Title: Broke after 10 days of use, but now fixed
Review: Update: March 13, 2024 (previously 1 star rating, now I give it 5 star rating).After several exchange of messages between Leaudio seller and myself, it was suggested that I install SMSL SU-1 driver from smsl-audio.com official website, which I did. To my surprise that fixed my DAC! Now I am finally able listen to music from my PC sent to SU-1 by USB cable, which is connected to my SMSL A300 by RCA. It seems the driver installation to my Windows 10 fixed whatever issue I was having with SU-1 DAC. As result of this, I'm updating the previous 1-star rating to 5 stars. As for the sound quality from SU-1, as stated below, it's an improvement over my SMSL A300 amplifier by 15 - 20%, but more specifically, it is the sonic clarity and separation that are the most notable. Though a minimal audio improvement over my amplifier's internal DAC, the sound clarity and instrument separation are noteworthy, and for that I give a 5-star rating. Also, through this DAC, vocals seem to be slightly more forward and clearer.March 6, 2023, initial review, I gave it 1 star rating due to the DAC's failure after 10 days of use.Bought this SMSL SU-1 DAC in November 2023, but I couldn't use it since I didn't have a pair of RCA cables to connect it to my class D SMSL A300 amplifier that I purchased from Amazon at the same time. The DAC was on Black Friday sale, so I figured to try it with my new amplifier.Fast forward to Feb 2024, I finally ordered a pair of CESS 163-4i RCA cables, connected the DAC to my amplifier. The SMSL SU-1 DAC improved the quality by about 15% over my SMSL A300 internal DAC. I used the DAC on and off for about 10 days, then today it simply failed on me. It simply fell dead silent while playing a music file from my PC (PC to USB cable to SMSL SU-1 DAC to RCA cables to SMSL A300 amplifier).I tried another RCA port in the back of my SMSL A300 amplifier, but that too didn't work. The DAC simply does not work at all. I also tried powering down my amp completely, unplug RCA cables between the DAC and the amp, then powered both up again, and toggled between various input options in the DAC to no avail (USB, coaxile, and optical just in case the internal circuit's connectivity had glitched and that toggling among input sources might reset it).The source-light LED still functions on the DAC, but I get absolutely no audio signal going into my amplifier. Heck, I even rebooted my PC just to see if that may be causing an issue, but it was futile. After 2 hours of wrestling with the connections and toggling between input sources and settings, I gave up.Now I'm back to connecting my PC directly to my SMSL A300 amplifier by USB cable, which works fine. As far as SMSL SU-1 DAC is concerned, it was a decent DAC for the price (while it worked). However, the unit I got simply failed after about 10 days of usage.I'd instantly return it for a refund, but the Jan 31 deadline return date is closed, so sadly it's not an option for me. A good-sounding, affordable DAC with a high quality DAC chip, but in my case, I must have received a lemon, so quality control seems questionable. Maybe it's just bad luck on my part, but I still wouldn't recommend this DAC to anyone. You'd be better off to spend a bit more money on a high quality DAC with its own power supply built in.Update On March 11, 2024 I emailed with photo attachments of the failed SMSL SU-1 DAC to [email protected]. According to their site, they'll honor their product warranty up to 6 months with either a repair, replacement, or refund if their product proves to be defective. Hopefully they'll reply in a timely manner with a resolution. As others may encounter a product failure after the Amazon's 30-day free return policy, I'll post further updates for reference.Update, March 11, 2024, 8 hours later, shenzhenaudio.com support staff replied my to my email, asked for the Amazon purchase invoice and order number. I forwarded them the necessary information.According to their reply, they'll forward my case to their Amazon Support Team. I hope this will be resolved asap as I'll need to either get a replacement DAC or get a refund and buy another DAC, so for now I'm stuck in a limbo with 70 bucks tied up in a failed DAC unit. For now I'm stuck to using the internal DAC of my SMSL A300 amplifier, which is quite ok, but I did like the somewhat improved audio fidelity of SMSL SU-1 DAC.Update March 12, 2024. Got a reply from Leaudio requesting detailed info on what's wrong with my SMSL SU-1 DAC. I forwarded an account of how it simply stopped working while playing music from my laptop connected to it by a USB. Also forwarded 3 photos of the DAC. Hope this matter will be dealt with either a refund, replacement, or repair soon, because at this point, the DAC is useless.

Title: Best DAC for the price
Review: I've had some decent DACs in my time, also I have a friend with some high end expensive ladder DACs and a well thought out audio room and system so I have experience listening to combinations of high end audio. This SU-1 DAC performs really well compared to everything within reason. When I listen to my speakers set up in the "magic triangle" and some well recorded stereo tracks I can hear instruments and vocals coming from the right position in the image and its slightly forward and holographic. The sound is natural and detailed without being bright. I think to get a better DAC than this you will have to spend hundreds more for very small gains. The only gripe I have is the USB-C input is both for power and data. If you have an electronically noisy power supply some people have reported audio noise floor in some rare cases. For my computer with a Seasonic Platinum PSU I hear no noise from the speakers/DAC/amp combo I'm using. The power should be separate from the USB data so it could be powered by a separate low noise PSU but I get that this is DAC is all about budget so its acceptable.

