Mechans,
I may not quite understand your post,"supposed" to prefer the SET purity. The degree of sound quality and purity ranges a lot within the SET amplifiers, just as for PP tube or SS amps(I sure would`nt say they all sound simillar either).The best sound in home systems I`ve heard were with SET amps,but there are some SET amps that I realize will sound rather less than good. Rolled off extremes is a stereotype that can easily be avoided with proper speaker matching(as is true for any amp type). When done right the purity and realism is remarkable.
