SMSL SU-1 breaks the rules!

[@Simon_Hawkshaw]

Great to hear that budget equipment is improving so much. Makes getting back into music so much easier. Thank you for your time and effort to share this with us all.

[@AudioRamblings]

The SMSL SU1 is a fantastic DAC and your review nailed it. Your review prompted me to purchase this DAC and I can confirm it really is as good as you eloquently articulated. I am continuously comparing this DAC against others and using it with different audio set ups and it never ceases to deliver a compelling performance.

[@michaelkaercher]

I decided to follow your recommendation to bundle the SU-1 with a Fosi Audio V3 and an Wiim Pro. I use it with a pair of old B&W 6 Something bookshelf speakers at my PC. It is a really nice sound. I use the streamer to stream from Amazon and Spotify. My PC is connected via an optical cable directly to the SU-1. A simple but powerful setup. I hardly believe it is possible to get much cheaper the electronics for a real hifi system. Alltogether it was around 300 Euro. The sound is top.

[@richardchandra3641]

@iiWi Reviews - Thanks for another great review. So valuable to have someone with a good set of ears testing equipment for us. This seems like a great DAC, but it's missing a display, so I'd pass and pay more (E30 II?) to be able to verify the bitrate at which a stream is coming in. Probably just because it makes things more fun...

I went and bought one online. Had high expectations due to all the good reviews. After listening for a week, well.. it's just sounded ok. Not the giant killer i was hoping for. Compared to my Pure i20 ipod Dac Dock and my IQaudio dac pro pi hat, it was not the same league. The SU1 image is small, midrange little thin & dry and high not airy. I keep on switching between the su1 and the other 2 dac and well .. a bit disappointed. Guess if you are a beginner i think for the price its fine. It's not a bad DAC but better not gamble after you heard the good stuffs 😂.

[@titan90000]

Another awesome review as always. I just purchased this DAC as an upgrade to the original E30 I have had for a few years. I am pairing it with a SMSL DA9 that I purchased a year ago also based on your review of that unit. I was originally looking to spend around $500 US for a DAC upgrade that included balanced outputs. But, for the price and how excited you are on the sound I couldn't pass up giving this a try. If I like it I might put off getting a $500 DAC for 6 - 12 months.

Nice review! But what I miss in many reviews (not only yours) is the influence from adding a High-end preamp instead of using the volume control of the dac - if available…

[@JosepH06000]

Merci beaucoup pour cette revue 🎉

[@davidclarke6658]

The SMSL DAC'S are coming of age. The early ones I tried were a bit clinical and cold in sound with the added quality control issues. For their price, they did sound good, but not for the audiophile. Now I currently have the SMSL DO200 first edition and it really sounds good with a warm, richer sound signature and no quality issues. They definitely offer good bang for your buck now.

[@peterwu831]

The specs is top notch, this review is convincing. But I only listen to FLAC’s that are stored on my PC, and therefore I needed a streamer to deliver those files to my amplifiers. All streamers come with built in DAC, and it seams counter intuitive to stream - DSP - DAC, and than sending the analog audio to a higher quality DAC (internally ADC - DAC). I’m currently using Arylic Pro streaming DAC, at 24bit/192kHz the sound amazes me already. Hope SMSL could internally add a WI-FI streamer to SU-1.

[@hariboholmes4638]

You wouldn't be sending the analog signal into the new DAC anyway.. You would use the optical out on your Arylic to send a digital signal to SMSL SU1 so you would not be losing anything in the transfer. Depending on your other equipment you may see a minor improvement in tonality but if you are already happy with the sound from the streamer might not be worth it.

[@NeilBlanchard]

This SU1 DAC certainly seems to be a giant-killer! I am *really* hoping we can get a Geshelli Labs J2S into your hands - it starts at US $260 and has its 3 op-amps in sockets. It is also an AKM 4493 chip DAC, and has both balanced and single ended outputs. You can fit Sparkos SS3602 (the small Sparkos) on the XLR, and the RCA socket can fit the big Sparkos, the SS2590! These along with a decent 12V 50W linear power supply - are the best DAC I have ever heard. It easily bests the Ares II with the 12th Anniversary update, and the Schiit Bifrost 2/64 (and Bifrost 2), in my opinion.

[@rosswarren436]

That new Geshelli Labs J2S (Socketed) looks to be a great DAC. And I like that I can mix and match what op-amps are used. My preamp and amp don't have XLR connections so I can get a TI 1612 for those but get the Sparkos SS3602 for the RCA outputs, get it in white oak to match my stereo rack, and it still comes out under $500. Do you think the SS2590 is a noticeable step up from the SS3602? Worth the price difference? Where is a good source in the U.S. for the SS2590? Thanks!! (I keep leaning toward an Ares II 12th anniversary or even biting the bullet for a Gustard R26 because of all the "buzz" surrounding R2R DACs, but if the J2S can give me 90% of what the R26 offers at 1/3rd the cost, then it is a no-brainer). Edit: Hey Neil. If using the SS2590 which is a 6-pin Pro chip for the RCA socket outputs on the J2S, I'm confused. Do I still use ONE SS2590 and if so, what adapters are necessary? I see Sparkos has a bunch at their website. Thanks for any info you can provide regarding this. I've read some reviews of the SS2590 and they all are very positive.

