For sure, excessive digital attenuation in the TP does sacrifice a bit of S/N ratio. But let's keep things in perspective. If you have appropriate passive attenuation installed such that the TP's volume control is up around 90% or so for critical listening, then using lots of digital attenuation for casual listening isn't going to be a problem - the noise floor remains below the threshold of hearing. Running lots of digital attenuation is only a problem if you follow it with lots of analogue gain.

Do yourself a favor and try a setup without > preamp and you will know why I do NOT want to go back. I'm with you, Michel - I run my TP directly to power amps with XLR. I would never contemplate inserting an active preamp in the signal chain. But as others have pointed out, you can use passive attenuation without loss of quality. (My setup has 13dB passive attenuation). But let's get back to Michel's original problem: conveniently running headphones from the TP. A couple of possibilities occur to me: 1. Wasn't there an older firmware release where it was possible to specify variable analogue output while keeping the digital output fixed at 100%? I believe this facility was sacrificed to make room for some later feature (digital FX loop, perhaps?) Maybe Michel could track down this older firmware and use a headphone amp with SPDIF input. This isn't practical if he wants to use Squeezebox Network (or whatever it's called this week), of course. 2. It would be fairly easy to build a passive switchbox that takes whatever TP outputs are used, feeds them to the appropriate devices (ie. power amps, headphone amp) and has switches to connect/disconnect as required. -- cliveb Transporter -> ATC SCM100A ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=80088 _______________________________________________ discuss mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/discuss
