Another thought - does the TACT have a digital output? If so, try recording it playing that 1kHz square wave using a soundcard digital input. That will give you a file which has never been in the analogue domain and hence cannot be affected by jitter (unless it's so bad it's causing bit errors,

The poster above mentioned that the DacMagic does not do input switching. This is wrong. There are three switchable inputs. One USB and two that have both S/PDIF and Toslink connections. What you can not do is connect to both the S/PDIF and Toslink connection on the same input. -- rwortman