Title: Great companion DAC to Wiim Ultra
Review: I was disappointed with the veiled sound of my new Wiim Ultra that I use in my bedroom and knew it could use more separated sound staging and clarity and snap attack. I bought this not realizing it was intended for CD transports but I swear the DAC in it really upgraded my Wiim Ultra sound quality by a noticeable margin. The sound quality and presentation can compete with my far more expensive gear in my living g room. At least to my audiophile experience I can appreciate the subtle improvements and this is a very nice device at an affordable cost. I've only had it a day so hopefully it will last. I love the input options and clean form factor.

Title: Great sound at a reasonable price but comes with a caveat.
Review: It just blow me out of water when I switched it with my 10 years old external sound card. I thought my old sound card is already decent enough but comparing to this DAC, they are definitely not in the same league. The first thing I noticed is the clarity/detail comes from this little thing. I have DROP AAA 789 + HD650 setup, and use Apple Music Lossless as music source, I feel this DAC really brings the best of the two. Aside from that, the low becomes deeper with no compromise in quality. It makes my whole setup really addictive!However, all the good stuff comes with one caveat, that's the driver if you are using Windows. I noticed a non-stopable clipping sound when I launched Chrome browser, the only way to stop that is to close the browser or launch Apple music before launching Chrome. It's not a big deal but I just can't give it a 5 star rating.Overall this is a great DAC for the price!

Title: Significant contributor in a budget system
Review: I have recently set up 2 audio systems in our home using remaining pieces from our earlier years of home theater. Many things were still needed but budget priorities reigned supreme.I have always liked polk audio speakers from the early 2000's specifically rti28 and rti38 bookshelf speakers.I found a pristine pair of polk rti38's on Ebay and they are being fed by a wiim mini streamer into an smsl su1 dac and driven by a fosi audio bt20a pro class D amp. A polk psw103 sub (craigslist) handles the lows.The music is detailed, the definition of instruments is present, especially with well produced audio. The speakers do disappear as the soundstage does extend a bit beyond the speakers laterally and center imaging is quite good.The speakers are 8 feet apart, 18 inches from the wall with tweeters at ear level from my listening position, and pointed at me seated 8 feet from them.I have listened to these speakers not using this dac and it is noticeable that this little dac enhances all aspects described above.Audiophile? Of course not.Very pleasing music quality? Absolutely.Highly and humbly recommended for a great budget system.

Review: Me gusto en primer lugar que llego en el tiempo acordado por Amazon.Me encanto la calidad de construcción de este es metalico , probalemente sea aluminio muy bien trabajado , no cuenta con control remoto pero el boton para seleccionar la entrada se siente de muy buena calidad.Cuenta con entrada óptica , coaxial, y USB. La mejor calidad que he podido tener es por medio de USB a mi computadora. Ya que por la entrada óptica mi pc tal vez no sea capaz de enviar 192 khz 24 bit y mucho menos 398 y 768. Este dac por medio de USB 3.0 soporta 384 khz 32 bits y 768 khz 32 bits por medio de usb tipo c. Es una mejora notable en la música cuando lo usas con TIDAL y reproduces Archivos MQA, VS Alac de Apple y Flac simplemente mejora la calidad de audio. Lo probe con un Sony Genezi MHC-GN800 si tienes mejores altavoces notaras aún más la diferencia.Prefiero usarlo por USB directo a mi computadora tiene compatibilidad de todas las formas y excelente calidad de audio.

Review: Jedem Musikliebhaber mit halbswegs brauchbarer Stereoanlage sei dieser kleine Zauberkasten bei Vorhandensein eines digitalen Ausgangs sehr an Herz gelegt. Der Gewinn an Klangqualität (Auflösung, Dynamik, Tiefe, ...) ist immens und auch für Gelegenheitshörer unverkennbar. So habe ich z.B. einen Billigstreamer von Majority für wenig Geld in eine völlig neue Klangdimension katapultiert und kann mich für zusammen weniger als 200 € sehr zufrieden dem gehobenen Musikgenuss hingeben. Vorsorglich aber eine Warnung: Schlechte Aufnahmen aus früheren Jahrzehnten ohne Remaster bleiben schlecht; Wunder vollbringen kann die Technik noch nicht...

Review: Al di sopra delle aspettative; la dimostrazione che oggi non serve spendere cifre elevate per avere una buona qualità audio. Lo consiglio vivamente.
