So I just upgraded to a new (non-iFi) headphone amp, and my suspicions were confirmed when I connected it to the iDSD Pro. No matter what kind of filtering or processing I do to the USB signal prior to the iDSD, streaming music through the iDSD's ethernet connection (using the dreaded DSD-incompatible Muzo app) sounds more relaxed and natural. I heard the same difference when using the iDSD with an iCan Pro, but told myself that was due to my associated gear.

I feel a bit miffed. My fancy network server with an 8TB SSD, connected directly (or via iDefender+/iGalvanic/other USB devices) via USB to the iDSD (whether using Roon or Euphony Stylus), sounds inferior to streaming my NAS music through a nice ethernet cable (with an ethernet filter) while using Muzo. In addition to ethernet, using a microSD card with the iDSD sounds superior to the USB input as well.

On the one hand, I'm glad that I've discovered the best-sounding uses of the iDSD Pro. On the other hand, my server isn't hacking it with this DAC, even though the iDSD's USB connection has galvanic isolation and all that.

YMMV, of course. Maybe it's just my system?

It might be, but many people would agree that music via ethernet right into a DAC can sound better than USB. And as for microSD playback, that's a very broad subject, but there are enthusiasts who really don't consider anything else

It's a shame "blue os" doesn't work with the pro iDSD

It´s a shame that i´ver never read about an 8 TB SSD before!?
There are a few features i´ve expected as a standard...But more i wait for an answer to my ticket for over a month now...

Does anyone have SNR / THD values of the IDSD to hand ? trying to get optimal ENOB value for use in HQ Player

The iFi micro BL was shown to truncate to 18-bit using shaped dither. So I would shoot for 18-bit..

Had it on 18 lucky eh i’ll see if i find anything else , most decent DACs are 18/19 anyway these days

"blue os"

Can you please tell me what's that?

I'd have to double-check this.

I think he means BluOS. It's like Sonos' multiroom OS they use with their smart speakers, but BluOS is used by NAD and BlueSound digital equipment.

Aw, okay, thanks. This makes sense

My OLED display of Pro iDSD does not show anything after I swapped the tubes inside. I have checked that there was no disconnected part.
Have I damaged something inside?

Check your haven’t just turned the display off ? you can do it by clicking the source button i keep mine in that standby mode , not long hold as that’s polarity change

When you change source does it still not come up then something is up if that’s the case

Tried with no response. My Pro iDSD is running normally except the OLED display, weird

Although I don't know how to help you out, you might let us know here: https://support.ifi-audio.com

Perhaps our tech staff saw this issue already and they have some workaround.

Hi community
Did anyone try to connect external 10mhz reference clock to IFI PRO IDSD?
Did it work fine for you? Which BNC cable did you use?
I tried to connect MUTEC REF 10 to my IFI PRO IDSD using several BNC cables and it did not work well for me. The DAC flashed error message "Extern sync clock error".
I consider to try with Sotm SCLK-OCX10. I ask to learn from your experience before I do so...
