Yes I have. SPDIF volume out of G68 to DSP speakers is fixed. One issue though is Speaker Calibration is done digitally. If I reduce volume by calibration then SPDIF goes down. If I reduce by Master Volume it's fixed on SPDIF. I agree a lot of us Meridian owners would love the gory details. A lot is from some folks more knowledgable than I. Some is from older data sheets. Some is from folks talking to folks at Meridian. Some on our forum. The "DSP Speaker" doesn't change anything in this regard. Meridian does not reinvent the wheel when they discover something. Like their new Apodizing Filters are in speakers and preamps, their upsampling is in speakers and preamps, their volume control is in speakers and preamps. It's repackaging the same technologies. Think of the G95 you looked at as just being inside the speaker. DAC, Preamp and Amp all on one box. Like I said ealier biggest difference in DSP Speaker are they do the crossovers digitally. You can actually hear signature clicks at certain points of adjusting volume on both Analog setups and DSP Setups. If it were pure digital attenuation. You would see a similar reduction in dynamic range when turning level down via G68 volume knob vs turning it down on Transporter knob measuring the same DAC at the same levels on the same sound card. Very different results. That's because transporter is JUST digital attenution, which we know sucks. -- mswlogo XP > Cat5 > Transporter/DuetController > SPDIF > Meridian G68 > DSP6000, DSP5500HC, DSP5000 XP > Cat5 > SB3 > SPDIF > Meridian DSP5000 XP > Cat5 > DuetReceiver > SPDIF > Meridian G91 > DSP5000 'My Transporter Setup' (http://forums.slimdevices.com/showpost.php?p=350741&postcount=45) 'Hitch Hikers Guide to Meridian' (http://www.meridianunplugged.com) ------------------------------------------------------------------------ mswlogo's Profile: http://forums.slimdevices.com/member.php?userid=9090 View this thread: http://forums.slimdevices.com/showthread.php?t=78477 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/audiophiles
