    Beta mark in the app

    Looks like beta FWs are now marked as beta in the app. It's also possible to opt-out after touching the FW version field:

    My WiiM Amp tests, chapter 2

    A new unit is with me. Because new device is too cold to be powered, I can focus on external differences. Both units are almost undistinguishable. One difference is reversed channels on RCA inputs. Second one is a class II power supply mark printed on the bottom. I've seen units with reversed...

    My WiiM Amp tests

    Well, not finished. Yet. But let's start with some facts. The Amp seems to be a class D BTL H-bridge amp with a single power rail (find someone smarter than me for an explanation), and with an advanced temperature monitoring through some sensors to deliver "optimal performance and safety" which...

    New Pro Plus FW - 4.8.532839

    These new features are quite weird to me.

    My WiiM Pro Plus 2nd sample test

    Note: due to the fact that my sample unit had significant problems with various PSUs and this was fixed with the FW update, the entire post has been corrected and updated with the most up-to-date measurements. As you can see I finally got the second sample of the Pro Plus with promised...

    My WiiM Pro Plus (+) tests

    At a moment I can tell that my sample unit has an increased space around the coax socket. And a glossy finish of the chassis. Stay tuned :) Part 0 - a test gear possibly involved RME ADI-2 DAC FS, ESS edition miniDSP Flex, RCA edition E1DA Cosmos ADC, A grade PicoScope 4444 Intona 7055-D...

    Fade effects

    Fade-out: Fade-in: All on the Pro. First row - source audio, next one - content played with LMS and DLNA, gapped playback, then - content played with WHA, and the last one - content played with LMS and chromecast. The scenario above is when the stream starts or ends, ie. sample rate changes.

    Popping/clicking between songs

    I've started to face nasty popping on my Pro connected to miniDSP Flex. It can happen when songs with different sample rates are played, no manual switching is required. It can be captured on the DAC in the digital domain: Sometimes it's rather seldom, sometimes quite often, I do not see a...

    Metadata don't refresh when DLNA is used in gapless playback mode

    My WiiMs (Pro and Mini) don't refresh song metadata when audio is sent via DLNA/UPnP and gapless playback mode is used with SetNextAVTransportURI. I've tested it with LMS UPnP bridge and BubbleUPnP. The metadata is correct only when starting the song manually, but during the gapless playback it...

    Coaxial SPDIF experiment

    to get an eye-pattern. An ordinary RCA analog cable used, terminated with 50 ohm and a PicoScope 4444 oscilloscope working with 20 MHz BW. 48 kHz: 96 kHz: 192 kHz: Any thoughts? :)

    Chromecast vs DLNA (WiiM Home app, etc.)

    Volume at 100%, no EQ, digital output. Chromecast tested with LMS. Both ways give a fully transparent output in the frequency domain, no audio alteration at all. It looks different in case of time domain. Two songs, the same sample rate and bit depth - 96/24. Case 1 - second song. Beginning...

    Gapless mode (setNextURI) issues for UPnP interface

    @WiiM Support Gapless mode seems to behave unpredictable for both WiiMs especially when audio streams are controlled by UPnP bridge plugin in LMS. Author of the plugin suspects that "The issue is that the UPnP stack of the WIIM (I don't have one) seems to be a very precarious. For example...

    Limiter effect

    @WiiM Support Can you please do something with the limiter in EQ mode? It would be nice to see this instead of this for flat EQ.

    SPDIF resync / clock locking during manual tracks switching

    which can result in clicking / popping / static noise as it has been reported in some threads related to both Pro and Mini. For Spotify there is no such issue regardless of songs being played over Connect or from the playlist internally in Home app. For Tidal Connect there is an SPDIF resyncing...
