The SqueezeBox test as I read it says the degration is HUGE !! 4bits of attenution (Volume 20 is 24dB) drops to 75dB dynamic range. Nearly 4bits lost for 4bits of attenuation. It's practically behaving like a 16bit DAC, that the low 8 bits don't even exist !!! It's behaving like a 16.2bit DAC. If I did have a "Perfect" 16bit DAC. And attenuated 4bits. And there by lost every I attenuted by, I'd get 72dB dynamic range, right? SqueezeBox gets 75dB. You can't get much worse. I agree other DACs will do better. But people keep referencing this squeezebox test in defense as showing all is fine and it's showing it couldn't be much worse. -- 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=77725 _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/audiophiles
