Audioquest Power Cords

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

...and here we go again ! This time, Blue Jean cables has all the answers and are the best.    

Hi I was just giving an example of  any quality cable manufacturer will work fine 

MonoPrice, Amazon, some of the entry levels types from any brand will work as long as the cables in question follow design guidelines and not ridiculous statements like our cables reduced noise and distortion which is nonsense 

THERE WAS A STATEMENT YEARS AGO “An Educated Customer is our best Customer “

Any AudioPhile that believes in purchasing cables that are extremely expensive and have pseudoscience with Snake Oil Marketing is welcome to enjoy there purchase as in there mind they feel more secure believing all the hype

OP was asking about the DBS 72v… so stick with the topic of the thread.

Leave it unplugged for a day to see if the result still the same or it got worsen?

I saw a review on Audioholics where he found the DBS added capacitance to the circuit, so it is doing something measurable. While most would not want to add capacitance, it could, in certain cases, alter the frequency response. In theory at least.
