@mofojo:
As our member soix would ask at this point, What sort of sonic signature is pleasing to you? What are you looking to hear that you’re not yet hearing?
If you can answer that question, and if the inference about you liking the speakers is correct, then some other amplification might be the path for upgrade.
+1
I've seen comments on the forum asserting that upgrading amplification is not a way to gain major improvements but having just experienced the biggest improvement ever in my system after upgrading my integrated, I can't agree. It's become clear that my speakers are much better than I ever realized. If you like your speakers, I'd also suggest you seriously consider upgrading your amp as one possible path forward.
