No, these are in 100% analogue.

Right on, from what I gather, applying processors to the analog signal means no bit loss. I've been super pleased with performance of these feature on my micro iCAN and just had to make sure the iDSD didn't offer any "additive" effects in the digital pathway. That being said, I think it's definitely time to start saving for a Pro iCAN. :) ...while I'm here...any comment on the strength of the Pro iCANs Xbass switch vs. the micro, and how this feature may be influenced by an in-line analogue EQ like the Schiit Loki? I.e. will I see a linear response in the strength of the XBass with the Loki (+12 dB @ 20 Hz) or is the XBass still strictly going to be additive? Hope that makes sense, I'm trying to go all out bass head for a home theater setup right now.

Hi all,

Now that it has been out in the wild for a few months, what feedback do you all have on firmware version 5.30 "Cookies and Cream"?

I don't have any access to MQA files, so that portion of the firmware does not have any added value for me at this time- does anyone have any comments on other changes (good or bad) in behavior of their respective iFi device not related to MQA? I have an iDSD BL currently on 5.2, and am weighing whether or not to perform the upgrade.

Thanks in advance for your comments and feedback!

When upgrading I believe you lose 768Khz and DSD512 support. That is the trade off (correct me if I am wrong). >>It says "if you require DSD512/PCM768 without MQA, then use version 5.2". There should be no other changes in performance, can iFi confirm this?

If you do not use MQA files or streaming, I suggest staying on 5.20, that is what mine shipped with (rather new unit) and what I'll keep using. It works perfectly, I see no reason to update.

That is correct. It's either DSD512 without MQA or DSD256 and MQA, but no change as far as sound goes.

Hi
Another anomaly has occurred. I can no longer play DSD .dff files in foobar. DSD dsf are fine. I have not altered foobar since I was last able to play .dff.files
Sound is being played by foobar as it is registered on the visualization window but I cannot hear the file.

When I play a flac or dsf file the iFi (by AMR) HD+ USB Audio output is identified by the sound configuration in windows. As soon as I attempt to play a .dff file it disappears.

Update: I played with the output settings. If i change ASIO to AISO iFi (by AMR) HD+ USB Audio and swap Tools - SACD setting from DSD to PCM it plays DSD .dff but not DSD .dsf

I am stumped any ideas welcome

Further update
i followed the instructions on https://diyaudioheaven.wordpress.co...-part-3-new-experimental-sacd-plugin-v-0-9-x/

I have replaced the ASIO driver with the DSDTranscoder and set foobar up to Mode 2 (not using the DSD processor as I believe the author suggests that the idsd performs better without this option:
trancoder option no dsd processor.JPG

All file types play but two more issues - I cant use the graphic equalizer with DSD files it works fine with flac. My preset really helps to enhance my akg 702.

Secondly the ifi control panel sample rate doesn't correspond with the foobar reading with DSD multi-channel files. I am sure it correlated before.
I need a bit of technical insight. Thanks

Hi, could you tell me if the idac2 supports dsd 512 with the 5.2 firmwares the xdsd does? I notice both only have one dac chip but it says the dac 2 doesnt officialy support 512
I own both micro iDAC2 and xDSD and iDAC2 does support upto DSD256 even firmware 5.20. BTW, I have never ever seen native DSD512 sources so I do not understand why people are interested in DSD512 capability.
