Getting a negative result from a blind A/B comparison is the "Road to Damascus" moment that opens the door to rational thinking for many audiophiles. It happened to me when comparing DACs about 5 years ago.
In this case, you appear to have demonstrated that there is no discernable audible difference between the stock SMPS and a linear supply, in the context of your system. As you say, it's possible that your system isn't revealing enough. But there are other explanations. For example, Sean Adams has in the past explained why changing the external PS shouldn't make any difference - seems reasonably plausible that he might know what he's talking about. FWIW, my hypothesis is that the reason the SMPS sounds worse in some people's systems is not because of the actual supply to the Squeezebox, but because it sprays all sorts of nasty RFI around the place, which could affect the analogue circuitry in other components. Some systems will be more vulnerable to this than others. But remember this is just a hypothesis to try and fit various people's findings. -- cliveb Performers -> dozens of mixers and effects -> clipped/hypercompressed mastering -> you think a few extra ps of jitter matters? ------------------------------------------------------------------------ cliveb's Profile: http://forums.slimdevices.com/member.php?userid=348 View this thread: http://forums.slimdevices.com/showthread.php?t=31758 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
