I thought the bit perfect only worked in KS mode. What modes are currently supporting bit perfect under Windows Vista/7? up to 24/192?
I got one of those (the model USD). It does playback 192/24 and with fairly low jitter measured on an AP SYS-2722. *I know* it is not the best tool to do the measurement so please don't start on that. The jitter spectrum is purely white noise in the audio frequency range, although the "noise floor" is about 20dB higher than the AP digital generator looped-back. It is overall quite well designed, using DCM inside the FPGA to generate audio clock from the 24MHz EZUSB system clock. The down side - the coaxial outputs is a bust - transformers not really rated for 192k and an output level only about 57% of what it supposed to be when loaded with a 75 ohm load. |

The monitor 01usd sounds a bit bright in the treble and not as natural pitch wise. I guess the monitor 01usd might take longer to run in due to usb power rather than mains ? |
