SMSL DL200 the best ever value DAC/AMP?

[csuti]

If you mean whether you can control the hardware volume from the USB host, no, that option has not appeared.

Yes, that was my question! Thank you for your answer!

Can anyone tell me if the front knob on the DL200 can control the volume of the TRS balanced L+R outputs on the back of the unit?

Thanks

Yes, the front knob of the DL200 controls the volume of the RCA and TRS outputs.

Thanks for that. I have one coming in today and was hoping that was the case. I need to control volume going to my "full power" amp+JBLs. I assume any DAC or headphone amp with "preamp" features can do this, but it's good to know the SMSL won't blow out my speakers intentionally (fingers crossed)

Remember to set volume to 00 which is mute before you first play anything and increase it to find the right volume setting. It defaults to 99 which is full volume.

Hi. A new c200pro has been released, it looks like the same dl200, only the case is smaller.

I have received a SMSL DL200 DAC, and put it through some REW, COSMOS ADCiso, E1DA LPF tests.
In my sample the 2. harmonic varies at least 5 dB between the hot and cold outputs on balanced out.
Then the 2. harmonic is not possible to cancel by balanceing circuit in ADC.
Is it possible to adjust the distortion by adjusting the adjustmable resistors marked with yellow?
Looks like in my sample, the harmonic distortion in last 10 dB is dominated by analog circuit. (The harmonic components at -120 to -125 dBFS)
It is by no means bad, but not at -140 dBFS.

Single ended out. Virtual balanced at DAC/REW

Second harmonic

6 hours stepped. Bal out

 

[torgeirs]

Well, if someone knows about the adjustable resistors it would be interesting, but I guess I will not fiddle.
Just have to stick to 44.1 kHz sampling frequency or multipples of that to get superlow 2.nd

So DAC clearly optimized for X * 44,1kHz, Analog buffer is fine!

 

[torgeirs]

stepped, TRS out, 10 V ADCiso. 60dB 0,1 dB step. Pretty Nice

20 to 20k full volume

 

[torgeirs]

Stepped 88,2 kHz

What am I looking at here?

 

[torgeirs]

SMSL DL200 DAC into COSMOS ADCiso. Measuring with REW.
It is harmonic distortion and noise versus output level.
When using only 0.1 dB volume steps we can see the distortion variation. That indicates where it is just noise and where there are rise in distortion.
Can be useful if the user want to apply digital volume control.
The sweetspot of low distortion can be found

 

[torgeirs]

It is also kind of the distortion signature.
But in my opinion to low to be a sonic signature.

 

[torgeirs]

For post 1251 the distortion of the ADC will also come into the picture in the last decibels.
But in my eyes crazy good values for distortion. Both DAC and ADC

The value is pretty good, but the space is competitive even against SMSL's other products.

 

[torgeirs]

Yes. But this combo with ES9039Q2M and MELF resistors are pretty special at the price. If used at n x 44.1. At n x 48kHz its more like the others. And they are more than good enough.

 

[torgeirs]

And if the noise is not heard, the harmonics are under hearing threshold, -80dBr, even at -60dBFS.
So perfect for digital attunation. I use max 40 dB from quiet background up to loud for the neighbours

Sure but so is the DX3Pro which is cheaper. There is alot of competition, like I said.

Still no usb c
