Some of you may remember my very old "Canton - taken the plunge" thread back in 2013 as I was setting up our system at the new house. Long story short, still run them and still very pleased with them but feel some things could be improved. But as with everything, there are others who know better so the best place to ask? Here! 
So here we go.... currently run a 7.2.4 (a bit unsure how my system is actually named as to me its a 9.2 system, but I have no idea!?) system, as follows:
AV Receiver: Onkyo TX-RZ3100 (previously had a TX-RX5010) - a bit unsure of the power this one gives....
Fronts: Canton Vento 890.2 DC (bi-wired with 2-to-4 cables) - Nom./Music Power handling 180/340W 20-40kHz
Center: Canton Vento 858.2 - 120/200W 26-40kHz
Front Heights: Canton Vento 820.2 - 60/100W 32-40kHz
Side and Rear Surrounds: Canton Vento 810.2 (x4) 60/100W 40-40kHz
Subs: Canton SUB 1500R x2 - Active, Bassreflex, 2x 12.2" drivers (one is passive), 18-200Hz
This in turn is hooked up with a Sony KD759005 (75", curved), Apple TV 4K, PS4 etc etc together with "proper" cables etc and while I am quite pleased with the system, I do feel that some things could be improved and one of the things I am considering is a Power Amp to drive the fronts and to help off-load the AVR a bit as it gets seriously hot sometimes. Not sure if I should also hook up the Center to a Power Amp?
I might also change one of the subs to an SVS as although nothing wrong per se with the subs I have, but I wouldn't mind going a bit deeper/lower.
Perhaps there are other areas that would benefit from an upgrade that I simply overlook/don't know about?
Mainly use the system for movies from the Apple Tv unit but also from Blu-Ray as well as Music using "all channel audio". Usage about 70% towards Music and yes, I do like it (very) loud at times.
Don't mind spending a bit to get quality stuff so open for every suggestion
Thank You in advance!
