I think the list is short if you’re thinking Snaxo/Naxo!
Linn ~ Briks , ???..
Naim ~ DBL, NBL, SL2, SBL, …
And of course, DB ran Active Briks before Naim’s Ovators line.
And the aforementioned Kudos line.
If money is not an issue, maybe you can find a pair of 800s somewhere, or 20K for some Titans!
Otherwise, keep your SBLs if you like their character! If not, who knows, you might get lucky and find a late SN. pair of Isobariks/Briks, or NBLs.
SL2s might catch your fancy, personally I think the Snaxo is at its best in 362 mode vs 242.
Three way speaker vs Two way speaker!
After all we are negating the XO from the speaker and implementing it betwixt the pre amp & amp.
Its hard to explain, but an active system just seems to breath easier. The music flows effortlessly, and when you need the signal, POW!!!
But what do I know, just saying!
Being an active fan I’ve done Linn’s active show:
LP 12/Ghinki > Ikiem > Linn XO with bingo card >
Dirrack PS > 3 x LK 280s > Briks!
The only gear from the above list that is incorporated within my system presently, is da Briks!
CDX2 > 282 > HCDR > 3 x 250.2s > Fraimlite!
Enjoy Your Music, The Why!
The How will be just fine.
