New speakers ?

[Vinceb]

Hi I currently have mission 753s as my front speakers in my home cinema set up , mission centre & rears & just purchased a Q Acoustics sub , I’m considering a denon avr x2700 , to replace my old 3802 , is it time to replace the 753s, they still work fine but the room is only 3m x 3.2 m & I was considering some stand mounted replacements , or keep them & replace the old 77c centre & 77 rears ?
