iFi audio,
Could you kindly pass along a feature request to the software team at iFi? After purchasing the xdsd, it appears that in fact the led indicator does not operate as shown in the product manual. As of software version 5.30, all PCM data will show up as green on the audio format LED. In my case that makes the unit rather less useful because I have a collection in mp3 format (which I am slowly working to eliminate) and another collection of CDs converted to FLAC 16/44.1. Since I don't use DSD and probably won't use MQA (MQA is lossy), the only other common hires format is the higher bit, higher frequency material (e.g.), 24/192.
Since the audio format LED will show green no matter what I play, it is basically a placebo, and in any case will be unhelpful in removing mp3s (which I hate) from my collection since mp3s will be rated as the same as 24/192 files: green.
And can you also ask when this feature request will be implemented and available for download?
Sigh.
