Thanks for that.
I just put in one of my 2L.NO blu rays which has 7.1 96/24 DTS MAHD and 5.1 192/24 DTS MA HD and it would seem the Datasat will not apply processing to any signal above 96/24. But this is an error on the software as the unit is applying Dirac which means the signal is getting downsampled to diracs capabilities of 96/24.
Not that this really means anything in the real world as I have hardly any content above 96/24 and all that I do have I probably wouldn't really want to add further processing to anyway.
But this leads me on to the next thing.
Since I have had my new Datasat amp, previously coming from ADA amps I have noticed a really annoying thing.
On a lot of blu rays and TIVO / Netflix or Sky Now TV I notice a fair bit of what sounds like distortion on the centre channel around voices. Particularly female voices and people who are shouting.
At first I thought I had blown my tweeter, or damaged it as its that kind of overly driven, resonating distortion. I first noticed when watching the breaking bad series on blu ray
And the volume doesn't seem to matter.
Thinking it was a damaged tweeter I shifted the speaker mapping around so that the left or right front was acting as the centre and this distortion was still present.
So that led me on to Dirac thinking perhaps it's boosting some upper frequency too much due to a bum calibration session. Not the case as this still happens with Dirac off.
But, I do not get ANY kind of distortion when playing music thru my nad streamer, male or female voices being played back near reference are all clear as day.
So I thought perhaps it's an HDMI issue.
But again, if I play back one of my sacds, DVD audios or any of my dolby or dts blu ray test demo CES disks again, no distortion.
So this leads me to one conclusion. Im hearing poor mix down and clipping / over compression of the mics used for recording. Which I just find really odd.
All my previous amps have been of high quality like the Ada 2502s. I can't believe that the Datasat amps has that much more detail and resolution that I can now hear bad mix downs where previously I had been completely unaware of such distortion.
