Review: Una buena sorpresa - Hace unos años tuve oportunidad de probar unos DACs basados en chips de ESS, que entonces empezaban a ser considerados como lo mejor que la tecnología de audio digital ofrecía para la reproducción musical, y mi impresión no fue buena. Me pareció que el sonido era un tanto metálico, estridente, muy poco natural, una opinión subjetiva, claro, que no coincidía con los resultados técnicos. Después resultó que en algunas pruebas había algo raro en las frecuencias medias (la ‘joroba’ ESS la llamaron en un foro técnico), problema que luego fue resuelto en la mejor implementación de los chips, por lo que decidí probar de nuevo con este SMSL SU-9n. Después de un mes de escuchar mi colección de música en mi equipo debo decir que este pequeño aparato es estupendo. Sin ruido ni distorsiones, una claridad y separación de instrumentos muy notable, una presentación ejemplar del contenido musical de los archivos que no agrega ni quita nada; si una grabación es de menor calidad que otras este DAC la hará evidente. SMSL ha hecho un muy buen trabajo. Repito, este SU-9n es de veras bueno, y le hará compañía a mi preferido sin pena. Tiene, sin embargo, algunos detalles que pueden molestar o no al usuario: de acuerdo a unos análisis la calidad de reproducción de señales DSD no está al nivel de las de PCM –para mis oídos esto es más bien académico, yo no escucho diferencia; más notorio es el diseño de la chica pantalla que muestra en números grandes y blancos el volumen y en una ínfima tipografía la calidad de la señal (el rango de muestreo) que me obliga a acercarme para verificar si lo que envía mi computadora es lo que recibe el DAC. También está lo del Bluetooth, que no le veo uso para mí, y una gran cantidad de filtros y de coloraciones que aún no pruebo; soy más bien de vieja escuela. Un pro valioso para mí: no tiene MQA. Aunque falta la prueba del tiempo -la longevidad de este aparato- puedo recomendarlo a quienes le gusta escuchar música, que es justo lo que entrega.
Review: Huge On Value And I Said No To MQA! - I've been living with an "emergency" DAC purchase (Schiit Audio Modi Gen 1) for many years after my very high end unit gave up on me prematurely. At the time, I was shifting as an audiophile that was chasing that "last 5%" to demanding serious bang for my buck. I had intended on upgrading to the Schiit Bifrost eventually, but the Modi served my system reasonably well enough. I've been paying attention to the DAC market as it has hit that "sweet spot" where the technology pretty much at the peak of perfection these days. It felt like the right time to upgrade. I seriously considered the Schiit Bifrost2, but again that "value seeker" in me urged me towards this recently introduced SMSL SU-9n. The spec's and measurements were absolutely stunning, putting it squarely in the top 10 DAC's available in the world at the time of my purchase. For sub $400, I just couldn't seriously consider anything else. My 2 channel HiFi system is fairly decent. I'm rocking a 1978 pair of Klispch LaScala's, overhauled with ALK Engineering crossovers. I run a Schiit Audio Freya preamp into a Bel Canto S300 amplifier using balanced connections. I run all my audio through either Bluetooth or a media PC these days, don't even have a CD player anymore. This DAC upgrade finally allowed me to get signal 100% balanced from input to output. Let's talk impact! It was a notable and distinguished upgrade for me. Light years beyond the Modi and that was a pretty good DAC. I get an excellent soundstage on the Klipsch's, wide and with excellent separation of instruments. Imaging is excellent, it's super exciting to close my eyes and just envision the soundstage. Demanding tracks seriously push my Klipsch horns harder and with greater clarity than I've ever heard them. I don't like to describe DAC's as being "warm" as it's a poor term for digital to analog conversion, but this DAC is neither overly shrill or lacking in detail. I have also noticed a marked improvement in the "tightness" and general response in the low end. Both of these aural extremes can present problems with legacy Klipsch speakers and this DAC seems to fit reasonably well, sonically. I would describe the sound as trending towards analytical, but with good "punch and forwardness" that balances musicality fairly well. This DAC definitely likes electronic music a lot, but is no slouch with traditional forms of music either. This DAC really shines in highly dynamic and suddenly silent passages, it's outright exciting when it gets dead quiet. I don't find myself longing for any more clarity, I think I've finally hit the limit of what the Klipsch LaScalas can do with this upgrade. I am not bedazzled by all the new audio formats (e.g. DSD, MQA) being pushed out there. In particular, I could be considered "anti-MQA" as my research into the format and company has really turned me off. For that ultra high-end audio itch, the age-old 24bit/88Khz tech still suits me just fine. I was really happy to see SMSL offer this non-MQA version of the SU-9, it was a selling point for me. There are a few, minor differences between this unit and the MQA version of the SU-9...but not anything major that would detract from the experience. Most notably, Bluetooth UAT is missing in the SU-9n, but when I want high end, it's going over a wire. Drawbacks? This unit is not aesthetically pleasing to me, at all. I'd opt a silver chassis myself and would prefer if it didn't look like it just fell out of a tree. (That "just slightly" off-center display irks me.) While the display is improved over older SMSL DAC's, I'm just not in love with the look overall. (I do like having a display, it's nice to see what the DAC is actually doing.) There's lots of knobs and dials I've yet to play with, but for the most part I'm uninterested in a DAC filtering audio for me. If I wanted those dials, I'd have an EQ...and I don't have an EQ. (I do attenuate my LaScala's tweeters by -3db via my crossovers, though.) Overall, I don't think it's a bad decision at all to settle on this DAC. You can chase that "last 5%" at immense cost, but I'm not that audiophile anymore. For the bucks, this DAC presents a massive value to the HiFi purist. That's pretty much my system these days...excellent gear getting me 95% of the way there. And I couldn't be happier. For now.

## Questions & Answers

**Q: Can this be connected to my Yamaha rx A780 recivier ?  For a better dac**
A: Technically it can be connected to your "audio 4" or "audio 5" inputs on the back of your receiver. However, I don't know how it will sound. Will you be listening in only stereo 2-channel mode? If so, it may sound great, depending on your source material. If you listen through a home theatre multi-channel mode, I have no idea how it will sound, as the dac only is inputting stereo left and right. That's the best I can answer, since there are lots of variables. Good luck!

**Q: Does this include a USB cable?**
A: Yes it comes with a usb cable, but it's very short.

**Q: what is the return policy for this dac?**
A: If you bought it from Amazon, you should have at least 30 days to return it.

**Q: Can you record audio into my computer (Windows 11) with either SU-9 Pro or SU-9N? Through ADAT in or Coaxial in on the back of your SMSL units**
A: It's a DAC – not an ADC. Listening, not recording.

### ⭐⭐⭐⭐⭐ Has a great sound - better than my built in Arcam Alpha 7 CD DAC
*by J***S on 25 July 2023*

I wouldn't call myself an audiophile however I realise that the standard DACs blur the audio and smear the timing of CDs. I can hear the difference this S.M.S.L SU-9n makes - instruments are clearer for example (I connect the coaxial output of my CD player into the S.M.S.L SU-9n). There are a lot of settings in the menu - some make the bass very powerful. The display light can be turned off (NB. not that obvious how to do it). The Bluetooth I thought I'd never use but it's easy to play my smartphone into my hi-fi now (occasionally useful).
