I just got back from testing an Audi B&O 3D Sounds System in a Q3 Sportback. This has 15 speakers plus sub with a 16 channel amp.
I loaded a 16GB USB 3.0 stick with an assortment of test tracks in FLAC format, all same files I now have on my home system, tagged with high res album art etc. I didn’t mod them in any way, so the FLACs will be using FLAC compression level 5 or 6.
- Channel Tests (Quad, Quad with silent Centre, Quad with silent C and LFE, 5.0, 5.1 and 7.1)
All with sample/bit rates: 44.1/16, 48/24, 88.2/24, 96/24 (and one with 192/24 5.1)
This was to check how it would handle all the channel mixes and formats I have.
EVERY file played correctly! With correct channel assignments. Not one glitch, even quad 4.0 played correctly. Pass.
- Various Artists Test Tracks (A full range of channel, sample/bit rates - quad to 7.1
This was a proper listening test. I played a bit of each song that I know intimately from my system at home. All played and sounded like they should. All sounded very discrete (I chose discrete tracks) with clarity, great dynamics and good LFE. Better than the Jag E Pace I tested last year by a mile. Pass.
- Surround Albums (7 albums from 3 Artists) - various channel, sample/bitrates
This was to check how artists and albums would appear in the user interface.
These all showed as I wanted, album covers at the Artist level. I could view Artists and it showed both number of albums and songs for each artist. Pass.
When I inserted the USB there was a very, very slight pause and I thought it obviously had not scanned the tags, but it had! The UI knew which artist I had and their albums as I could sort and filter on this metadata.
I have to say I came away very impressed with its ability to play everything a threw at it and the sound quality was truely excellent. The UI was fast and responsive.
My next new car will be an Audi with the B&O 3D Sound System! My wife and I are doing a test drive on Friday.
BTW: For MCH FLAC on the B&O you also need the MMI option.
