I've read here and there post on pa5 being able to drive certain speakers or not, not to go lower than 2 ohms and similar, so here is my case - and forgive me but I was never good at math and even if I rougly understand the notions it's still too technical for me to place down the numbers on the needed equation (which I see above) by myself.
I have Martin Logan SL3 vintage speakers (https://www.martinlogan.com/en/product/sl3) very well sounding but lacking bass strenght (no matter if near o far from front wall). In other forums it's debated wether this is their weakness or rather a consequence of lack of "juicy" amplification, with 89dB/2.83V/m but a low impedence dip of 1.5 ohms.
Currently they are fed by Advance Paris xa160 - spec. here https://productz.com/en/advance-acoustic-x-a160/p/mxrdp straight from a Topping d90se via xlr interconnets at 5.2V, never used higher than -30db attenuation for my ears health's sake.
Moving the xa160 to a second system would a Topping pa5 purchase an upgrade?
If not, would 2 combined pa5 (used as monoblock - if possible - or bi-amping woofer and electrostat separately) be?
I temporarily placed a sub for testing, but in true the room space doesn't allow it to remain, so subwoofer is not a feasible solution, altough it clearly worked well.
