SMSL SU-1 breaks the rules! 

i mean electricity external noise are real and could possibly interfere data/ signal transfer, although yeah if everything good it would be as impactful as 256kbps mp3 vs 320

Glad you like it!

Same here. Very impressive

Did the SU-1 sound better than the dac in the Node? I have also have the Get 3 Node and would be interested in a cheap upgrade if it actually made a difference.

​@@jamesoconnor5903it improved the sound using a Node 2i for me as well. I love the SU-1.

Why is this one considered an upgrade to the E30?

heyy me too!! exact situation!! how did it turn out for you?

How did it work out???? Help us out!!!! Haha!!!

Thanks Slobo, cheers!

Too bad Tradutto measures so bad at Audio science review , ... 😁

​@@VirusForPrez😅

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

To be honest. For 80 Euro you can't go wrong with one of these. I'd say go for it.

Same here

Same here! I wonder if I really need usb version (204)? Don’t care about dsd or very high khz files….would the other inputs have the same quality as usb?

Can you tell me what brand of dac you had. Thank you.

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

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.

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.

@@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

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. 😅

SMSL SH-6 comes to mind. Really good amp that matches that price.

Ty so much for taking time to reply Srbj! Wishing you a great weekend!

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.

yes, it does sound stronger and clearer, your best ps would be the linear and adjustable voltage ps

I'm really curious why the power supply would make a difference? Do you have some keywords I could google or a link, so I can read up please?

you can't power down the schiit unless you turn your computer or notebook off..SMSl has a power switch...as for sound... playing a Bruce Cockburn cd ...Dancing In The Dragon's Jaws...through my sony transport via the coaxial...the SMSL was sonically superior to the Schiit

I have tried it with a cheap 5V supply, then phone charger, and with Allo Shanti LPS with very good power cable... Shanti cleaned up the sound nicely and created darker/deeper background. But given the price of that PS with the power cable, I can't say its a logical investment. Topping E70V goes for that kind of money. iFi iPower would be a more logical partner but I didn't have one to try it.

​@@iiWiReviews you should perhaps have mentioned this in the video.

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.

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

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

@@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.

@@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.

This is stereo only so it limit all your content to stereo sound. Given that you already have 5.1 system, you should try and keep the surround signal. That said, I'm not testing any multichannel devices so can't give any specific advice for it.

It would be a much more appealing product at 74.99. 😄

​​@@iiWiReviews maybe in an updated version they'll ditch mqa and instead add a remote or trigger in/out. that would be great! (and a separate power input would be Nice too 😀)

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. With the Internet fast enough to stream 24-bit/192KHz files, I see MQA as a "solution" in search of a problem that no longer exists. Maybe it was a good idea years ago, but simply is no longer needed.

Amazing value for money. A separate power input would have been nice.

if they let go optical, coax and MQA, perhaps we get some bucks using SU-1 😂

I've only had the original Modi 3 that came before the "3 plus" version. SU-1 is a clear upgrade in terms of overall detail retravel and dynamics to that one. Bur I can't say anything about newer Modi versions.