[@kraig7777]

The option for the sockets on the J2 is almost as much as the total cost of the SU-1.

[@NeilBlanchard]

@@kraig7777 For the Sparkos option, yes. There are many other options you can get, though.

[@NeilBlanchard]

@@rosswarren436 Sparkos sells an adapter the stacks two of the SS2590 and makes them a DIP8 package. You also need a $2 riser they also sell to fit it in the RCA socket on the J2S - it has to tilt a tiny bit, and just touches the back of the RCA jacks. IF you also have the small Sparkos SS3602 units in the XLR sockets, then you need *two* risers for the big Sparkos; to get it up above the small ones. And yes, as good as the SS3602 is - the SS2590 is noticeably better. The depth and layering of the soundstage, and 3D feel of each instrument, as well as effortless dynamics and bass extension and weight and control - is just outstanding! As this little SU-1 shows - sometimes performance belies the price. As it happens, my AkitikA PR-102 preamp uses op-amps - the stock ones are OPA2134, and I had tried some OPA627 dual mono clones; which were pretty darn good. But in the process of swapping op-amps in the J2S, I was able to try the SS3602 in the preamp - and what I heard was impressive enough for me to buy two SS2590 dual mono DIP8 units. These are in the input and the output stages. I still have the OPA627 in the tone controls, and the two tape inputs; as I rarely use them. Now, the phono sounds better, and the headphones, too, by having the big Sparkos in there.

[@rosswarren436]

@@kraig7777 yes. I'm not comparing the SU-1. Didn't meant to hijack this thread, but I'm looking for a DAC less than say $700 that will compare with the Ares II 12th edition and even the $1600 Gustard R26. The SU-1 is obviously very good for its price and will compete with lower cost DACs from Schiit (their Modi 3), and others by Topping very well in many use cases.

So I just turn the device off but I wish I don't have to.

Don’t think of this message is me being critical, but what you really need to do for full disclose is compare this SU-1 to the Geshelli Labs J2 with the AKM4493 chip option, and also against the Topping E70 velvet. That will finally put the under $500 debate to rest. At least for now, lol. Too many people running around saying that J2 is best, and that may very well be, but J2 also has advantage of extra flexibility in connectivity, chipsets, and cosmetic options to enhance the unit or mitigate cost. But the priority for me is the sonic differences through the coaxial inputs between these 3 DAC’s..

[@iiWiReviews]

I do always test coaxial input because that's my preferred connection with the streamer. E70V is better than this one, full stop. I have a segment in this video comparing them.

Figure the licensing must not be too much these days for MQA, but yeah, why add any unnecessary costs if MQA is "going away". We'll see. There's always a chance they'll either get bought out by another company or come out of bankruptcy and still be in business.

[@davidmolyneux9014]

Could be they have "dirty" usb or house electrical and in such cases a better power supply can clean up those issues. Even with noise on the line the DAC itself would have to have a design that is slightly flawed in order to allow that noise to affect the sound. For instance I have a Topping D50 and it is susceptible to usb noise that was audible on some amplifiers. Ultimately if you have no issues with noise / electro magnetic interference then a power supply makes absolutely no difference whatsoever e.g. if you don't hear a problem then there is no problem. Hope this helps.

Hello Srboljub. Great review again. I have had one of these SU-1’s for about 8 months now. It’s so good for the money. I have a question please. You mentioned that the USB can be used as a digital input. Does that mean that I can connect an iPhone in this manner, via a lightning otg cable then USB C into the SU-1 please? This should give full lossless from Apple Music and the phone will power the DAC? Thanks for any advice you can give.

[@xgxhypxgx]

I bought the SMSL SU-1 for my 2.1 channel home theater to convert my TVs optical digital signal to analog for my amp and speakers which it does however the output voltage from the DAC is way too low (314mV rms and 870mV peak to peak) instead of the 2Vrms output that it claims.

[@iiWiReviews]

Not knowing your measurement method and supposing your results are good... It shouldn't be that low. Everytime I had a 1V DAC (portables) I have to crank up the volume significantly to match it with 2V ones. This time I went from SU-1 to Topping E30 II, SMSL C200, etc. And never noticed that SU-1 has lower output. So given that you didn't make any mistake and your measurements are correct, there's maybe something fishy with that unit.

[@carlsitler9071]

I have 3 dacs and with this review, I will soon have 4 (Sanskrit 2, Hidizs S9 Pro and Prozar).

