Quality PC: plug into wall socket or conditioner??


I have a Acoustic Zen Tsumani Plus power cable. I have used it almost exclusively with a preamp and now an integrated amp

My question is: Will quality "aftermarket" PC's work better plugged directly into a wall socket or a power line conditioner?? (I use an Audio Prism conditioner which is 20 years old)

I have heard pros/and cons over the years Would like some advice on this issue. All comments welcomed!!! Jimbo

Thanks to all who have responded so far. Trial and error seems the way to go and makes sense. I just don't know where you guys find the time to run these trials

BTW, Several months, I ran a trial trying to determine which speaker cable sounded better. I play the Who's (remastered) track "Won't Get Fooled Again" six time in a row. After the sixth play, my upstairs neighbor knocked on my door and ask me if I want to see his shotgun and hunting knife collection. Hmmmm!???

TO ELIZABETH....I THINK IT IS TIME TO BURY THE HATCHETS. YOU REALLY OFFER A LOT OF HELPFUL ADVICE AND INFORMATION, AND ARE GENEROUS WITH YOUR TIME. I WAS OUT OF LINE AND OUT OF CHARACTER. THANK YOU FOR YOUR SUGGESTIONS

Would not be without my Power Plant. AC line is full of garbage which causes my music to sound grainy and unfocused. A good PC is must whether you plug directly into the wall or a conditioner.
To me it depends on the equipment and the location of where you live. Audiophiles in my area have long decried the quality of the electricity in my neighborhood. So my sources get plugged into an isolation transformer and/or power conditioners with their aftermarket power cords. My amps that have Pangea AC9 power cords get plugged right into the wall but I changed out my outlets to Albert Porter Hubbell based outlets.
Well, I could stick my finger in the electrical socket to judge the quality of the AC, measured by how far it propels me across the room

The quality of electricity in my neighborhood seems OK, except occasionally when the lights dim for about a second. I live in a high-rise building that has 329 units. Everybody has got a washer dryer combo. When I first moved in, I picked up RF interference through the speakers when I played LP's. Mainly, FM broadcasting. The power line conditioner eliminated that almost completely.

Though, I have to agree with Sonic Genius, there is a lot of garbage that comes through the AC. Once I picked up a Coast Guard cutter transmission off of Oahu....Fortunately, it was not classified, but only about the beer supply on board, and shark repellant

I will give the wall socket a shot.
