AA Sig USB Cable review by Passion for Sound
Correction: SiG Ref is not the perfect 90 Ω version of SiG USB. SiG Ref uses different materials for power delivery.

Testimonials from Customers

“Everything I hear exceeds expectations. I didn’t expect such a big increase. All sounds right and coherent overall. The DAC is now also powered by the LPS-1.”
Note: The DAC has the option to use its own internal linear PSU or powered via USB.

Bought AA SG USB cables and AA USB isolator….it simply works 
It somehow makes the sound more relaxed n easy to listen without suppressing the sound signature or take away any details
Simply put…I love it
