Should an amp have a "personality"?


I currently have a SimAudio W-7 amp.  If there is a word to describe its sound, it would be NEUTRALITY precisely capitalized.  I mean it is neutral to a fault.  It's NOT warm, or bright, or analytical, or sweet, or anything that might be misconstrued as a personality.  It's just "IS".  It has nothing that would offend me but nothing that is endearing either.  I suppose some people may like this type of sound.  I also have another SimAudio Moon W-3 amp, and although it is neutral, but it has a distinct personality of being slightly forward, slightly upfront and ultimately more interesting to listen to.  

At this point, I am a bit disappointed what the W7 is not "FOR".  I want its sound to be FOR something be it slightly warm, or forward, or a touch bright or something that is a bit interesting even if it is a flaw.  It's like a politician who wouldn't say he's for something at the risk of offending his potential voters.  

PASS Labs amps are known to be a bit warm in the bass along with all their class A type of sound just as tube amps but they somehow make music sings.

Incorrect part was assuming that it might not have one. That is impossible, at least from my point of view.

That is nit-picking.  If you're right then there should not be a word "neutrality" in the English language since there is nothing in the universe that is absolutely "neutral".
I never use this word when it comes to sound. Anyway, the sound should be natural enough and engaging. Some of those German audiophiles and a few others in their quest for the 'neutral' sound get  the sound that is sterile and lacks many colors and nuances of the original. Colors not colorations.
I believe a system, as a whole, should be able to " show forth " the recordings, in such a way, that when you are in your listening seat ( the sweet spot ), you are hearing your favorite artists and musicians, performing at their " finest ", in their chosen acoustic space, and you,  are completely engulfed and entertained, in the experience. Enjoy ! MrD.

You just used the word "neutral".  
It is also possible that you might prefer tube amp. I do too, I don't have one because I would want a great one and that is big expenses.
