Hello,
I did exactly that.
Back when DAC's were 8-bit devices with current output.
I took a transimpedance device (metal film resistor) and changed current output to voltage output to the input of a single end 6DJ8 dual triode. That was the best sounding DAC in town.
For $900 I will dig it out of the cage and send it to you if you like.
Thanks DT

Sounds like we both go back to early days of DIY for car 'stereo'.
6DJ8 (even w/a cage) is not a good deal @$900 but a J29/DB (w/a cage) most definitely would be!
Thanx for the offer but after about a dozen successful car audio surgeries, I'm now retired!

Did anyone find out what the output impedance is?
SMSL is going nuts. Now besides the SU-9 pro with the dual ES9039MPro chips at $499, they just released the D400ES with a single ES9039MSPro at $799, and the D400EX, which has the new AK4191+AK4499EX combo at $959.
The only practical difference I can see between the SU-9 Pro and the D400ES is the addition of several other inputs, such as IIS and AES. Interestingly SMSL is the first manufacturer to offer both new flagship DAC chips from ESS and AKM. Whether they offer anything above what we already have with this SU-10, remains beyond my imagination. What’s to improve?

Some Jeep SUVs can have an upgrade for McIntosh audio now.. https://www.mcintoshlabs.com/automotive/the-vehicles
Must be the manufacturer’s communication error?

Another difference between the SU-9 pro and the D400ES (of unclear significance) is that the SU-9 Pro purports to use the ES9039MPro chip, while the D400ES uses an ES9039MSPro chip. I have no idea what the difference is between the 9039MPro and the 9039MSPro. Any ideas?
In my opinion, the difference is in MQA. One decodes the other does not.
I second this, @amirm.
Is this the same as the one linked here?

No. According to your link - the old firmware (SU10_1v01_b2). My link with the new latest firmware (SU10_1v02_b1).

Still pretty new to this site so apologies if this is covered elsewhere and I haven't found it yet but when this unit gets a SINAD score of 123.8 is it fair to say the unit is 0.2% better than the Topping DX7 Pro+ at 123.5? It would then follow that the SU-10 is 3% better than the DO100. In the "real world" what difference in the SINAD score translates into something audible and how dependent is that on the equipment I have? Is this also dependent on equipment, for instance, it might be audible with $20k worth of equipment but not $5k worth or inaudible in an untreated room but noticeable in a "perfectly" treated studio.
In case it is unclear I love this site and using measurements to evaluate audio equipment and I have Topping DAC that I purchased because of this site. I'm just trying to figure out how to make real world purchase decisions. Of course I want the latest and greatest gadget that has eked out 0.2% of an improvement but does the unit that costs half the price deliver the "same" sound out of my less than perfect system in my very less than perfect room?

Then buy a less expensive DAC if you are concerned about your room. Just kidding...
Are you using EQ/PEQ?No not using EQ/PEQ yet but that is tangential to my question. To put it another way if I had EQ/PEQ could I detect a 0.2% difference in SINAD?Then buy a less expensive DAC if you are concerned about your room. Just kidding...
