You definitely get better electronics.  Mine is a NS-WAV which is on the low end of the spectrum, but it feels and sounds like a big step up from the Shar Plug 'N Play I used before.

But, it's a lot like Electric guitars.  Yup, you can get a very playable electric guitar for $300.   You move up to $800 and you are going to see and feel the difference.  Now, going to $2000 and up, those differences are going to be a whole lot smaller.

It's like that for things like bicycles too.   There is a huge difference between a $100 discount store bicycle and a $300 bicycle.  Go up to an $800 bicycle and still more of a difference.  But, between an $800 to $3000 bicycle, the differences are much smaller and you pay a lot more for just a little more.

I think it also depends on perspective/interest/desire.  For example, are you a violinist, or and ELECTRIC violinist?   If your main goal and desire is electric, then those small nuances become much more important, and to get the most out of an electric, there are some differences in playing style that come in to play.

If violin were my primary instrument, I would probably already have a Mark Wood Viper.  :D.  But, it is not my primary instrument, and for me that sweet spot of the NS WAV range (or maybe a wood stingray) is perfect.  Where on guitar, you can probably guess how often I pick up one of my cheaper or even mid ranged guitars compared to my Les Paul.  Which amusingly enough, is cheap compared to acoustic violin standards, and something I often point out to other guitarists when they complain about prices:  Be glad you don't play an orchestral instrument.
