How much dirt is too much dirt

in regards to power conditioning?  I’ve always found better sound when turning off the tv, I thought because of the distraction (mental thing). Recent purchase of an EMI meter (Trifield EM100) shows the tv with 15 - 20 mv added noise to a base of 25 to 50 mv line noise, time of day dependent.  I sit here, close my eyes, flip the tv on and off, and hear real music tv off, painfully disrupted audio joy, tv on.  Then contemplate noise figures.  Specifically a post where a claimed drop of 200 something to 78 mv made their day.  I’ve never seen posted what is an excellent, good or poor number.  Anyone?  My real question being, will a line conditioner lower my power line dirt enough to be worthwhile?

I have no idea quantitatively. I have been pursuing high end audio for fifty years and each step with cleaner power has instant benefits to the sound quality. So, hence good quality preamps, DACS, streamers... etc, weigh 40 lbs or more, most dedicated to power management. Really good equipment will have two boxes... for instance a preamp. Direct lines, power conditioners, high end power cord all contribute to better sound. 

I payed attention to specs on equipment for the first couple years and then gave up, because by and large you get misdirected by measuring a few variables as there are so many. Hence, I never started measuring power or distortion.
