Singxer SA-1 V2 is the latest fully balanced Class-A amplifier from the brand. It offers a completely discrete analog audio circuitry to provide a superb sound signal amplification with ultra-low noise-floor and distortion.

Fully Independent Class-A Analog Amplification Circuit:-

Class "A" is a type of amplifier circuit that reproduces the whole signal wave resulting in a higher-fidelity output with no cross-over distortion. The Singxer SA-1 V2 features a true four-way fully independent, fully discrete Class-A amplification circuit design. It is a pure analog circuit with pure analog control without any EMI(Electro-Magnetic Interference) caused by digital controls. 

Fully Balanced Output:-

The Singxer SA-1 V2 is a fully balanced audio amplifier with balanced XLR signal inputs. The audio signal is then amplified using top-class amplification circuitry providing low-distortion and noise floor. For final output, the device features 4-pin XLR/4.4mm Balanced headphones output ports. For Pre-out the SA-1 V2 is equipped with XLR balanced line-out too.

The SA-1 V2 also features 6.35mm single-ended headphone output and RCA single-ended pre-amp line-out functionality.

Super-Clean Signal Amplification:-

The Singxer SA-1 V2 chipset features high-quality premium components that enable the device to provide a super-clean output with ultra-low harmonic distortion and noise ratings. The output has a THD+N rating of -120dB @ 1kHz A-weighted. The output has a super-low noise floor even with sensitive pairs of IEMs and Headphones there is no sign of distortion or noise. All you get is a pitch dark background where the minutest of musical details pop out making the output full of life.

Circuit Protection:- 

Singxer has designed the internal audio circuitry of the SA-1 V2 to provide protection against electrical issues like overcurrent, overload, overheating, short circuit, Start-up delay, and more. So users can enjoy their music without worrying about power causing any trouble to the device.

Very good product
Size: Medium, Color: (001) Black / Black / Pitch Gray
I purchased these to wear inside lowcut slip on casual shoes, I don't particularly like to not wear socks in my shoes for hygienic reasons. Prior to purchasing these socks, all I could find were those made of very light beige hosiery type material , and my slip on shoes would slide around a bit. These are light weight and breathable athletic type material, with a very good gripper strip at the heel. One pair of my slip on casual shoes have a particularly lower cut in the toe area, but the shoe is black and I chose the black color and though I see a hint of the sock there, it matches and does not detract from the look of the casual solid black shoe

They stay out! No more sock wads!
Size: Medium, Color: (100) White / White / Mod Gray
Best no show socks ever made!!!!! I've been struggling for 2 years to find ones that actually stay on your foot, even other national brands, and I just became content wearing my sneakers without socks. They ALWAYS slid down into my show & I ended up walking on a wad of sock until I could fix it...or usually just took them off after a couple of tries. Enter Under Armor!!! They a mid weight, but not very thick & still breathable. They work too by actually staying on your foot! Not once have they slid down into my show!! Very comfortable but they could be a little more affordable.

Ive tried so many no show socks but I love these. This is the 3rd set I've bought. They never slip off and the material is thin and breathable. Perfect for working out.

True no-show socks that don’t slide down!
Size: Medium, Color: (100) White / White / Mod Gray, Size: Medium, Color: (100) White / White / Mod Gray
This is the first pair of no-show socks I’ve tried that actually don’t slide down into my shoes. Trust me… I have tried lots of different pairs and this is the one! They fit perfectly. They’re not too thick and they’re obviously durable because I wash them after each wear, so daily.
