Fantastic preamplifier for an unprecedented low price! This is my best hi-fi purchase in recent years.

First of all and most important: I love the sound! This amp is made with high grade parts and feels very solid. Fully discrete class A preamp. Highly recommended!

Nice bass reproduction, nicely layered! Deep stereo image and the authentic class-A sound. Well done for the money!

Seems to work well with my Wireworld Silver Sphere HDMI cable and my Holo May KTE. My whole system sounds ‘right’ now in a way I’ve never heard before. It’s a feeling that’s similar across all input formats and musical genres. Excellent soundstage, neutral frequency response, realistic timbre, excellent micro detail, good low end drive and the blackest of black backgrounds.

It is outstanding DAC. Sound quality is amazing. I use model of 2022 as DAC/preamp with Nelson Pass's amplifier Aleph J connected via XLR output. I also satisfied with service of 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.

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

After ordering, delivery was fast, because it was on stock. My MicroRendo has USB out and I needed a converter, which has data simultaneously available in AES, SPDIF (RCA and optical), I2S (HDMI, RJ45) format. Instead of the included PSU, I powered it with a SBooster 9V lineair power supply and the USB port with a SBooster 5V lineair power supply. I use two DACs simultaneously, a Sabre DAC for the loudspeakers, a NOS DAC for the headphone. This is the best sound, I can get with my DAC's, even Spotify sounds like near_CD quality. This is a DDC and just a link in your whole equipment chain, so the final sound depends on the rest of your installation. But as they say "garbage in, garbage out", the source quality is the start of the chain.

Had a great listening evening yesterday. To be honest, the sound with the Singxer SU-6 (coming from my Vortexbox Audioserver premium xl) is breath taking. I am really surprised how it works that way and why others are (probably) do not include this technology …. in addition, I have tried several components and settings, nothing works like the singxer …. Great weekend! Michael

The Singxer su6 tagled your equipment up to a much higher level. Especially if you're playing with a Nucleus, Nuc or Rhein z1 you certainly have to meet this sensational SU6 . Stronly recommended i’ve you like timing; rythm and refined heights. I’ts you’re number One choice.

First, outstanding customer service from Jos. I was sent the wrong item and he took care of the issue immediately. Now on to the review. I had been using my Gustard R26 connected to my pc with a wired internet connection. When I received the SU-6, I connected the pc via USB and the R26 with IIS. The sound was better, but not by much. My initial impression was I paid HOW much for this? I told Jos I was not impressed with the SU-6 and he told me to wait. A couple of weeks later I turned my preamp and amp off but forgot to turn off my PC and left roon running overnight. When I turned my preamp and amp back on the next day, I was stunned. The sound had completely changed. There was more clarity in the music, more depth, and a bigger soundstage. I now have about 80 hours of use and the sound has improved further. I was told the sound will reach it's peak improvement after about 300 hours. The SU-6 makes the journey to get there fun and enjoyable. I highly recommend it, it's well worth the price. Just be sure to give it time to reach it's full potential.

I am very happy with the sound. The first hours it wasn't very impressive but now the sound has improved a lot. After 150 hours the SU6 started to shine!

Sounds amazing, already I think it beats the naim 272. Thanks again for the great service

Nice service, everyting prepared and fanastic product. Simply the best hifi-shop ever!

Just one magnificent expression!! I'm not going to dwell on the contributions on music because they are all over the place. I think this is the most impressive update since 2016 my first Audio GT purchase.

I really wanted to say was that the Master3 amp is really marvelous, and coupled with the Vacum it's superb!

It was a huge upgrade with the i2s bridge in front of my rockna signature dac! What an improvement!!!

I am so happy, withinthe first minutes - and this is ONLY with a quick test that everything is working - a simple RCA connection / SE out. I plugged in my HIfiman HE6sev2 - just to start with the bigger drive challenge and my goodness - from the first minute on - magic. And I will get some balanced signal into it tomorrow. I can see a great music listening wonderful journey ahead.

GREAT !!!

Present for my husband. Wow! I use it too, so easy and great sound.

This device sounds really great to me, a big improvement, much more than the SU2 alone! But in combination it is really nice

Das Gerät ist fantastisch. Erst jetzt erkennt man wahrhaftige Instrumente, die Bässe spielen nuancierter man hört jedes Detail und eine gewisse Magie verbreitet sich im Raum. Die LAN Aufbereitung spielt eine grosse Rolle

The RJ45 Isolator connected. Ethernet cable runs via TP Link over the 230 volt line in the house. Clearly an audible difference! Deeper bass, gossamer finer, tighter highs and so there seems to be more dynamics. Less garbage in is also less garbage out, right. As far as I'm concerned, successful. Costs anything but the final improvements are always the most expensive. ;-)

Sounds amazing, it beats my NAD M33. Thanks again for the great service

Excellent value for the money. Unfortunately, the market for these types of cables is still very small. In the future, I will make the upgrade to the pink faun. For now, is this the best in my opinion.
