I have done the bit perfect test on a few of the active extenders. Bit perfect. I've got one I use that is 15 meters, and have used them at 25 meters. No problems. These do drop voltage just a bit. That is why if the DAC is USB powered it might have issues, but for signal transmission works for DACs, printers, etc etc.I linked the 20m version above which has 2 signal amplifiers, but I'm really curious about how is the data transmission over this distance. Best would be to verify the digital output of the DAC via an optical input board and compare for bit perfectness.
Another option if the DAC has coax SPDIF is to use one of the good USB to SPDIF converters (Douk Audio U2) and then use some RG59 or RG6 cable to the DAC. I think coax digital is good to 100 feet or maybe it was 100 meters.
