switch mode power supply = trash?

Hi folks, I would like to ask you a rather dumb question: could one of you explain to me what are the benefits/disadvantages of a switch mode power supply compared with a conventional (lineair) transformer based power supply? I mean not the usual benefits like smaller dimension, cheaper, etc., but with regard to sonics. Among the respectable manufacturers and amplifier designers there seems to be different opinions regarding SMPS. Some regard this kind of power supply technology as trash, while others don't. What is the definitive answer to the question SPMS = trash?

Probably like everything else, there is no 'definitive' answer. Poorly realized switching power supplies will be 'trash', well-realized ones will sound much better. So, for example, David Berning's amps use switching power supplies, and while some may not like the sound, I daresay no one would call the amps 'trash'.
BTW, I assume we're talking about the same thing, my 'switching power supply' is your 'switch mode power supply'.
