Well, it's been about nine months since Fosi's announcement regarding the "form factor" for a multi-channel DAC and we have heard nothing, nada, no news or announcements or (gasp) a product to show for it. At this point, who really cares about the "form factor".
@Fosi Audio : Build and sell the DAC already! I could care less if it has a remote control, a knob, settings/adjustments, or multiple anti-aliasing filter options.
I want a box with the following on the back:
1. A USB connection (don't care if it is B or C type)
2. Eight (ten would be even better!) TRS balanced outputs
3. AC input using an IEC receptacle and a built-in, universal voltage power supply
On the front:
LED display showing sample rate for WAV or DSD (if supported)
Power switch
Other performance related issues:
Please design the output stage so that people who use unbalanced interconnects (e.g that typically need RCA jacks) can use a simple TS-->RCA adapter jack in each TRS output without a big performance penalty. This has been a problem with other gear and the solution is really not all that complicated! Add one more output amplifier (discrete can also work here) stage after the DAC circuitry, drive only the HOT pin with signal, and make sure the impedances of (+) and (-) lines are as similar as possible (e.g. 0.1% or better matching). This is called a "Pseudo-Balanced Topology". Practically no one needs both hot and cold lines actively driven. This "feature" will make many customers happy and the product can work for a wide variety of users.
