Benchmark DAC-1 Pre vs Parasound JC-2

Please forgive the repeated posts about the Benchmark. I am trying to decide between the above two from a preamp point of view. While reviews would seem to favor the JC2, it seems that the Benchmark circuit is so simple that the chance of introducing sonic anomalies should be low.

I will only have one source (Sony SCD-XA5400ES) and it would be interesting using the Benchmark as both a linestage with balanced ICs and using it as a DAC.

Has anyone had the chance to do a comparo?

Thanks!
