So it seems the KTB is not actually doing hardware VC even though it says it should or am I getting something wrong here? I am actually not concerned about DSD.
No, all the VC wonkiness we are talking about involves playback of DSD tracks.
As I said, with PCM-encoded tracks (e.g., the usual .wav, ,aac, .mp3, .flac, .ogg, etc) hardware VC seems to be working just fine.
As for the 100 percent volume issue, it is a characteristic of DSD that the bitstream cannot be modified upstream of the DAC. This means no software control and the output will be at 100 percent unless the DAC has some sort of volume control mechanism built into it. The ESS chip supposedly does but AFAICT it's not exercised through the XMOS interface.
Quote:Since I want to use it without a preamp I would probably steer clear of it then. Maybe I should just go for a dac with a regular old volume control knob on it.
I'm always nervous about directly driving a power amp but that's just me.
