Great to see them fixing broken designs and actually caring about performance.

SMSL SU-8 Version 2 Balanced DAC
- Thread starter amirm
- Start date
HMM, I think Amirm's unit on the right is V2(V1.2). My Unit on the left is V1 (V1.0) Thank you for the comparison!

I bought a su-8 at 11.11, the price is about $158 (1099 rmb). I didn't know if they had corrected this problem, so after two days I returned it back...
then I bought a topping d10 and a khadas tone board
now I little regret, I like balance out

Something we have changed.
In order to prevent my translation errors, I will keep the Chinese that the engineer told here.Thanks.
输出端这三个开关的供电，由原来的5V提高在9V供电而已，其它在无更改。我们再说明一下，他之前测试时是因为他们测试方式都是以0dB频率信号进行测试的，之上一版本机器就后面开关供电的电压幅度不够所以看起来参数会差一点，但上版本的机器以-6dB频率信号进行测试，参数也会是很好的，当时设计人员认为用户正常使用播放歌曲信号，是不会有0dB频率信号那么高的幅值的，而且这个机器是有前级功能。
还有就是一个多余的时钟没用，删了，加了一个备用的保险丝。这些都不会影响参数的。
The power supply of these three switches at the output is increased by the original 5V to 9V, nothing other have changed.
Because all tested with a 0dB frequency signal. In the previous version of the machine, the voltage of the power supply behind the switch is not enough, so it seems that the parameters will be a little worse. But if tested with a -6dB frequency signal, and the parameters would be very good,too. When we designed SU-8, the designer thought that the normal user would not have the same high amplitude as the 0dB frequency signal, and the machine is pre-AMP.
An extra clock is useless, deleted, and a spare fuse is added.These do not affect the parameters.

I think that is probably the reason, just like how the DX7 isn't even in the list

Version 1.1 from me, bought around one week ago.
Question now is: Should I try to get a refund or exchange it with a v1.2 unit? Bought it through Amazon and I can refund it.

I have board version 1.1, I see v.1.0 and v.1.2 mentioned here, were any improvements made from 1.0 to 1.1?
Did you not buy the GALA dac? Cold feet on that one?
I guess you can ask Amazon support what to do.

BTW: Really great to see that SMSL is active here and improving the SU-8 with the data Amir is providing.

The price with 189€ was just too good and I realized that I always could resell it for this price.
Funding for the GALA is also not going well...
Edit: Given the really easy nature of disassembly/reassembly, the most efficient and environmental friendly way would be to send out new boards. As far as I can see, you don't have to solder anything. Just unscrew a little bit and exchange the board.

I think its neck and neck but the DX7s has features like a possible remote and a built in Amp.
