Review: Le stelle sono 5 ma potrebbero essere 6😉 Il DAC è molto ben costruito, piccolo ma "pesante" , tutto in metallo di buona qualità. Riguardo il suono: suona molto bene, per il prezzo poi suona in modo eccellente. Io utilizzo dac di vario tipo, anche apparecchi pro usati solo come convertitori, e questo piccoletto non sfigura affatto. Confrontato con il mio dac" di riferimento " ( uno che avevo assemblato anni fa, con alimentazione separata ,op- amp sostituibili, e, guarda caso con un vecchio chip AKM, perde solamente qualcosa nella gamma bassa, che è meno estesa e presente. Quindi in sintesi: se non volete spendere centinaia di euro ( parecchie) questo è sicuramente la scelta giusta. Sono rimasto abbastanza sorpreso, perché non credevo suonasse così bene
Review: Ok

## Questions & Answers

**Q: When I hook it up to play there is music for a second or two and then no music for a second or two. This repeats itself over and over again. Ideas?**
A: I do not have that problem with this device, HOWEVER, I do have that very same problem with another SMSL dac ( M500 MKII), and I have not been able to figure out why this happens. I do not use Windows, and I only play wav files with Linux based software, and Linux operating system. Make your own conclusions.

**Q: how come the output voltage is so low when I connect it to the optical on my TV?  I thought the output was suppose to be 2 Vrms.**
A: only tried whit coaxial in rca out

**Q: Without a separate power input, how much faster does the battery drain on the cell phone?**
A: It consumes very low energy. I don't use it via USB. I haven't tested it.

**Q: I'd like to listen to one of those new MQA-encoded CDs. Will the optical output of my legacy CD player pass the MQA-encoded signal to this SMSL?**
A: Yes, because the SMSL is reading, converting the signal and your legacy CD player is functioning as a transport only.

Después de un tiempo buscando información sobre Dac's encontré este y que gran suerte! Con una pequeña inversión optienes un Dac que ofrece una calidad de sonido que soprende por lo pequeño que es el aparatito, eso sí muy bien construido y decodifica la senyal digital y la transforma a analógica por salidas rca a tu amplificador, previo, receptor AV etc. Actualizando y dando una calidad de sonido increíble, con una nitidez y claridad matices sorprendente superando a otros 2 o 3 veces más caros, con un coste inferior pero no en calidad de sonido i acabados. Sí buscas un Dac sin tener que invertir mucho dinero pero con una calidad que sorprende este es tu Dac, no lo dudes. Tu música en streaming mejorará gratamente y solo desde tu smartphone, tablet, pc, eso sí que dispongan de transmisión de archivos de audio a través del Puerto usb-c, yo utilizo un Xioami Mi 9TPro y funciona perfectamente ya que envía audio y alimentación al Dac sin ningún problema, también tengo un Poco X3y perfecto pero tengo un Xiaomi Redmi note 11s y no lo puedo usar hasta el momento, no tengo ni idea porque no alimenta este Dac yo uso la entrada usb-c del Dac, que también es Puerto de alimentación de este para darle alimentación eléctrica tienes que usar un cargador de móvil, yo en mi caso cuando no lo uso a través de mi smartphone como no tengo toma de corriente eléctrica cercana uso una Powerbank y no me da ningún problema funciona perfectamente. También lo puedes usar a través de sus entradas digitales coaxial o óptica como Dac externo de un CD, DVD, streamer mejorando su calidad de sonido, yo lo he conectado con la entrada coaxial con mí CD Pioneer PDR-W839 Multi-CD Changer / CD Recorder y la mejora es notable, igualando a mi CD de referéncia dedicado el Marantz cd-48. En conclusión, por el coste que tiene y la calidad que ofrece no tengo dudas que es una gran compra este Dac, es pequeño pero matón.
