However when you reduce the signal level, the noise floor doesn't change so your SNR becomes effectively worse. Less signal, same noise == less SNR. That's why a fixed analog attenuator set your maximum listening range is the cleanest way to go - it attenuates the signal and the noise together, meaning that the noise floor in your amplifier is the limiting factor (which it might be anyway, in which case you're right and all this is moot). > > It also cuts down on the number of boxes, cables and power sockets in > my system, which is always nice.... > I agree. It is also easier to set up and doesn't require buying or soldering together an attenuator. -- seanadams _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
