Audio cables ,and power cords the most forgotton- part of an Audio system.


I have been in Audio for over 35 years and owned and operated a  Audio store as well as buy just from the A list ,which does not guarantee system synergy.
I have tried   inexpensive cables like blue jeans  that is fine for a entry level system. 
If you have electronics $5k and up and 5 figure Loudspeakers then to get ultimate resolution 
You have to spend some money's on cables.my last cables 2pr interconnects  and a pr of 6ft Speaker cables 
I had, Silnotes, Analysis plus  even more expensive Synergistic research.  Decent but not the realism I was after.
To get to that last5-  10% + in fine detail and resolution you have to spend. I was stubborn but really 25% for example.Of your total cost is not that much. When you see just how much refinement and fidelity 
You may be missing .My brother brought over his Verastarr power cord over to try on my digital 
Which is most sensitive,  I had a $600 Kimber power cord, his grand illusion cord made the music so much more real,there are other very good cables but these are one of the best I have ever heard without breaking the bank. . Is that worth over $1k ?  I did the same with interconnects and speaker cables 
I spent $6k  and still have s few power cords to go. One thing my system as a whole is a minimum of 10% better. And  a you are there on any decent recording.   Fine tuning with Duelund capacitors
Bypass and coupling caps are next and final step in tweaking the system and a bit over priced. and these may be equal to or better  in added tonal balance and depth. 
This just proves having the best speakers or electronics is only half the battle.
You are only as strong as your weakest link .

One thing j do know, and better then half the people do not. 
Having been directly involved in modding my equipment.and owning a Audio store I speak from facts. Less then 25% of the cost actually goes into the cost of mtg,
Everything else is overhead and at least 45% dealer markup. Meaning the internal parts are at best average ,until you start spending over $10k it is just a fact if life 
In electronics thst is why Modwrigh t Audio,red wine and others have been so successfully better parts quality in key locations .I have 20 years of this my whole system us built with synergy ,not $$ in mind ,thst being said 
Quality capacitors,resistors, all cost$$ a that too goes for wiring ,controls , 
Marana is not what Marantz once was .hand built Vacuum tube made in USA.
Even they have several 3-4 price quality groupings  like Copper chassis these bits and more are in the $$4k and up grouping. You get what you pay for ,usually.
I’m getting a lot of joy from cables made by Sablon. Started with their USB cable and that was so good I had to try the Sablon IC’s. Outstanding again. So next I needed to try the Sablon Power cables. Plugged it into my server and the increase in performance was stunning. All the cables helped to produce a much more open and natural sound, which is denser and visceral with more detail. Highly recommended.
Toe tap audio  why don't you say how much the Sablon  power cord was $$
That would give others an idea of how cost effective it would be  for them.
Toe tap audio,  Sablon are a very respectable  cable and were mentioned in 6moons online Magazine in 2015  the Verastarr grand illusion cables review,
Not quite as complete as the Verastarr cable, but still very good.
That is saying alot .
If your into the hobby, and want to make the best of your system then you have to consider aftermarket options. 

I at first hesitated on pulling the trigger on cable and then changed course and don’t regret it, despite a ton of cash spent. 

All things add up to get to the plus side of the systems grade and you can start with one, borrow, try, buy whatever. 

Last, while power is important so is the room treatment and isolation. 

Always learn, choose and listen.

Happy New Year!
