Phil --
I'm not personally familiar with the 67SE, but I'd say that you should DEFINITELY bypass the DC-1. I have a DC-1/S9000ES combo, and I get much better results not using the Lexicon for 2-channel playback.
What I did is to use the 9000ES's internal DACs (which are pretty good) and send its analog output to a Channel Islands VPC-1 passive preamp ($220 new), then feed that to the amplifier. The nice thing about the passive preamp is that it's simple to integrate with the Lexicon for HT playback -- just turn the volume on the VPC-1 up the whole way, and it disappears from the signal chain, allowing the Lex to drive all the volume just the way it should. The VPC-1 has two inputs (one for the 9000ES, one for the L/R main outputs from the Lexicon). If you have more than one 2-channel source, though, you'll need a preamp with more inputs.
