Hi Gents

Brief experience with 568.2mm:

I must admit to being late to the party on this one, but it's been very interesting. Changing the parameters by opening your .msf config file in Wordpad on Notepad is easier than I expected, and it's not in hex code either, just plain decimal; a level of -2.5dB will read as "-20", so adding 3dB means that the figure would be changed to "05".

The system is 8k mains, 6k centre and 5k rears. I changed the dB calibration levels as follows:

L -2.5 > +0.5
C 0.0 > +3.0
R -3.5 > -0.5
RR -2.5 > +0.5
RL -2.5 > +0.5

Listening in Trifield, first impressions were very positive, it definitely has the same effect I enjoyed with the 518 and it's digital gain feature. You can hear more detail, enjoy an improved soundstage, and everything sounds more engaging. However, a few tracks in and clipping occurred. The CD was Stacey Kent's "Breakfast on the morning tram", second track. Her voice clipped a few times on the centre channel with audible distortion. I changed the centre Eq from 1 to Flat as suggested previously, but the problem persisted. The same album also sounded a little forced on sibilants, but pretty much everything else I listened to sounded better.

I've now reduced the calibration settings by 1dB and the clipping on that CD is less pronounced, but still there to an extent. Of course, losing that dB means slighly less of all the other improvements, so I'll need to do some further tweaking, but Trifield seems to be the preset which exhibits this overload, as neither Direct nor Music seemed to suffer.

I'll post back more info when I get things sorted completely, but I'm struck again George, this is a cracking piece of work, and hats off to you for having the tenacity to track down those missing 3dB!

Cheers

George
