Better? No....More powerful yes....
Just because a change is made doesn’t mean something is wrong….I don’t see why the obsession with weight always comes up when I don’t really lift them anyway at gigs....I'd rather bring a little more quality & weight with me then playing out using computer speakers like I've seen some people do
I load my Rock & Roller Kart & into the gig I go 1 trip.
Our needs are very different for our gigging situations....so what I do & what others do are totally different & have needs as such....the Traynor K4 is a killer KB amp with super sound, flexibility & tubes to soften your sound if needed. ...Make no mistake sound wise it’s in a class that is hard to beat period.
I have sound gear for smaller gigs but for my big ones which are all dance orientated & have to pump the floor I just need a bit more in way of power & speaker size to cover the audience & room size, hence the upgrade in a nutshell. The Yorkville NX 750p’s should fit the bill nicely they make quality gear & during A/B’ing against many TOTL powered speakers they sound the best to my ears in many ways and should do the job admirably.
Stay well
Enjoy your music
