Right, and even fancy parametric eqs are just combinations of RLC nets. > I'm happy to accept that, but I'm asking why don't all the other elements > in the audio chain do just as much damage to the relative phases as an > equalizer?

That is why there is a whole branch of audiophiles who are into single speaker systems, i.e. http://www.lowtherloudspeakers.co.uk/ And I believe that is why quads and electrostatics sound so good to my ears -- no crossover. One of the old time design points was for a preamp to be within a db or so from 5hz to 100kHz, with the idea that it would not add any new phase inflection points. And one of the few plausible justifications for mega dollar interconnects and speaker cables is all cabling is nothing more than a RLC network. -- Pat http://www.pfarrell.com/music/slimserver/slimsoftware.html _______________________________________________ audiophiles mailing list audiophiles@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/audiophiles
