Dr Anwar Ali, the audiophile and chief tweaker who owns AA Audio, has done Malaysia proud by being the second Malaysian hi-fi designer to have a product named as a Most Wanted item by an international publication.
Stereo Times has named his AA Audio Sig XT (Extreme) USB Cable Mk 2 as one of 2025’s Most Wanted components. Stereo Times said:
AA Audio Sig XT (Extreme) USB Cable – MK2 (1 meter: USD $1,125): AA Audio is a one-person shop based in Malaysia, run by Dr. Anwar Ali. For those of you with USB sources who have tried all ranges of USB cables, this one is undoubtedly worth a listen. I’ve had the opportunity to compare this cable with other cables costing multiples more, and this cable in my system provides a wonderfully low noise floor, extreme dynamic range, along with beautiful timbral expression. It is my endgame USB cable for the foreseeable future. The soundstage it produces is just glorious, and scales wonderfully with the quality of your source and DAC. It is neither warm nor too analytical. This to-spec cable is made of a silver-gold alloy (I provided feedback on its design over the last two years) that has helped it reach new heights in performance. If you seek a transparent, natural, lifelike sound, this cable may be for you. It is a hidden gem. Please feel free to check out more about Dr. Ali’s extensive background in the Semiconductor industry and his avid audio interests, which have led him to design top-tier, affordable solutions for audiophiles, in his bio.

Those who know Dr Anwar are fully aware that he is always tweaking his components. Note that the USB cable selected by Stereo Times is a Mk 2, which means he was not satisfied with the Mk 1.
He said in his website: “We refreshed this cable to AA SiG XT USB Mk2 in 2025. It has separate sleeves for data and power resulting in lower noise floor. It also has better flexibility when orienting the USB plugs.”
