The Audio Refinement is simply an analogue preamp with a six channel analogue bypass input. There is no signal processing; ie, not even dolby pro logic. An external digital processor is required unless this preamp is only going to be used in conjunction with DVD Audio and/or SACD. This approach is not that useful with the plethora of high quality preamp/processors available with 5.1 and 7.1 analogue bypass inputs.
The Audio Refinement Pre2 DSP is a possibility. It, however, does not have dolby pro logic II. I have chatted with a couple of owners who like their Pre2 DSP products very much, though.
