Level 3.3 USB Cable By AntiCables


The AntiCables 3.3 USB is the company’s reference USB cable. The 3.3 is a particularly excellent choice to inject a bit of analog goodness into a digital system with a bit too much of a forward, high-frequency-focused, and etched character. All cables are cryo-treated.


Product Description

With the 3.3 USB, AntiCables applied everything they learned during the 2-year development cycle of the Level 3.1 USB cable. A new wire topology better holds the proper characteristic impedance from end to end. The results are 100% positive.

The former Level 3.1 USB cable was so good there was’t much room for improvement but they also doubled the gauge of the +5V wire. Doubling in size helps sonically with the occasional DAC that uses the 5 volts for power and it’s less likely to get kinked.


  • Standard USB type-A to USB type-B plugs
  • ACElectrum™ Silver/Gold alloy signal wire
  • The 5-volt wire is separate from the shielded Data pair
  • Outperforms the highly acclaimed Light Harmonics “Lightspeed USB Cable” at 1/5 of the price and the $2,000 Synergistic Research USB cable at 1/8th of the price
  • Made in the USA (one at a time in Lake Elmo MN)


Design & Sound

The unique design of the 3.3 USB cable will bring you better-sounding music than competitive cables costing many times more. This cable has the ability to make your system sound more like real music and less like a digital source than cables priced as high as in the $1,000 to $2,000 range.

The USB 2 Standard:

The USB 2 standard calls for a 5-volt DC power connection. This is so the “Host” (your computer) has the ability to power or charge whatever device the USB cord plugs into. This feature is extremely useful for devices such as a USB Flash Drive, so an extra power adapter is not necessary. Yet the 5-volt DC connection is problematic for what needs to be achieved for the best sound.

The Key to Good Digital Sound:

Jitter-free perfect timing is the Holy Grail of digital audio and a huge reason why digital components and cables can sound so different. A computer’s 5-volt power supply is filled with noise. Within a typical USB cord, this noisy 5-volt DC supply signal passes through a wire that runs along the entire length of the cord. The computer’s noise is induced into the data wires which introduces timing errors that jitter the streaming digital signal, causing digital distortion. Jittered digital data is what causes the music to sound hard and flat. It causes a loss of pitch definition, a loss of dynamics, a loss of sound stage depth. Jitter blurs the bass and makes cymbals sound like spray cans. Timing errors are our enemy.

Dealing with the Noisy Computer Power:

Many USB cables forgo a 5-volt power wire but many powered DACs still require the 5-volt wire to operate. Either the USB chipset is running on the computer’s 5v power (which is not good for sonic performance), or the circuitry looks for the 5 volts just to confirm the USB connection has been made. Because of this, a very small 5-volt wire runs external to the shielded data pair and it’s far enough away to cause no sonic impact.

Other Design Considerations:

Like all other AntiCables products, only the necessary parts and materials are used. The cord is free of thick plastic jacketing to eliminate Dielectric Effect Distortion. The data pair conductors use the excellent sounding AntiCables ACElectrum™ Silver/Gold alloy wire which holds the ideal 90 Ohm Characteristic Impedance for USB data. The ACElectrum™ wire provides the ideal extension and resolution of solid Silver wire, but without the bright and forwardness that always comes with pure Silver. Highs are highly detailed yet remain soft like real music.


Reviewer Dave Clark of Positive Feedback said:

“The ANTICABLES (USB Cord) is open and dynamic, clean and articulate. The music comes through with a wonderful sense of flow. It does tend to be a bit more robust and perhaps darker through the midrange than others here in house, though I feel that might be related more to the bass presentation being big and ballsy (or perhaps the use of gold).”

You get all the little things—air and ambiance—and lots of the bigger things, like atmosphere and space. Lots of separation and there thereness. The high end is all there though perhaps the overall presentation is a wee bit more forward in relation to the speakers when compared to other USB cables here in house… though I guess one could argue that perhaps those are a wee bit laid-back? Even so, the ANTICABLES USB was never fatiguing or over the top. Stellar soundstage too.”

