Power cords or power conditioner

I enjoy music and have tried power cords and power conditioners. 
 

I had a furman power distributor- perhaps more of a surge protector than conditioner. Then I tried Shunyata Venom NR10 power cables on my DAC/ network player and I perceived an impact on the lower frequencies being clearer and the reduction of ‘noise’. The volume would be at the same level but the space between notes was clearer.  
 
I put a power cord on my amps and the clarity on bass notes seemed a little bit better.

Replacing the furman with Shunyata venom resulted in a drop in the noise floor. Overall impact was detail in lower end - seemed like I added a subwoofer because of the immediacy of bass drums, detail clarity during peaks etc.

 Is my mind playing tricks and giving me confirmation bias - maybe  I like how it sounds and listen to more music  so there’s that  

My advice is experiment and listen to as many systems as you can  What’s the worse thing that can happen?

 I won't enter an opinion for the idea of power cables/conditioners. Instead, as probably has been stated, do all that you can physically with the listening environment first. I should take the advice that i give here. When reading such books as Jim Smiths 'Get better sound' there are many ideas that can be tried out for free, and if they work as prescribed you are ahead of the game before spending extra money on other attempts to improve your systems performance at large.

 Tweaks are fine, if you so desire, after the physics that can be dealt with are dealt with first. 

Both? 

@wheelndeal1099, if anything I’d get a half decent power conditioner with a good power cable simply to protect that $10,000 Luxman amplifier of yours. Some say you don’t need them. But what if the transmission lines or the pole pig outside your house gets struck by lightning? Chances are that’s not going to happen. But you never know. 
 

  I’m a disciple of the “everything in a systems matters” church of audiophilia. From the wall socket to your brain, every piece of gear, cables, and interconnects, can affect your music listening experience. If you don’t address the matter of having clean power and minimal RFI and EMI running through your system, then I guarantee you that you’ll always be wondering why your music playback setup doesn’t give you goosebumps with the songs that you enjoy the most. 
 

  This article gave me a good look at your Luxman CD/DAC. 

Luxman makes some really nice stuff! But before you go all crazy jumping down the power supply, conditioner, cable, rabbit hole, I suggest demoing a better DAC. To my ears I found the sound of Luxman DACs to be too polite. Very smooth and full bodied. Just not exciting.

I'm not technician to answer your about the power surge, can look at the pro who answering the surge from the YouTube video. hope it helps.