[@seanb3303]

I have never understood how DACs can have differences in the bass department as their bass responses are almost perfectly linear. Not saying it doesn’t exist.

[@D1N02]

Dacs have op-amps for their output stage (Operational amplifiers). Those have sound characteristics. Other factors outside the chip itself can also weigh in.

[@iiWiReviews]

People hearing reacts much more to power of the signal than to its peak level. Power is level multiplied with time. So time domain performance definitely change perceived note strength. Also, when output impedance of a DAC and input impedance of the next component in line are joined, these can alter bass response to be different from that in lab environment. That's why changing a value of the output capacitor in the DAC output section can completely change perceived bass response even though it doesn't show in simple level measurements. There are even more factors to consider but it's longer story not suited for this comment I'm typing on a phone. 🙂 But whenever things seem simple and straightforward, they usually aren't. Like everything else in life I guess.

[@seanb3303]

@@D1N02 for timbre and sound coloration yes. But the bass response can be easily measured…a DAC that is plus 3dB in bass across a wide range…that would be noticeable. A DAC that is up or down .5 dB in bass would be very difficult to detect. That is why there is likely a psychoacoustic effect at play. Edit - the author of this video gives a good explanation.

[@seanb3303]

@@iiWiReviews good explanation. so much about sound is how we perceive it. Like there is technically no center image with stereo speakers but we can definitely perceive it. Psychoacoustics is fascinating area.

[@iiWiReviews]

Yeah, it definitely is. I'm actually into all of that because I majored in electrical measurements in the medical field, and studied cognitive psychology too. It was my favorite subject because it opened my eyes to so many things. There's more than meets the eye when we need to connect how measuring instruments read things and how we perceive them. It's logical but not always intuitive, so even good engineers can easily get sidetracked if they're not familiar with our cognitive system. Another thing I forgot to mention in the previous comment is that higher frequencies also influence how we perceive bassline, for example: slow, fast, clear, and muddy... because we have a poor hearing resolution in those low frequencies, so we rely on higher harmonics to shape those tones in our brain. That connection has been proven practically by manipulating higher frequency only, and test subjects reporting hearing bass differently - where bass measurements would be the same. Mastering engineers know this too, I've seen them adding higher harmonics to make the bassline feel more grippy and textured. It's the same with DACs and their components, small things like impulse response, harmonics, etc. pile up and make different sound for us. It's like adding spice on top of base dish ingredients - it can change our sensation of a meal a lot, even though 99.9% of ingredients are the same.

[@MegaEpstein]

I bought it few days ago to check it out. So many good reviews and comments, so I was intrigued how it's really sounds like. It has very clean sterile sound with metallic unpleasant High Frequencies. Midrange sounds a bit flat. Bass is really good but closer to the top it has strange metallic tone what i really don't like in this dac. I'm not disappointed but it definitely not my cup of tea

[@DP-qp8wr]

I use it with the Yamaha streamer and it sounds good.

[@Philip-xk5ui]

I always love listening to the audio vampyre!!!!!!

[@D1N02]

I was curious about this. Another reviewer took one apart and I saw it uses at least one LME49720MA op-amp which is usually seen in much more expensive dacs. There is another op-amp that is not marked, so probably they have tune it with two different op-amps. (I do the same with my little fosi/aiyima tube preamps that have two switchable op-amps)

[@iiWiReviews]

It sure feels like someone listened to this one and chose parts with care.

[@jackelofnar]

Great review. Do you think it's worth paying the extra for a SU-6? it will be attached to a SH-6 headphone amp

[@HiFiMods]

My topping e50 is arriving tomorrow! 😭😭😭😭😭🤣 But I need it to play DSD... apparently this one does it too..

[@BatteryAz1z]

Have you tried the E30 II Lite yet? Should be basically the same unit, but with some extra features.

[@markcompton6750]

Got one for 90 uk. Use it as a dac from my tv into a Musical Fidelity amp. Brilliant 👍

[@brooksc900]

Good news, thank you.

[@hameedn.b7004]

Pleasant surprise Nice review by the way What amp would you recommend to go with this dac?

[@iiWiReviews]

SMSL A300 is a great little amp, I did a review on it too.

[@JoseFerreira-zb7wh]

Would like it if you could review the new m300 se from smsl. It's a bit more expensive than the su-1 but it offers SO MUCH MORE in terms of features. (remote, screen, balanced circutry, headphone amp, volume knob, bluetooth, independent usb inputs for dac input and power...)

[@seanthompson3583]

Have you tried quality power supplies with this DAC? Thanks in advance for any observations.

[@MrRourk]

I just wonder how it sounds connected to a 300b SET Amp? Perhaps even a First Watt Solid State? I just worry about the errors in electronic format being to prevalent and exaggerated.

