The DAWs: ProTools 9, ProTools 10, Logic 9, Cubase (latest) and Digital Performer 7.24.
All installed on 5 equal Macbook Pros running optical O/P to a switcher to two Genelecs.
30 tracks multitrack projects all with equal panning and gain. (pan law etc were carefully compensated for)
We tested 2 different projects. One tight rock song and and one jazzy more open song.
This test took 2,5 hours and the material was tested on 30+ members of the Swedisch Sound Engineer Society. All professionals.
We compared different looped material in sections, played on MBP nr 1,2,3,4 and 5 and even randomly.
The original projects were recorded 96/24 in PT and converted to 48/24 in PT and this files were imported to the DAWs.
The test also included a listening to 6dB masterbuss overdrive to see how that was processed internally in each DAW.
After every listening part we all got to say what we prefered and why.
The verdict:
The MBP nr 1 always was the most liked and than sometimes also in combination with nr 4 and nr 5.
MBP nr 3 was most often disliked and sounded "compressed".
MBP nr 2 nobody really liked. Only once by one person..
I made them include DP in this test as I really wanted to know myself how DP would compare in this line up.
I was one of those that didn't know what DAW was on what MBP. I heard the engineers say/yell "nr 1 is the best" all the time. I agreed.
It had the most depht, best definition and fullest sound. It was really noticable.

Well. After 2,5 hour we finally got the results.







MBP 1= Digital Performer
MBP 2= ProTools 9
MBP 3= Logic 9
MBP 4= ProTools 10
MBP 5= Cubase (latest version)







OMG was I surprised!!!! I couldn´t help shouting out loud when DP by far was the most liked in this DAW sound test!
A lot of jawdropping amongst the engineers... "Whut?????!!!"
A big smile on my face..

Finally everybody gotta understand why

I feel so proud and delighted about this DAW test results as I prompted to the SSES board they should include DP in this test.
