Step me up from Paradigm Studio 20 v4 bookshelf, seriously.

I have been around here for a few years. Enjoying the game about once or twice a week. Yes I am hooked. Kind of sort of laid back on forums. Bought and sold a sizeable amount of equipment with one-hundred percent feedback. Probably a mid-fi guy. Best pair of speakers I have owned to me are Paradigms, namely Studio 60 v4 and current Studio 20 v4. Can anyone take me beyond these? Yes, a bit temperamental they are. Have never stepped up to, I guess Hi Fi speakers? Have tried Spendor 8se (too polite?), Paradigm Monitor 7 (not as good as Studio versions), Elac dbr62 (close to Paradigms but not as refined), Totem Rainmaker (maybe too small, not sure been a while back), Monitor Audio Silver 2 (kind of like Paradigms). Hooked on my Paradigm Studio 20 so far. Current system = Mid-Fi integrated (?) Rotel RA-1572, Bluesound Node 2i, Marantz SA-8004, Mhdt Orchid DAC (seriously love it), fair amount of decent cables. Like pop/rock music mainly. Integrated amps I have used: Rotel Rx-1052, Sim 340i DPX, Rotel RA-1572 (current), Musical Fidelity A3.5, NAD C368, Arcam.

Mostly into monitors/bookshelf due to room size, maybe front ported. Thinking of maybe some Spendor A1, Harbeth P3SR (or other models), Reference De Capo, Fritz?, Pro Ac?, B & W? No room treatments in my 14 by 18 room, as is fairly inert acoustically. I am an older retired audiophile (55-70). A bit of tinnitus, so nothing too bright. On Audiogon daily. Looking for some input/ideas. Lateral moves probable?

Any serious input welcome (maybe a bit of non-serious just for fun!). Love this hobby.

Thanks,

Jim
