I just read specs on your speakers and amp. I recently upgraded from a pair of Focal Chorus 836V speakers to the 1028be which is driven by a Marantz Pm 11S3 integrated and I love the combination. While specs are not a substitute for listening to a system, your speakers are remakably similar specs to the 1028 and your amp puts out 150w and doubles in output ( like my Marantz) to deal with the 100ohm dip Focals tend to exhibit so I imagine the upgrades would need to be very dramatic ( and expensive) to make a significant sonic improvement.
If money is burning a hole in your pocket perhaps consider these alternatives:
room treatment - as mentioned above most people ( including me) spend far too littl attention to this.
GAIA isolation feet. These are on my Christmas wish list as an easily reversible tweak that seems to get nothing but positive reviews.
A second subwoofer ?
Merry Christmas
