I am with @jperry on the ProAcs. You should definitely listen to the new ProAcs. Not sure about your budget, but in the same budget range, I think you might choose the ProAcs over ATCs. I auditioned both when I visited the AXPONA 2017 and chose the ProAcs. Do listen to both - since your listening preference is your own and only you can decide which one you like. Good luck!
Speaker questions ProAc, Harbeth, ATC
Would like the forum's view on a potential speaker upgrade. I listen to ProAc Response 2.5 speakers which I purchased nearly 30 years ago. They have been wonderful. I also have a REL T9x subwoofer. Since the speakers are so old, I have been thinking of looking to upgrade. The options I have on my list are new ProAcs, ATC and Harbeth. I would be prepared to buy used. I am looking for a similar sound to the ProAcs but maybe with a firmer bass. I listen at reasonable levels and my tastes are classic rock and jazz. I find the ProAcs are great with jazz. My room is not dedicated to sound only and is 15 ft x 20 ft. Thank you for suggestions.
