Should I Upgrade from an Edge G8 amp to the Edge NL-12 amp??


I have an Edge system now with an Edge G2 preamp and Edge G8 amp. I like it, it’s detailed & resolving, but just not in love with it. It doesn’t seem to have the punch in the speakers I thought the pair would produce. Maybe it’s cabling or source, or speakers. I was considering a power upgrade to the Edge NL-12 to improve on it. Any thoughts pro or con? Or could I do better going in a different direction. I'm open to all suggestions.

Thanks.


EDIT: This is for a secondary system in a 15x22’ room.

I owned the G2 and G8 and upgraded to the NL 12.1 and Sig 1.1 SE pre. Very nice and a significant upgrade. Running with B&W 800D and lots of bass impact battery or wall power, Room has proved the biggest issue, particularly with the bass.

Yes... I am upgrading to the Maker Audio NL 14+ mono amps.  Maker Audio is formerly Edge Audio, with the same lineage and designer, Tom Maker. Now looking for a suitable preamp (suggestions welcomed) for these mono blocks amps.
