1B disables the Sleep Mode within the micro iDSD; hence it will no longer try to recharge during Sleep Mode and flatten the Smartphone’s battery.
  4. Do NOT use 5.1B on any other products other than micro iDSD.

[1] WARNING: Do NOT flash non-iFi products on the XMOS platform with iFi firmware!

[2] iFi Native DSD-capable DACs so original iDAC excluded so do NOT update using v5.10.

  The windows link for the iDSD doesn't look like its updated? 

 
Hi,
 
http://ifi-audio.com/micro-idac2-ifi-xmos-firmware/
 
The same 5.1 firmware can be sourced from here.
 
We'll update the micro iDSD asap.
 
Thanks

Also, now on http://ifi-audio.com/micro-idac2-ifi-xmos-firmware/ it is said confusingly (in the beginning):
 
After having passed extensive testing, the iFi XMOS firmware version 5.1 ‘Vanilla’ is ready for public download.
This latest firmware v5.1 ‘Vanilla’ is unified...
 
and little below
 
1) Firmware v5.1 ‘Gelato’...
 
plus
 
firmware dowloadable in http://ifi-audio.com/micro-idac2-ifi-xmos-firmware/ is called iFi_XMOS_V5.1&V5.1A.zip
and firmware dowloadable in http://ifi-audio.com/micro-idsd-ifi-xmos-firmware/ is called iFi_XMOS_V5.1&V5.1B.zip
 
so, are they different?
