And therein is the fundamental issue with user interface design: there is no such thing as one design that is "obvious" to everyone. Wiim here is going with a "wizard" design, where the user is asked a sequence of questions that is each simple to answer, and Wiim decides what the final logical...

What you are hitting is the difference between a logically complete set of options, and a set of options that make sense to people. 1) If I own an MQA capable DAC, one that has a decoder and renderer (first and second unfoldings), then Wiim would be happy to just pass the original bit stream...

With the firmware update of 12 February 2023, now the white status LED (connected to wired network/wifi) is clearly dim when the system is on standby (no music playing), and gets bright when I play something. The white light then gets dim again after 30 seconds, my setting for stand by mode...

This is correct. I followed the step by step direction from "skeptic mike" (post #6 on this thread). It worked. I was at one point a systems engineer working at Microsoft, so I may have an above average ability to understand Windows arcana. :-)

So I did another test of bit rate/bit depth differences: "Revolver" by the Beatles, in particular "Taxman," the first track. Samples: FLAC 44.1 kHz/16 bit of CD from 1990s (1987 US Parlophone release/mastering) Tidal 44.1 kHz/16 bit; 2009 remaster Tidal 44.1 kHz/16 bit; 2022 remaster Tidal...

Looks possible. May require the paid version of AssetUPNP. "m3u and pls playlists are supported." These are not the native format of Apple playlists. Rumor has it third party apps will export Apple playlists to m3u format. https://www.dbpoweramp.com/Help/AssetUPnP/advanced.html

I liked dbPoweramp when I was ripping my CDs to FLAC files, so I suspect AssetUPNP is a reasonable choice for a UPNP/DLNA server. I started with Minimserver when it was free, and I don't mind paying a bit annually for software I use regularly (I was in the software development business). d6jg...

I have about 6,000 tracks (550 CDs) in an minimserver on a Windows 10 PC. It scans the directories fairly quickly, building an index. Minimserver does not move any files, or write any files into the directories where the files are. I would check on the Minimserver support forums, but I suspect...

The Wiim Pro uses UPNP /DLNA (Universal Plug and Play/Digital Living Network Alliance) protocols to stream content from local servers. As far as I can tell MacOS/iTunes does not natively support this protocol. However, there are many servers you can put on a Mac or Windows computer to be music...

The LED statuses for the Wiim Pro definitely need some work. I have Wifi disabled, no blutooth device paired, and no optical SPDIF or Line in input connected (SPDIF is output). I am using the wired ethernet only. Mostly the status LED is on solid white, with no noticeable dimming when in...

I was looking at the IEC 60958-3 spec, the first version of which is 1999. I stand corrected there was an earlier 1989 spec from IEC, IEC-958. I didn't realize you were posting information about the pro spec with the sample frequency bits part, hence my confusion about the seemingly incompatible...

One has to have a system that is capable of going to 20 kHz, and down to 20 Hz, if one wants to have a chance of hearing all the samples. My system (described above) has tweeters rated as flat to 22 kHz, and the subwoofer definitely goes down to 20 Hz. The amp is rated as basically flat from 20...

In the consumer electronics space, there are *many* devices that were created before the current specs were written, and with which even modern equipment will want to be backward compatible. Note S/PDIF was defined in 1980, and Toslink in 1983. I bought home audio equipment in the 1990s that...

Agreed. As far as I can tell, the Wiim Pro does its digital job well, with EQ off and fixed volume, in taking in losslessly compressed or uncompressed stereo digital streams, and putting them out over the optical link in bit perfect form. The Wiim Pro even seems to do the MQA unfolding...

Note: the reason a "compressed" MP3 file works for this test tone file is because the tones are pure sine tones, exactly one note at a time with no overtones, the easiest sound to compress without loss of fidelity. If you feed the output of this MP3 after decompression into an oscilloscope, all...
