Hi Mrtennis,
I agree. Personally I only ever used the medea in FireWire mode with Amarra direct into various amps. The zanden adds to digital what my Yamamoto adds to the Medeas über clean untouched approach IMHO.
Personally I want my audio untouched. But obviously this means the synergy between the system needs to be finely tuned.
Argyro,
I felt the Vekian had nowhere near the openness in the treble or anywhere near the transparency & lack of grain of the Medea.
Again I agree with you that each of the above mentioned products balance is completely differently if used with preamps or without, or with transports or computers etc.
As always set up is everything. I found the Medea plus to be utterly true to the source (with FireWire). That's why I find it the best DAC I know. If you want editorialized signal then you need to look elsewhere.
