Hi Recruit
I've spoken to Meridian and the tech told me that the G91 WILL NOT upsample CD used as a surround system with DSP speakers. Likewise for DVD and only upsamples analogue inputs into it.
I tried it as a digital out only and it does upsample CD's so it must use it's power doing the surround thing which disables the upsampling.
So it seems thats not broke then, just the other issues I seem to have must be software.

Cheers

This was the mode in which I auditioned the DSP5200s. My G91 was set to Type 6 to use it as a surround processor to generate Trifield. I was mostly playing CDs though also played some DVDAs including some 96kHz/24bit. Thse sounded good but the available selection didn't include the female vocals tat highlighted the treble issues on CD playback so I can't confirm this is definitely an upsampling issue.

When I compared to the B&W speakers the G91 was in Type 0 used as a 2 channel analog preamp with upsampling delivered to the analog outputs.

This could explain some of the lack of treble smoothness when listening to the DSP5200s. But a big part of the rationale for G91 + DSP5200 would be to avoid the costly G68 purchase. If this is necessary to get CD upsampling and smooth the treble, then the value equation changes considerably, away from DSP speakers. You can no longer count the G68 cost saving in the favour of the DSP speaker option.

I did not listen much in Type 1 (stereo digital speakers only) where upsampling might have been active, as reconfiguring the G91 and speakers was so frustrating and unrepeatable. Rather I used the DSP modes in Type 6 to switch from Trifield to Stereo.

Also the DSP5200 speakers were brand new, not sure if there is a break in benefit.

I am working on getting an N803D audition and will report back with findings here in a few weeks.
