Firmware 7.1.3 vs 8.1.3 vs 10.0.2

[ogs]

It is quite clear that 7.1.3 is very system dependent. In spite of what I had planned I did return to 7.1.3 from 9.0.1 a couple of days ago. 9.0.1 has been on my amp for at least 6 months. I believe the 7.1.3 CLIENT is the same as the one we call 7.1.3beta.
On my 250, 7.1.3 has more detail, bigger soundstage, better separation, better imaging and more bass than 9.0.1. It seems more dynamic, but also strangely louder than 9.0.1. To a degree that makes me almost suspicious that there is some form of compression involved. With reduced dynamic range, especially if low level information is amplified, detail will be clearer. I will have to go back to 9.0.1 to check this although I find it highly unlikely that Devialet has released software that includes compression. Even beta software.
Other than that I really hope 10.x on the new v6 Pro hardware will be similar to the character of 7.1.3, but with the refinement of 9.0.1
