Thanks for the suggestions.
Currently I'm using my D7 for a while for this purpose. The problem is, I'll also have to eventually hook it to my DAC, in order to transfer the tapes to PC. That's where the upgrade becomes necessary.
In the meantime of using the D7, could anybody suggest me a way to avoid changing cables on my DAC everytime I want to hook my D7 to it ? Will an A/B switch do the job ? Or should I be looking for an extension (Toslink) cable ? Both possibilities sound not as good to me, though my experience with Toslink is very limited.
Thanks
