I have a beta version of Deezer running on a MacBook. I have a wireless connection to a BeoSound Essence Mk2. The software version of the Essence is 1.1517474.98801383. The Essence is connected to a pair of BeoLab 5's. I have three different audio quality options in Deezer. Standard 128kb/s, Better 320kb/s and HiFi 1 411kb/s
I have toggled between the three setting and have to be honest and say I can't tell the difference. I think I can hear a slight difference between 128 and 320 but its so tiny it could be in my imagination. No difference between the Better and HiFi setting
Hi David - I agree that BL5s are wonderful, however I wonder if your experiment is valid (of course I may have understood).
Let’s set aside the use of beta software and assume there are no bugs 😁
It sounds like you are Airplay-Ing or Bluetooth-Ing from the MAC to the Essence ?
There have been discussions on the forum over the years about whether AirPlay(1) is degrading the quality of the sound - and many recommend wired connections to help ensure no compromises on the signal path.
I believe once the signal arrives at the Essence it’s DSP is invoked - of course if the signal from the Mac was pure analog then the DSP in the chain would be the Mac’s not the Essence’s - the Essence would pass the signal straight through.
A better path would be optical out of the Mac and into the BL5s - in that situation I believe the DSP housed inside the BL5 is used.
I believe I could discern the difference between vanilla Deezer and the HiFi version. And certainly my network groans a bit under the difference.
And I believe what Deezer HiFi is delivering is superior to a CD on the BeoSound 4.
Today I have moved to a pure optical chain from my Core (which accesses Deezer directly over the Internet) to my BL20s. Of course the 20s are nowhere near as good as your 5s.
For testing I have been using a “HiFi audiophile” playlist on Deezer. So far I am very pleased with the quality - I believe my BL20s are expressing more bass than when Core was wired by PL cables (and where the Core’s DSPis used). The resequenced (I am only listening to songs / artists / recordings I am familiar with).
One other test I did is use Geoff Martin’s recommended “Bird on a wire” as a first test. I found that I had to remove the volume limit (72) as for that recording I need to go up to about 80.
I hope this helps your own investigations ...
