DON'T BY SMSL SU-8 from Massdrop!!!!!!!!!!!!!!!
This is a WARNING for people who are looking to buy the SMSL SU-8 from Massdrop.
Based on my experience and frustration.
Massdrop does not provide any warranty for this product.
Even in my case 30 days return condition was not possible as delivery to New Zealand took 31 days.
I have contacted to Massdrop and was rejected for RMA.
In this case better to buy directly from manufacture dealer as they provide 12 months warranty and super-fast free international delivery with price 249$
I was a big fan of buying audio gears from Massdrop, but this unit let me down and rises concern for the future relation with Massdrop as the customer.
Bought on 01 September 2018, Delivered 02 October 2018 (30 Days) Details attached in photo.
First week I was running via USB cable and was very Happy.
But after 2 weeks decided to use Toslink and Coax inputs and have found, that my unit has some buzzing noise via toslink/ and coax input. When via USB the noise was still present, but less audible.
Noise can been described as high frequency (coil wining) buzzing noise with combination of some tapping sound every second (as second arrow on the wall clock), very noticeable when music on pause and headphone amplifier on max volume. This noise does not affected by SMSL SU8 volume change. It is constant and was amplified by Emotiva amplifier's volume knob.
My setup can be seen on my profile:
Comp >> SMS SU8>> rca>> Emotiva A100 BasX>> HD 6XX, 7XX etc.
From comp to SMS SU8 via USB (Less Buzz) , but via Toslink ( Noticable Buzz).
Also tried : Comp>>USB>> Topping 7>>Digital Coaxil>> SMS SU8>> RCA>> Emotiva A100BasX>> HD6XX (Buzzing )
For control: Comp>> Toslink>> Topping7>> RCA>> Emotiva A100BasX>> HD6XX (Silence and No Buzzing)
Buzzing comes when listening any music (youtube)>> pause>> volume max on amplifier.
As you can see from my posted setup pictures I have a lot of audio gears and have tried every single combination with swapping wires and amplifiers. The source of noise is SMSL SU8!
Technically when you pressed '' BUY'' button for this product, you start gambling what kind of unit you will get. And Massdrop will not take any responsibility for defective product, because slow delivery outside of US make impossible 30 days return condition happens.
So, after 3 months. I have defective unit which is impossible to listen with my new setup( via Toslink)
It was mentioned in specs TND 0.0003 , but in my case around 10% of total volume.
To summarize: Think twice before buy from Massdrop this unit.
For Massdrop I want to see legislation for selling product without warranty.
Thanks for the heads up. Same as the Topping DX7s. Wanted to purchase from Massdrop but had not warranty so bought it from china with 1 Year Warranty and end up paying the same.... Now using it as I type with a LOXJIE P20 also in balanced mode. Fantastic. Not everything is worth to purchase from Massdrop...
How can I return su 8,
Order placed with the vendor
ESTIMATED SHIP DATE

Better to contact Drop support team.
They will cancel your order before the shipment.
After 8 months I have finally manged to send it back for repairing to SMSL China.
general rule of online purchases - warranty starts when item is delivered, not when shipped.
Thanks for mentioned it. Any way Drop refused to do RMA. Have contacted directly to SMSL and they did unit replacement. All issues are gone. I took me around 1 year. Not a bad DAC. But now I am using Topping DX7 more as it has coax output, which after goes to 7 output coax splitter, and after to all my gears. Regards, Kim
