The Singxer SA1 is an high-performance, full-featured headphone amplifier and preamplifier. Pure Class A design and discrete, fully balanced circuitry. Completely analog, there is no EMI interference from digital control to disrupt the audio signal. ROHM input transistors provide very low noise and excellent performance. The output stage uses multi-stage current amplification, similar to that found in a high-power amplifier. Each channel has 2 pairs of 4A ON Semiconductor transistors to ensure low internal resistance and high output power. These circuits also incorporate a complete protection system against overcurrents, overloads, short circuits as well as thermal protection, DC protection and switch-on delay.

This SA-1 is very complete. Single ended inputs (RCA) and balanced inputs (XLR). For the headphone outputs, the amplifier offers 4.4mm jack, balanced output and 4-pole XLR balanced output. The 6,3mm jack is singled ended output. The preamplifier outputs are unbalanced RCA output and balanced XLR outputs.
The headphone gain can be changed to fit any type of headphone. Low sensitive and high sensitive, they all match.

This is a good amp for the price. Can easily compete with amps up to at least 1000 euros. Sound is more engaging and enjoyable than the good, but more sterile Topping family competitors. Thing I noticed is that the front switch doesn’t really turn it off (it still keeps drawing about 3 watts), with the back switch it turns really off. Also this on/pre/pha switch can cause serious DC offset peaks, at least on the XLR-outs, which can be a serious issue with certain power amps driving speakers (Singxer needs to be turned on first and turned off last to prevent issues). Not sure if this is only my unit (btw I didn’t put jumpers on the power supply protection circuit).

Wat een fijne versterker, muisstil, zwarte achtergrond. Super veel details, erg mooie plaatsing van instrumenten en artiesten. Superstrakke basweergave. Speel met een Meze 109 pro hoofdtelefoon. Had hiervoor een creek obh21 hoofdtelefoon versterker maar dit is zo een grote sprong voorwaarts dat heb ik niet durven dromen. Vragen werden snel serieus en eerlijk beantwoord.
Kortom heel tevreden.

The amplifier- 4.5 stars. Very good class A . Sound wise I find it more enjoyable when compared to A90. Price/quality ratio is great with SA1. Measurements are also excellent (see ASR for Amir review).
Magna Hifi service- 10 stars. Excellent pre and post sale customer service from Rob and Jos. My SA1 had an issue with power protection. I was promptly resolved. Based on my experience I strongly recommend Magna HiFi.

This is my first “proper” AMP (I had a dragonfly before) and it just makes the music so engaging, lively and fun to listen to compared to some other amps I tried, even ones at twice it’s price point.
Also worth mentioning is that the staff at Magna have been great to me this whole time, there were a lot of delays due to Singxer but Rob and Jos were always honest with me and quick to respond to questions.

This amp price/performance ratio is ridiculously good!!! Just get it. Sounds best connected to a balanced DAC, Rca sounds amazing too.
Very Happy customer – great Magna service!

High end does not have to be expensive. This preamp proves that. I’ve heard a lot in my life but this is a no brainer.
Thanks also Magna Hifi for this recommendation!

Sounds great and features are simply unbeatable for this price. Replacing my Topping preamp – has never been able to charm me anyway.
