I calibrated the Benchmark so that when going out at -6dBFS I get my standard (classical music) monitoring level (as described by the K-system standard).
This way I can still boost playback volume, I can switch to K14 in a moment, and at normal levels playback is 23 bit.
I prefer this tradeoff to the impact the volume pot has on stage width and depth. I go straight into a 3BSST and Link K50 speakers, when I switch in the passive pot the image just shrinks by 30%.
IMO if the Bench sounds loose in the bass, or veiled in the highs, that means the recording or playback chain is. In our setup it sounds tight, quick, open, very listenable (before we got the DAC1 it was hard to really keep listening during long days), and it will pass on any little detail or change in the recording. It will NOT throw it at you, as it doesn't hype anything.
