Anyone know of a list or guide somwehere that highlights special features of equipment that enables new functional capability?
For example, the Topping D10/D10s has digital to digital conversion in addition to powering its own RCA. The BTA30 can do LDAC over TX, and can upsample in RX mode. Maybe there is an amp with independant rear-out switch and volume control. Or has multiple analog input with a button switch. These sort of stuff.
If you know of something with special functions, do mention.
