Hello, another topic which a bit bothers me as I am not so topology techie-profi guys like many of you ( rather a good listener ) from my experience, amps which are equipped with MOS-FET transistors actually sound different. More mature with emphasis on airy treble. In general MosFet amps are more expensive. Is it just a matter of sound preference or indeed MOSFET amps sound better in any case compared to "normal" transistor amps. I have heard some MOSFET amps and need to say they really sound good. But also I heard many good sounding non MOSFET ones ( bipolar transistor based ) Is it just a "pluses and minuses" of both ? Or indeed MOSFETs are best way to go for transistor amps ?
