Currently I have a Aperion 533pt system that I have had for 10 yrs. The avr I use is the Arcam 390. My listening habits are 75% Movies 25% Music. 90% of my media comes thru a nas using Kodi. 10% is cd thru a PlayStation. I really like my current setup. The only things I feel missing is music listening specifically hard rock doesn't hit as hard as my old cerwin vega at-15 or the infinity sm-152's specifically really loud granted my ability to listen like this is only when the wifes out. My current room setup is not media room but instead my living room that is attached to very open concept kitchen.
The question is what is best way to improve my current system.
1) upgrade the LCR to maybe Aperion versus grands 6t, or Polk R700s, I will likely purchased used under $2500
Or
2) adding amp, thinking either the Emotiva xpa or monolith
Your advise would be very much appreciated
