I already bought my coupling caps and impatiently waiting for the unit.

I haven't yet.

I owned the MK2 version of that preamp, but sold it just two months ago in anticipation of the MK3 version. I placed an order for the MK3 last week, I am now waiting impatiently for it. My previous version had the Mundorf MCAP supreme silver gold oil for the coupling caps, this time I'll try the...

Êtes-vous familier avec le site audiosciencereview.com? Ils ont fait des tests là-dessus, et n'ont trouvé que ces interfaces ne dégradent, ni n'améliorent le signal USB en provenance du DAC.

C'est quoi l'utilité de l'interface USB (Le gustard U18), n'est-ce pas un gaspillage d'argent?

To FIIO: Would you be interested to trading my M17 for one of your R9? I never really used the M17 in a portable manner, I always use it as a desktop unit, therefore, I think the R9 is more appropriate for me.

A few other things that are worth mentioning - I have set the DC/BAT switch to DC, and I have disabled battery charging when the unit is in the ON state. Battery charging only takes place in the OFF state. I set the maximum charge for the battery to 90%. I very rarely used the unit on battery.

Always.

Interesting! Although I always remember to turn on the fan most of the times when I am using my unit, but some rare times I forgot, but never had any heat/battery related issue. My listening volume is set to 80 when using my Sennheiser HD800S, and 50 when using my FIIO FH9. The fan is always set...

I currently have the M17 and only using it explicitly as a desktop unit, never took it anywhere, therefore this unit is a perfect replacement for my M17, but I won 't be buying one since it is not using the latest ESS9039PRO chips. I don't want to buy now, since possibly the ES9039pro version is...

SMSL SU-X, the competitor of the Topping D90 III. Basically the same thing in different casing. https://shenzhenaudio.com/collections/new-arrivals/products/s-m-s-l-sux-dual-es9039mspro-digital-to-analog-convertor-dac

Wondering then, why wasn't the same logic applied to the D70 line, since the new D70 doesn't resemble anything like the old one. I am not getting it either to why is it ok for the flagship unit to look worst than pretty much all of the lower tier units in Topping's DAC lineups.

Look-wise, I was expecting the same design philosophy as the DX9. I don't use MQA, and never would, therefore, I don't see myself paying for needless stuff. Why Bluetooth 5.1 and not 5.3? even my cheap $200 projector has Bluetooth 5.2. $900? Really? What was Topping thinking?

I owned two of the MP-D2 MK3 Deluxe units, sold both last year to buy the FIIO M17, now I I need a desktop DAC again, this unit may be it. Hopefully, the pre-amp section of this version will be good enough so that one won't need an extra pre-amp.

Are you sure you also don't need a new stand, a new case, as long as in your mind, like some have been blurting out here -- may contribute to a more impactful, magnificent, ect...as limited by your imagination.

It is obvious to my ears and my system that both of my dual chip DACs provide better dynamics and channel separation than my single chip DAC. Why did FIIO and other manufacturers like Gustard and now SMSL with their new U10 took their time to use dual chips if they didn't think that it adds...

The Topping single ESS D90s measures slightly better than the Gustard, yet the Gustard sounds better than it. I have both the Topping D90 and my FIIO M17 connected to the same tupe balanced preamp/amp combo driving a pair of Klipschorns, to my ears, the M17 gives a fuller more musical sound than...

What I would love is a product that shares the exact same features, specs and sound signature as the M17, but without the screen, that powerful CPU and Android OS. Meaning I would like it to have dual ES9038PRO, onboard storage for audio files, capability to access this storage and play these...

As a retired System/Electrical Engineer, I take offense of your statement that the power cable makes a very significant performance gain.

If the amp is not used, how does the device generate that high output signal level in balanced line out mode? If this EOA feature is not used when the device is in DAC -> line out mode, then why are we given the option at all to enable it in this mode? You see, that's the mode that I mostly...

Questions: 1. Is the enhanced over the Ear mode needed in DAC mode? If not then, why is the option to enable exist when I connect DC power in DAC mode? 2. Per Fiio's M17 documentation, the device can support up to DSD256 with the on-board SOC, but why then the all DSD feature/option is limited...

Frankly, I wouldn't mind a bigger unit in order to fit a big heatsink in. anyone buying this unit does not care about the size or weight, I personally needed a somewhat portable unit that I can use both at home as a desktop DAC or DAP, and in my car as a DAP; the M17 fits the bill, but that...

May be there is an application running in the background causing this issue, try upgrading it with the M17 in pure music mode.

I have updated mine without any issue. Are you updating in android mode or pure music mode? I have done mine in pure music mode with no issue at all.
