How does my MF A308 compare to modern integrated amps in the $3000-$6000 range?


Are more recent amps in the $3000-$6000 range superior enough to warrant an upgrade?

Thanks. I’m happy with the sq, but I have no frame of reference regarding other options.
I'm with @jjss49 

Mostly what you'll find out there will only be different, not unequivocally better or worse.  Unless there's a particular aspect of your sound that's lacking and needs addressed (and is easily attributable to amplification), I wouldn't start a new search.
