![]() Controlling the analogue hardware volume of the Meridian Explorer (that is essential for bit-perfect and, hence, MQA) was not possible. With moOde 2.6 installed I experienced the same problems that I had earlier with the other distro's. Then I came across moOde and read about Tim's very good support. Volumio did it best, but was unstable- sometimes the DAC was not recognized by the system, sometimes it was freezing. But none was capable to drive the Meridian Explorer2. I tried different images like rune-audio, max2play, volumio, etc.Įach of them had minor and major bugs, goods and bads. So the one missing piece in my setting was a bitperfect linux distro ready to drive the Meridian Explorer2. ![]() But at least the MQA file is considerably smaller in size. I dont know if a MQA 192khz audiofile sounds much better than a non MQA file at 192khz. But if you decode those files with a MQA-capable DAC you get full advantage of the highly compressed hires files. They can be played with any audio-gear thats capable to decode these formats. MQA is a not really a new audio-codec, but a hardware controlled decoding on a new level. wilma capacitors), the apodizing filter, etc. If you dont care about MQA, the Meridian Explorer2 is still worth to be considered, because of its high quality audio components (e.g. Looking for a hires DAC I read about the quite new MQA (master quality authenticated) standard and decided to give the Meridian Explorer2 (MQA capable) a try. Lossless Switcher is available free of charge from Neo’s Github repository.On my odyssey for a good sounding, yet affordable audio streaming solution I came accross the raspberry pi and its multiple linux distributions that were highly adopted for audio and multimedia streaming. Vincent Neo warns that “there may be short interruptions to your audio playback, during the time where the app attempts to switch the sample rates.” He also says that his app has yet to be tested on an M1 Mac. Lossless Switcher reads the sample rate of the incoming Apple Music stream and then automatically sets the corresponding sample rate in the Audio MIDI Setup app. Once installed and running, the app runs in the menu bar at the top of the screen, next to the clock. Vincent Neo’s LosslessSwitcher app “switches your current audio device’s sample rate to match the currently playing a lossless song on your Apple Music app, automatically.” And this is only achievable on MacOS by manually specifying the Audio MIDI Setup app’s sample rate on a track-by-track (or album-by-album) basis. Only when no resampling takes place do we have what is known as ‘bit-perfect playback’. Resampling can subtly alter the sound of a stream heard on a more resolving hi-fi or head-fi system. If we hit play on a 44.1kHz file but the Audio MIDI Setup app is set to 96kHz, we gain dummy data (and arguably lose again). If we hit play on, say, a 192kHz hi-res lossless stream but the Audio MIDI Setup app is set to 44.1kHz, we lose data. Upsampling and downsampling are collectively referred to as resampling.
