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.

Our German Sheppard loves these
Size: Medium
These cost a bit more than tennis balls, but they are so much nicer and longer lasting. For starters, they stay cleaner than tennis balls because they’re smooth rubber. Dirt won’t build up on them and if anything does stick, like grass or soil, it falls off once the dog slobber dries. They’re also thick, so they don’t fall apart or blow out like a normal tennis ball does in our dog’s jaws after 30 seconds. Our GS chomps on these like crazy and the only damage they’ve suffered is a crack that developed from the edge of the hole, but the crack is growing very slowly and none of these balls have totally failed yet. The balls do whistle when thrown ant high speed and that may help a dog track and locate it, but I’m not sure. Our neighbors hear the whistling too so it’s far from silent. Lastly the orange ball is easy to locate out in our yard, but the dark blue practically disappears.

Great for smaller dogs
Size: Small
These two balls are perfect for the smaller mouthed dog that loves to play fetch. These balls are not only super durable (lots of teeth biting), but float in the baby pool we use for our miniature dachshunds. The value here is much better than you’d find anywhere else. The noise, if bitten hard enough, was “low” at best. Easy to spot/find if overthrown. Will definitely buy again once these are in bad repair; so far, so good-love these for my fur babies!

My dogs favorite balls
Size: Medium
These are great for my dog who always has to have a ball in her mouth. Not too hard so I don't have to worry about her teeth. They last for ever. They do lose their shape a little over time (like I said, she always has a ball in her mouth) they become a little oval in shape. They still bounce, she still chases it and she still chews on it so I don't think she notices or cares. I've gotten her a bag full of these over time and I have only seen one that she chewed a chunk out.

My Dachshunds Love These
Size: Small
These balls are durable, flexible material, highly chewable without being easily destroyed. I stuff them with Milkbone Maro Snacks, which are just the right size to twist into the holes in the ball. My dogs literally get an hour+ chewing and chasing entertainment from these. They chew them, they sometimes 'pop' out of their mouths, go rolling across the floor, dogs chasing them. This satisfies their urge to hunt prey. Dachshunds can easily tear this kind of stuff-it-toy apart. These have lasted for a long time without tearing or shredding. I would NOT recommend them for a dog much larger than a tweenie weenie. They're a bit on the small side and might be swallowed by a larger dog. It would be cool it they also came in a larger size (and probably ball wall thickness also) for the bigger dogs to enjoy. These stuff-it chew balls are better than the kong balls my dogs had before these. Highly recommend them.

My puppy’s favorite fetch toy!
Size: Small
Update Aug 27, 2024: After 10 months, these are still his favorite ball. He’s obsessed with fetching and plays with them all day. They do bounce really high. Unfortunately, the small size aren’t available for sale anywhere anymore. I tried the medium size, and he has a bit of trouble hanging on to them, but he manages. Weirdly, he prefers the orange one, but he also plays with the blue one. My 7 month old Shih Tzu puppy loves to fetch, and these are his new favorites. They’re small enough to fit in his mouth, and they are made of hard plastic, so he’s able to hold on to them. They have a lot of bounce, and this adds to the fun for him. I highly recommend them.
