How weak is my Digital link?

Toslink from the CD player to the DAC, Coax from the DAC to the Pre.

Hey for $30, ill try anything. I guess thats why I smoke pot. ;)

Thanks

Try to find a Cal Delta transport to go with your Sigma
and bag the Toslink for a digital coax or balanced cable.

Once you get a digital inferface you like, bypass the input selector switch on the Sigma.

The Sigma circuit board is very easy to work on, better coupling caps, power supply caps, diodes and resistors will also give you a lot bang for the buck.

Kana,

Thanks.

I'm not sure what you mean with regard to bypassing the input switch, what does that do?

Blueshirt- Bypassing the input selector switch eliminates
a set of contacts in the signal path....ie. the best switch
is no switch.
