Hi Mark, you are correct... Criterion was by far my reference preamplifier, and would still be my reference if I had a mixture of digital and analog sources.
But, as I use only digital sources.... and only one of them at that, Criterion was wasted... I now go directly from the wonderful Rowland Aeris DAC into the Rowland M925 monoblocks. The sound is fabulously resolving, fluid and immersive, and intensely lyrical... And the system is absolutely without any background noise what so ever.
