My problem with it is the fact that I just don't know if I can hear an extra $300+ in an amp. Lol my single 410 running off the old school q450.4 image dynamics after some tuning sounds amazing compared to my old threesome pro80's. For me, I'd have to have a back to back test on my boat and see if I could actually hear the difference.
(But I'm around jet engines most days without ear plugs walking around the ramps so I'd put money on me not being the best candidate for an audio quality judge! Lol) I've got a PPI 600.2 on the way to replace the ID 450, if nothing else just to clean up some wiring And make some room. But it'll be nice to hear those speakers on an amp that can put out the power they want!
