System upgrade

Hi out there all true audiophiles. Been interested in sound quality in music for 5 decades now and of recent times, due to the extraordinary increase in costs, especially since Covid, affordability just seem to be drawing ever further away from me. I thought until recently I had my forever system - just because I want to spend monies on other things in life - unfortunately, I’ve come to the conclusion, I’ll probably never stop changing & tweeking 🤔😁. 
System is - Trigon Epilog Reference intergrated, mbl C31 cd player, mbl radialstrahler 120 and REL R 528 SE sub. Even though it’s a decent system, the Last 12 months has had me looking  for more musicality from it all, as I’m drifting more & more to classical stuff as age creeps on 😁. Still well into dance and all the modern electronic stuff as well & always had a love of base. I recently tried a preamp for the 1st time & that produced significant results, although it would have seen the bst part of 9k  of spends to find, & that is just too much under current circumstances. I’m currently having a curious look into electrocompaniet aw250 integrated or the same brand aw400 monos secondhand. So, was just wondering if anyone out there has ever had the Trigon Epilog ( can’t find any true reviews or forums on this amp ?? ) & what they may have moved to & for what reasons. Also, folks that have gone to electrocompaniet, & the pros & cons found with them. Im still on cd’s. It recently been sparked into both  vinyl & streamers, so I’m also V open minded to all advice & guidance. I feel I’ve opened up a great can of worms for myself 😩. Appreciation in advance for all advice - Paul 👍
