Hello,
I agree with you, a Bluetooth connection does not allow the transmission of CD quality audio files, its bit rate is reduced to around 400 kb/s, even if lossless compression such as FLAC is sent.
Devialet's soundbar uses Bluetooth 5.0 with only SBC and AAC compatible codecs.
It allowed me, however, to assess the sound quality of the Devialet soundbar despite everything.
Of course, I noticed when listening that some sounds were diffuse, because the soundbar has a slightly accentuated high midrange, which is what gives it its signature when watching a movie, but honestly I didn't never heard this sound quality on any other sound bar so far while streaming music.
To have a high quality sound in Bluetooth, two formats are possible, the aptX HD (24 bits/48kHz) developed by Qualcomm and the LDAC (24 bits/96 kHz) invented by Sony.
If your computer is equipped with an older generation Bluetooth controller, you should consider using an apt-X or apt-X HD Bluetooth transmitter to significantly improve listening quality.
I still have in my possession two Focal Easya wireless speakers which have Bluetooth aptX, purchased 8 years ago and which are no longer on the market.
I keep them, because they sound different compared to my Devialets, I admit that I listen more often on the Devialets, my search for the best sound stopped there.
For less than 100 euros, as an example, you can possibly turn to a receiver like the NorStone BT Connector Hifi APTX which brings together analog and digital connectivity, moreover it is switchable as a Bluetooth transmitter to possibly send the sound from your television. to a Bluetooth headset.
Furthermore it is very important that the transmitter and the receiver are both compatible with the desired codec, otherwise the SBC compression technology (of lesser quality) is used.
Owners of iPhone, iPod touch or iPad can take advantage of the AAC codec, of an intermediate quality, provided that the Bluetooth receiver supports it.
For the wireless broadcasting of sound if we go through Airplay, we will have an audio quality limited to 16 Bits / 44.1 kHz even if the file is encoded in 24 Bits / 96 kHz, it will always be delivered in CD quality at 16 Bits / 44.1 kHz.
With DLNA, this wireless broadcast is able to accept all files up to 24 Bit / 192 kHz as well as DSD 5.6 MHz, if your equipment is compatible, you also need a good high Wi-Fi connection .
And as I mentioned, Bluetooth with APT-X codec has a resolution equivalent to an audio CD (16 Bits / 44.1 kHz), it is of course necessary that all Bluetooth devices are APT-X certified.
