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?
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.
Without a separate power input, how much faster does the battery drain on the cell phone?
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?

Brilliant Sound, Superb Value

Bought this is on review recommendations. Just had an 1990s DAT player refurbished, brought back from the dead after it had spent thirty years in the garage, now it plays perfectly but it had a somewhat compressed sound.This DAC has one of the very latest/best chip sets usually found in units at ten times the price, the DAC in the DAT is thirty years old so could benefit from the latest tech to give it a boost.Some people think all DACs are the same but they are clearly not, a listening test shows this very clearly, just as all headphones don’t sound alike. I have six DACs, some are good, some are not so good and it does not always relate to cost. A have a Fosi which is ok as a headphone DAC and pre amp which is ok, warm sounding but lacking clarity, a Beyerdynamic slightly better but not enough for the additional cost, a Chord Mojo which is very good used between an ipad and twin rca cables to an amp, a Prozor for 5.1 sound from a modern tv to ancient analogue cinema amp which was very cheap but sounds great and now this which sounds brilliant, better than the Chord but at about a fifth of the price.A good DAC puts air and soundstage into the music, separates the instruments and gives clarity to bass and treble.This one has opened up the sound of this DAT player, giving a clearer sound, very pleased with the result for such a low cost item.Also as the DAT is optical cable and the CD player, also from the 90s, is coaxial digital, this unit can take both items and you can switch between them using the button on the front.

Great Sounding DAC for a great price!

Brilliant piece of kit for an affordable price. Wanted to push CDs and it did just that. Really uncovers the sound. Soundstage has improved massively and high end has a nice shine to it. DACS are meant to be transparent and it does just that. For the price, you are getting a lot for the sound. Highly recommended.I currently have the output running into the AUX IN of a tube preamplifier to get some nice warmth and harmonics through the tubes that digital just doesn't have and I must say it does it brilliantly. Vocals pop forward with a warm tone and bass has a nice timbre to it. The Mids need some working.For this DAC, it's a must buy unless someone has the money to buy a more expensive one. Which by all means go for it.

Almost the perfect DAC, small problem with XMOS USB controller >> (Edited Dec. 2024)

Generally flawless DAC although I find I need some bass EQ compared to other converters. So silent and with such high resolution that digital volume control can be used with absolutely zero subjective loss in quality.The issue with the XMOS USB controller is that it goes into a standby mode after 5 seconds of no signal, apparently a default intended for when the chip is used in dongles for mobile devices (i.e. phones) to save a watt or so of power draw (silly for desktop and general hifi applications), and when it 'wakes up' it misses the first half second or so of playback which can get REALLY annoying if you're browsing files.It can be fixed in Windows by installing an XMOS USB driver from the SMSL website (the DAC is otherwise plug-and-play with the default, fairly recent Windows driver), but you then have to edit an XML configuration file to enable "Always On" as an option in its control panel (it's fixed to "On When Needed" otherwise).Search for "XMOS driver settings for no cutoff/delay" on the Audio Science Review forum.*** Edit Dec. 2024 *** the latest XMOS driver from SMSL's site (released in the last month or two) now allows 'Always On' available in the control panel (it might even be the default, I can't remember if I had to change it ), so my criticism above no longer applies.ETA 2 - A general tip - this little box draws practically no power, maybe a watt or two - leave it powered on 24/7 and it will last. If you keep switching it on and off (power cycling it) there's a much higher chance it will fail.

An amazing piece of audio gear for the price (and size!)

This is a decoder (DAC) and pre-amp, of the best audio quality. Actually, it's astonishing. Technically there are better DACs, but you can probably only measure the difference with professional equipment. Audio Science Review concludes "SMSL cuts the functionality to the minimum many need, to have high quality conversion of digital to analog for multiple inputs. Performance is superb for the cost, as it provides full transparency to the source. It proves that performance requires great engineering skill, and not a ton of money. A lesson that I hope one day high-end audio companies and their customers appreciate."I have it linked to a Pi2Aes (re-clocker linked to a Pi NAS music server) for my digital music catalogue and Web Radio, including MQA tracks.There's no volume control, which I rather miss, but that is available from the next stage (amp), so it outputs a good 2v. I'd prefer balanced inputs/outputs, but with this performance, who cares?This replaced a much larger DAC with multiple inputs, with greater functionality and lower cost. Did I mention how small it was? Astonishing.

Does the job in a anylitical way. Good if your system is lacking detail.

The SMSL SU 1 is a well made and featured DAC. However, if you have a detailed system already this DAC can prove a bit too forward in the mid and upper frequencies. The bass is there but a bit on the lean side. So much so I have reverted back to my Khdas tone board that gives a lovely level presentation, detail, image and bass. I use my DAC via coax to spdif of my CD player.

Install drivers and switch of safe mode for best sound quality

Brilliant budget DAC, DSD512 works well with jriver. You get better sound quality if you install the Xmos driver and switch of safe mode, this dac doesn’t like other usb DACs on the same PC (like my essence one)