[@pask56argos85]

Hi, I wanted your advice on powering the Smsl DAC. Su 1, when I use the optical input, is 5 volt 1 ma or 5 volt 550 ma better? Thanks and congratulations for the channel. Good boy.

[@iiWiReviews]

Both will do but I would use the one with more Ampers. It means it works with less effort.

[@pask56argos85]

which of the two: 5 volts 1 ampere or 5 volts 550 micro amperes? Thank you

[@iiWiReviews]

5V/1A

[@pask56argos85]

THANK YOU.

[@pask56argos85]

hi, I tried with the smsl dac on 1 to play an mqa file from KZbin but it always comes out at 44100 and the LED doesn't light up. How can I fix it on Windows 10? I also downloaded the driver from the SMSl audio site. Thank you.

[@Fahad1999win]

Very nice detailed reviews! Can you recommend dongle portable dac/amp sound like topping e30 ii? In budget (I care about soundstage 3d sound full warm juicy sound signature) Thanks!

[@Nash-m9x]

Hi Nice review, I want to know if the Dac auto turns on like the E70?

[@HugoUS2]

Never had a DAC berfore and Im thinking to get the SU-1. What a good AMP should I get to match the SMSL? (like the same budget) Currently using a Edifier S350DB. Thanks!

[@djurdjica7050]

Edifier s350db su aktivni zvučnici pa već imaju pojačalo u sebi 😊

[@brucew13]

Hello, I am new to the DAC world, I am not into high end audio but the good value for money, I think this is where this DAC sits, after watching your video I decided to buy one of these mighty we DACs. I had to order from over seas, I have a question, using the coaxial input (have not used optical as have no cable) my SU-1 is distorted on the loud parts of the audio, all my other gear runs fine, tuner, CD player using RCA, PC and turntable. With all your experience what can casue this to happen? (I have a preamp driving a single ended EL34 tube amp) Thanks Bruce

[@fatboyvin]

Dear iiwi, I already have smsl D300 and topping E70 connected to SMSL A300 amplifier, do you think the SMSL SU-1 will pair just as well or even better with the SMSL A300? Your input will be greatly appreciated. Regards

[@gino3286]

Hi first of all thank you very much for all your precious work I have a question Did you experiment with different power supplies ? like low noise linear ones for instance ? usually the lower the noise the more the detail ... and maybe the lower the distortion

[@iiWiReviews]

Yes, I personally prefer to use a linear power supply everywhere it's possible. The result is always the same, calmer and richer sound with cleaner and darker background.

[@gino3286]

@@iiWiReviews hi thank you for the very kind and valuable advice The only thing that I would like to see is a proper and separate DC socket I don't like to mess data and Power lines together in a plug Expecially tiny USB plug I like the standard 5.5/2.5 mm type More contact surface

[@boubakane]

Have the c100(same+ Vol control & BT)🎉 What about vs topping e50?

[@morayjames92]

does the SU-1 offer an assortment of dac filter options? thanks for your review.

[@DIVA-MC-7]

and what about smsl su-1 vs geshelli j2s ? is it a real upgrade ?

[@chrislampe6397]

Wondering how this would compare to the D300 when paired with an A300?

[@scottbennett3119]

Does it sound better than the Modi 3 you reviewed a few years ago? Thank you

[@kdomster9141]

What power supply did you use ? Did you try quality Quality LPS and than COAX from CD transport input ?

[@htl211085]

Thanks for the review. I'm using SMSL Sanskrit 10th MKII. Is it worth to replace it with this DAC? Thanks

[@iiWiReviews]

I belive it is. This one should bring more dynamic sound and better deteil retrieval if the rest of the system can show it.

[@bst2896]

Which amp match well ? L30ii or L50 ? Thanks in advance my friend

[@pavlo687]

Is the Denafrips Ares still a good DAC? How much better is it over the SU-1 in your opinion?

[@wim1983]

Seem like a Fostex HP-A3 experience to me, except that Fostex has the headphone output with volume knob control, I might really tempted to buy the SMSL SU-1 for my mom TV box decode purpose as she does not listen to headphone. I'm not sure it's the chip design to be blamed, I tend to never like ESS Sabre vs AKM...

[@ysubman]

Great review! smsl M300 se seems good for its price, any review soon?

[@iiWiReviews]

I don't think I'll be doing that one. Too many SMSL models, they're like Pokemons, no matter how much you try, you can't catch them all. 😅

[@lungupetrisor3606]

How does it compare to the Lusya Usb back you reviewed a while ago?

[@MrRubasso]

I just connected an SMSL-SU1 to my Apple TV via the optical cable, connected to my Pioneer VSX-824. I noticed that when changing the audio source from the HDMI input (Apple TV) to analog input (Apple TV through the SMSL DAC) the volume drops by 5 to 8 decibels. Is this normal?
