There is no such thing as “no loss” in electronics. With each interface, there is a distortion added which is called “jitter”. Don’t think the data stream as one set of binary numbers flowing. There is a whole bunch of binary numbers flowing at different frequency bands. In essence, digital is analog as well. Digital is lossless and logic only during while it remains in the fpga and memory. When it flows between different interfaces(hdmi, spdif and bunch of other internal components, it is a number a electrical impulses (hence analog). Yes the voltage between logic low and high are well apart so 1 and 0 are easily distinguished however the speed, when the data stream begins and end are still bound to the laws of physics. Each cable, even an inch long interface cable will introduce jitter. Is2 to hdmi conversion will introduce jitter, hdmi to coax conversion will introduce another. These jitter will be even greater if the components aren’t selected carefully and clocks used aren’t very accurate. As with any electronics, clean power will help reduce jitter. Dvdo edge has a cheap power supply and is a decice aimed for video. I highly doubt it has audiophile gread audio characteristics.
Lumagen radiance uses hdmi chipsets that rated some of the lowest jitter in the industry and the jitter is even more reduced if you upgrade the cheap power supply with a linear supply. I still wouldn’t and don’t run any of my audio signals through my Lumagen units. Audio cables go directly into my preamp/dac.
