Hi I am a retired ABC TV Video/Audio engineer of 34 years, AudioQuest as a Cable
Manufacturer has brilliant marketing department with descriptions of there products
and how they reduce noise and distortions
1-The DBS 72 VDC system is just a marketing ploy, SNAKE OIL
2-Power Cords…only need to be low enough gauge for the equipment connected to 12-10awg is fine..SNAKE OIL not pretty and come in $100 mahogany case LOL
3-HDMI 2.1 cable that are certified will work up to 15ft…no difference from a $12 cable to over $1,000 cable spending more is just foolish waste of money no difference
4-USB Cable as long as the USB Cable used has certified specifications a $10-25
cable will work fine…using a USB over this amount is again waste of money…SNAKE OIL marketing ploy
5-75 ohm Coaxial Digital Cable a $5 cable will work jus fine hear too…USE CINNAMON FOR BREAKFAST PANCAKES not for a cable $100 just silly
6-TOSLINK CABLE (OPTICAL AUDIO) S/PDIF again a properly designed cable
at costing $10-15 with work just fine…spending more from Manufacturers that state
there TOSLINK is superior is totally misleading…SNAKE OIL PLOY
7-RCA (single ended connection) any well designed low capacitance cable will work fine here also…most of the differences heard changing cables has to do with metal used (copper or silver) never used silver copper clad types and impedance of
the cable…high capacitance will have reduced high frequency energy
7a-Balanced XLR Cables low capacitance well made copper cable will work
here also…putting a 72vdc on a $5000 cable is just again brilliant marketing ploy
SNAKE OIL
8-LOUDSPEAKER CABLES low resistance low inductance is required for a proper
working design how it is made using braided or flat on top is good practice
9-POWER CONDITIONERS and REGENERATORS are not needed waste of money most of these don’t even address the power line issues just look fancy
To make a proper AC Filter would require a large inductor or transformer
along with capacitors to start the filtering at 120hz not 5khz like some others
that do absolutely nothing to improve the final output at the amp to loudspeakers output
AUDIOQUEST and many other cable manufacturers are making MILLIONS of Dollars of the uneducated AudioPhiles…selling unproven claims that science can prove that are marketing ploys and thus considered SNAKE OIL DOES NOT WORK
IF SOME NEEDS ANY TYPE OF CABLE JUST GO TO BLUE JEANS CABLE and purchase the cable for your needs no reason to purchase a cable that cost more than Armani Suit
AUDIOPHILES spend your hard earned dollars on quality equipment not SNAKE OIL
