I use a Densen B100, a minimalist SS design which has been described as SET like mid-high with SS bass in reviews.
Roy uses and recommends EDGE amps ... also a minimalist SS design. Having seen an EDGE integrated with the lid off it looks almost exactly like my Densen inside .... big power supply a minimal signal path.
The europas are pretty revealing, so I would expect harsh SS designs would be a bad partner, and tubes could work very well.
In my opinion you need to budget for sub. I run my Europas with a REL strata crossed at 50Hz and it's a great combo. Without the sub the Europas would struggle on rock and orchestral music.
