That's how my dad feels, so I gave him one of these and he says it's the best thing I've ever given him (not counting his grandkids):

The X2
D model so he can use his own DAC. He feeds it via USB from his WiiM Ultra. The X2D then feeds a Luxsin X9 DAC/preamp via coaxial S/PDIF that handles bass management and volume control for his SVS SB-3000 subwoofer and a pair of Topping B200 monoblocs that drive a pair of Magnepan LRS+. He has a fully treated, dedicated listening room. It sounds amazing. The Anti-Mode algorithm corrects both, frequency response and phase (unlike RoomFit, which only does frequency response, or DIRAC Live, which does frequency response, phase, and impulse).
He couldn't be bothered one bit with the faff that is WiiM RoomFit, or DIRAC Live. The Anti-Mode is as simple and easy as it gets, and he even enjoys the built-in tone control.
