First & foremost, there is no substitute for critical listening auditions under controlled conditions, especially when you're spending upwards of $6,000 (US). Unfortunately, controlled conditions, other than bringing speakers to your home, will very likely be virtually impossible, given your rather unique pre-amp and large home sound room. I'm assuming you know the Rega Ania is a MC cart and the Exact is a MM? Quite different sound signatures. A previous poster is absolutely correct with regard to your preamp having significant influence over what your TT & cart will sound like; not to mention the size and acoustics of your home sound room.
Secondly, speakers are, arguably, the most subjective sonic experience in audiophilia. Relying upon the impressions of others in this regard is a lot like asking someone if they like Asparagus more than Fiddleheads. Everyone who responds is very likely listening to components quite different from yours, in sound rooms different from yours, as well.
Thirdly, you say bass "is the most important thing" to you. Keep in mind there are speakers that can reach very low frequencies but cannot reproduce them very accurately. They will sound boommie and muddy in the lowest frequencies. YOUR EARS will have to decide how accurate or faithful to a live performance you want bass response to be. Have you considered the idea of a quality subwoofer?
Finally, I'm not familiar with your amp or preamp. However, 25 watts into 8 ohms, even in Class A, doesn't seem like a lot of power for a sound room as large as yours. Do you listen mostly at low volumes?
I've spent about 1.5 hours of serious seat-time with the Revel Performa3 F208, powered by a McIntosh MA5300, in a sound room smaller than yours. Even though the MAC MA5300 is rated at 100 watts into 8 ohms, it's probably more like 130 watts. MAC tends to be very conservative with their ratings. Under those circumstances, despite their rated sensitivity, I felt the F208 needed more juice & power to sound their best.
I've also spent about an hour of serious seat-time with the two-way design Spendor A7, powered by a 60 watt NAD integrated whose model number I can't remember, in a sound room smaller than yours. I think the NAD may have been a class D design but I'm not sure of that. I liked the Spendor but, again, felt they would perform better with more power & current.
I've also spent around 1 hour of serious seat-time with the Dynaudio Evoke 30, powered by a MAC MC275 & MAC preamp, in a sound room about the same size as yours. These 2.5 way 4 ohm design speakers sounded very nice, to me, and very accurate but had limited low bass reach. The Evoke 50 are rated to go about 5 Hz lower and probably do that very accurately, as well. Four ohm design speakers, generally speaking, are going to need more current to make them sound their best. I've always found, over the years, Dynaudio speakers to be very accurate. I think this is one of their hallmarks. However, here again, some ears like this and some don't.
Under the circumstances you are juggling, I would recommend you read Herb Reichert's 2-1-18 review of your amp in Stereophile and pay particular attention to the speakers he used for that review. You may find you don't need to spend anywhere near $6,000 (US) to accomplish your aim and, with your vinyl collection and budget, contemplate an ultrasonic record cleaning machine for your impressive LP collection, if you haven't already.
Buono Fortuna, amico mio!
