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 .

Good point edev- i have been using corner Bass busters  ,and 2x4 ft absorption 
Panels,and first reflection ,even overhead before your seating area for reflections 
With carpeting not so much hardwood ,for sure. Today's panels some even have artwork on them  under equipment I so acoustics , good Med price Still points $$
A bit pricy I use Herbies a lot .for Vacuum tubes essential, and his tall footers 
And vibration pucks.  These all add up and keep cables separated and off the carpet. Or floor.  Treating your cables the Best out there which Bass uses
Stabilant ,Stabilant-22  is cut with alcohol for tight areas, apply a 12year + 
Effectiveness if you are not touching .first clean with 99% isopropyl alcohol

Foam applicators Craig I like best big and small for tube pins the Stabilant 
Enhances all electrical conductivity,and protects, go to their sure Many awards .
The latest Cables and power products ,and very cost effective 
High Fidelity cables ,which used patented magnetic technologies ,even their entry level products produce very audible improvement .i rarely buy any new product without spending many hours first . My friend bought some and I know his system well ,the  AC plugin line conditioners are excellent ,True theirrca adapters just to sample in your rca sourse cable  or their cost effective .05 AC 
all under $500 the .05 under $200 and cumulative . Every piece of Audio you own 
has magnetic fields . Hifidelity cables patented technologies takes  these electrical fields and focus them dramatically lowering the noise floor.