“The ANTICABLES USB is highly recommended. Sweet indeed… I found myself listening more to the music than what the cable was doing to the music. Which is what it is all about anyways.”


A few Real Testimonials:

Scott Morgan, Portugal
“Thanks for the awesome “Christmas present”! I spent most of the night listening to my stereo with my wife and it was magic… really magic! I’ve spent a lot of money buying expensive components, cables and sound treatments for the listening room. Who knew that by just replacing a USB chord the whole room would come to life. The soundstage is bigger, the music is more focused and airy. Like I said , Magic!”

“You made an awesome product. We hope you have a merry Christmas and a happy New Year. Sincerely,”

Roger Chiu, TX
“Thank you so much! Your (Level 3.1 USB) cables are awesome! My friends Sam and Jason also love your products, and we will continue to spread the word for you. I am currently running your Level 3.1 USB, Level 6.2 ICs, and level 3 speaker Wires. Excellent stuff! Thanks & Best Regards,”

Jason Jue, TX
“Roger Chiu is my cousin and he recently purchased a USB cable from you with great price. We tried it on my system and it sounded fantastic! Roger is a big fan of yours and he has got me and my friend Sam on hook with your products.”

“I recently bought a pair of level 3 speaker cables from you to upgrade my existing level 1 speaker cables. We all use your interconnects for our systems. I’m looking to buy a USB cable… Thanks!”

Orkunt Dalgic, NY
“The Level 5.2 RCA interconnects I bought from you, as well as the new Level 3.1 USB-cable, I am really happy about. They make everything sound so open and natural sounding. I also detected a substantial improvement in the bass response.”

Doug McAlpine, UK
“Just wanted to pass on that these are by far the best cables I’ve ever used (my 1st order was for a Level 3.1 USB cord and pair of Level 3 speaker wires), and have now just ordered the Level 4.1 Shadow XLR interconnects and another USB cord… They smoked some much more pricier cables which I will be promptly selling.”

Alex Garkusha, NY
“I compared it (the Level 3.1 Reference USB cord), against my other cable which is Transparent Premium USB cable ($600).”

“Your cable outshined the $600 one on jazz and classical repertoire, especially when the loudness is set higher. Your cable consistently delivered better and wider soundstage, and absolutely won in lower frequencies, especially with faster notes with bass instruments, and more natural rendering of the drums.”

“Your cable is neutral, while Transparent adds some sweetness, which some people prefer, but I don’t.”

“Your cable renders approximately the same amount of details, but your cables’s presentation is still smooth, while the Transparent’s details are a tad harsh.”

“Overall, it’s unforgettable sound it creates. Thanks,”

Don Harn, GA
“Right out, it has much more sparkle and overall clarity (Level 3.1 USB cord). Voices are excellent. My wife is concerned with the low end, which I feel is there, but now competes with the rest of the musical range.”

Mike Tobin, NH
“I received my USB A/B cable yesterday. Wow it was fantastic right out of the gate. My question is does this type of cable require a break in period such as the RCA and speaker cables etc..etc.. In other words will this cable sound better after 100+ hours?”

“Nice job as mentioned above it sounded great right out of the box! Thanks!”

Mike Tobin, NH
“Excellent news it’s hard to imagine this cable getting better, needless to say I’m looking forward to it. The low end is incredible. Lots of ambiance as well; what I mean is back ground sounds on different recordings that I had not noticed before.”

“BTW FLAC streaming on TIDAL is fantastic Hi-Fi sound.”

Dan Rubin, San Francisco Audiophile Society
“I retrieved the Level 3.1 USB cable with 5V wire from Leslie after our event last Saturday and have been using it with my Luxman DA-06 this week. I am VERY pleased with it. We used it with all of our DACs at the audio club event, to keep a level playing field. Regards,”
