SMSL ( S.M.S.L ) DO300 DAC

[Burns]

I bought SMSL DO300 and I think I became its beta tester.

- The device in the factory settings is +2dB by default,
- the default filter is fast linear, but more importantly, when the filters are turned off, the volume increases drastically and the sound becomes hoarse (Is there jitter mismatch? )
- The device does not have factory measurements,
- you can see and feel that someone was in a hurry to create this device,
- Device needs updating? I wonder when will the update be? I wonder if the update will solve all the problems, or maybe the device is poorly constructed?

A lot of questions and unknowns until the manufacturer measures it and even better if it was measured by Amir.

I know what I am writing about because I had DO200 mk2 before and I did not notice such problems there, but the device has been on the market longer and had the mk1 version.

Won't it be that the +2dB volume is set on the 5/2.5V outputs and the 0.0dB is set on the 4/2V outputs when we set it only in DAC mode, thus blocking the volume change?

If so, this is a very strange implementation.

I'll talk to myself then. Perhaps the implementation overlaps with another device on the same chip.

SMSL D400ES DAC Review

This is a review and detailed measurements of the SMSL D400ES Balanced Stereo DAC with Bluetooth support. It was sent to me by the company and costs US $800. The D400ES is quite stylish especially if you look at it an angle where it exposes the black heatsinks. Alas, the rotary control is not...

Nothing much to talk about without professional measurements

Nothing much to talk about without professional measurements

I read all the comments in the above thread and it looks to me like the same magic when the filter is turned off.
The volume is lowered with the filters what I also hear. I don't need to be certified to understand that probably the factory default value for DAC only mode set to +2.0dB sets the voltage to 5.2V and a setting of 0.0dB will reduce it to 4.2V. In the Topping e70, the voltage is set in the "BIOS" menu. Weirdly came up with SMSL, by the way. Of course, I'm waiting for professional measurements, but I don't expect miracles, possibly nuances ...

I use the +2.0 setting. Fast linear and standard sound color and it’s cloud nine for me (in comparison to my pre/pro dac).

I’m not sure if someone was in a hurry but if they were this applies to all their DACs that use the new 9039 DAC. I’m listening to music right now and it’s just audio bliss.
