Chris, further to my last post, system synergy is the thing we all look for, that is not only how all the equipment gels together, but also how it interacts with the room. There are many video's on YouTube on this subject, see John Darko's channel for one example. I have tamed some bass bloating and trebel / mid harshness buy using acoustic panels, not many as the cost and physical space they can take up would also spoil my lounge layout. In the end it's my living room as well not a recording studio, but all the same it did help. GIK acoustics in UK do have some helpfull video's on their website on room acoustics out of interest.
My 102/180 combo was a bit shouty, using a HiCap which you have helps, the 82 is definetly an improvement. Tweeking cables, going to a Supercap and 250, changing to WH Pheonix boards in the 250 all changed the way the system sounded, for the good to me anyway, mostly eliminating the similance on the highs at higher volumes being one benefit. I have also gained the improvements in soundstage, seperation dynamics, bass etc, you can keep chasing down these things and spend a lot doing to, I have tried to keep a sensible lid on this. I am very pleased with my system now, found a happy spot, any other changes will cost more than I want to spend at the moment.
Others would say change the amps to something different, what you get is a different sound, it's all horses for courses, some bits may be better so not so, it's the sound you like that counts, thats why we are all different and why there are many different equipment manufacturers out there and not just one.
One thing I have found in life is nothing is perfect, like Roog says above, speakers and room interactions do play a significant part in what you hear, sounds obvious, but that maybe a route persuing before changing amps. For me I love the Naim sound, always have, I've owned other amps in the past and listen to friends equipment but always come back to what i like. The olive gear is good VFM for me anyway.
It's a hobby for me, I just love music and am happy to listen to it in my car, through my Alexa, on my Sonos etc, yes the HiFi is better SQ but it's enjoying the music that counts as well as long as it is not grating.
