    xDuoo XD05 Plus: an interesting update

    My main complain about the bluetooth add-on was that it blocks the charging port and analogue out. But i noticed you can point the bl05 up so it doesn't block those ports anymore. I'll bet most know this tip but for who who don't, voila.

    My first portable headphone amp... totally confused!

    Personally i would forget the Topping NX4 and the Mojo because of the lack of bluetooth possibility. Not needing a wire between your smartphone and amp/dac is so nice imho. Ldac bluetooth codec sounds very good. Lossless with 320kbps source material.

    xDuoo XD05 Plus: an interesting update

    Untill someone passes succesfully a double blind test with 2 Xduoo's, one with the stock opamp and one with an exotic opamp, i remain sceptic about the subject. I have seen experienced audiophiles failing in double blind tests with $100 vs $10.000 amplifiers let alone that people can hear a...

    xDuoo XD05 Plus: an interesting update

    I'm a guy who can't hear a difference between Ldac Bluetooth and wired, let alone opamps. I'm happy with how the Xduoo xd-05 plus sounds stock, so i will pass the opamp stuff. And you can't compare fast (switching opamp takes time), which makes it impossible to hear a real difference anyway...

    xDuoo XD05 Plus: an interesting update

    Got it back with switching SmartThings off and on again.

    xDuoo XD05 Plus: an interesting update

    I used to see the battery percentage of the Bluetooth dongle on my smartphone screen (Samsung SmartThings screen), but it's gone and don't know how to get it back. Anyone?

    Is bluetooth aptx perfect for 320kbps mp3?

    Hearing incoming email notifications through the music looks like evidence. This won't happen though if you put 'do not disturb' on.

    Is that Muse 02 a dual or two single amps?

    Is bluetooth aptx perfect for 320kbps mp3?

    Well, in an ideal scenario that happens only once, in the end dac. In case of bluetooth streaming with an Android/Apple phone, it happens twice in case of an AAC source. I wonder if it also happens twice in 'do not disturb' mode, because Android doesn't mix the notification sounds in the music...

    Is bluetooth aptx perfect for 320kbps mp3?

    In 'do not disturb' mode Android doesn't mix notifications in the music anymore, but the question is, does it still do the AAC > PCM conversion then?

    Is bluetooth aptx perfect for 320kbps mp3?

    I have just read elsewhere that even if you have an AAC source (Tidal high Q) and a AAC codec in your Bluetooth device, Android and Apple iOS as well will decode the stream to pcm first so they can mix notifications in the music played. That's a bummer.

    Is bluetooth aptx perfect for 320kbps mp3?

    Got AAC working now on the smartphone, had to disable a certain setting in the Android developers menu. I did my best to try to hear any difference between Tidal high (320kbps AAC) by bluetooth, versus USB cabled Tidal hifi. I couldn't. Bluetooth rocks. Well, at least for my ears.

    Is bluetooth aptx perfect for 320kbps mp3?

    On my Androidphone i can only get aptx and ldac working. In the developers menu i can select aac, but that setting won't stick. The bluetooth receiver i got on the external dac/amp should support aac though.

    Is bluetooth aptx perfect for 320kbps mp3?

    I said mp3 but that wasn't correct, Tidal and Spotify use AAC and Vorbis. But this doesn't change the question i understand. All these will be decoded to pcm and then to aptx? I think it's best then to use Tidal HIFI as a source which is pcm already. One conversion less.

    Is bluetooth aptx perfect for 320kbps mp3?

    Bluetooth Aptx is 352kbps, which seems perfect/sufficient for streaming 320kbps mp3. Is this correct or will Aptx-HD or Ldac offer more benefits in case of mp3 sound?
