Turntable volume help

Hello. I recently made the dive into vinyl & having an issue. It seems I have crank my amp into the 90-100% range to get decent volume out of it. I got an old Pioneer PL-514 from a friend, had it professionally cleaned & set up & replaced the busted cartridge with a Shure M97xE. Sounded awesome the store. Brought it home, hooked it up to a Rega Fono Mini into my Jolida 502b, and it sounds awesome. Only issue is the volume thing. Is there something I am doing wrong? Perhaps my amp isn't powerful enough? Any assistance would be greatly appreciated as am I really loving my vinyl, I'd just like it louder! Thank you very much in advance!
