Selecting a grab-bag of "THX" gear and hoping it all sounds great together as a 'team' is an interesting approach but one I'd deem aimed more at mid-fi, and folks who don't have the time or inclination to audition (or don't trust their ears if they do).
As for me, I'll stay clear of that general approach towards gear acquisition as I trust my ears over THX on the front label. My system has been a work in progress over thirty plus years. I'm not much into guessing/hoping (except jellybeans in a jar).
It is a bit of work, but in the end it's a personally tailored system you can enjoy.
