Having TV’s on usually reduces enjoyment. Seriously though, you have to try this out for yourself. Dedicated lines are a significant upgrade if that is possible for your system. I was listening to my system last night, Christmas Eve, and the sound was exceptional. Assuming there would be lower noise on power lines coming into my home due to the holiday, it made me think I might need better filtering. The folks that use the PS Audio regenerators seem pretty happy with the results, and regen seems like the ultimate resolution.
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 wish I could tell you that any of these meters gave solid data on noise and perception. So much depends on the filtration in your gear as well. My basic guidelines are to create two zones of power conditioning. One is the clean zone on which your analog devices with nice power supplies run and another is the dirty zone for wall warts, TVs and PC's. The biggest mistake I see users make is to put noisy and dirty devices on the same outputs of a power conditioner. With few exceptions you just introduce noise after it's been removed. |
I didn't expect a definitive answer but you never know until you ask, right? I did find that my garage lighting is horrendously noisy. It's cheap, bright 100W total LED strip lighting with a whopping 1,300 mv noise at the source, and a good percentage of that showing up at my gear. So garage lights off. Reducing line noise from 70 mv to 50mv (tv off) is beneficial. 70 mv is where the strength bar starts flickering a second bar. 50 mv and below seems sonically ok for now.

Everyone's power situation is unique, some cleaner than others. Conditioners very in effectiveness, likely a high quality conditioner will make a significantly noticeable positive sonic difference.
