Tell me the firmware number on which the error with MAC addresses has been fixed!!!

Which firmware is the problem on?

Can you tell me if Gustard fixed the bug with constantly changing MAC addresses?

The D400 Pro has separate power supply for the digital and analog parts.Two power supplies.The DL 300 is a budget schematic with one power supply unit.

Two chips give slightly better measurements on the charts.The 400EX is an excellent DAC as well as the 400PRO.You can choose either of these two.:L3000:

Yes, the sound has the same signature.Gorgeous clarity and transparency.I didn't notice the difference.I also like the 5 digital Super Slow filter.

I used SMSL D400EX and now SMSL D400 PRO, the sound is almost the same and does not differ.Apparently, two chips are not needed for the AKM DAC to improve the sound. The SMSL D400 PRO also has a chic design and a thicker metal panel with a large informative display.It is also important the...

In EX,ES,PRO-a pair of low-noise switching power supplies.SU has a pair of analog power supplies.

The ES,EX, and PRO models are proprietary SMSL models. Therefore, almost the same schematics-two power supplies, a clock, etc.Different number of chips. The SU model is produced for the distributor shenzhenaudio.This model is simpler - one power supply, a clock. In the 9038 dacs, there are 2...

You're right.:L3000:AKM are more melodic.

:L3000: "I have owned many ESS dacs and only recently have been trying AKM DACS. FWIW after years of Benchmark and other ESS Dacs there's an upper midrange glassy hint to my ears. This went unnoticed for years, and when you take confirmation bias into consideration may not even be happening...

According to the user's review, the D400 PRO, like the D400EX, play more interesting than the D90le from Topping. Apparently, the number of chips in a device with the same line-up does not have a strong difference, except that there is a slight difference in the numbers on the graphs when measuring.

Appeared in black.It looks more stylish.

SMSL forgot to put the installation guide in a file. :)
