Lovely looking preamp - expensive - how would you characterize it's sound (if it imparts any to the source signal)?
Hard to say... This linestage just sound right with any amplifier I tried with it. To be honest, you would need to try the unit in your own system to be able to answer you question.
Here is a description by Martin De Wolf of Bound for Sound that represent the way I feel about this linestage and it pretty much dead on from my personal experience with it:
"With this preamp what you will hear is a resolution floor as natural and undefiled as music itself. Be it from an FM tuner, reel to reel, or a sophisticated analog/digital front end, five minutes into any listening session will have you hearing, for the first time I think, what seems like the totality of the music. At the micro level of the resolution music spectrum, the Purity Reference reveals shadings, nuance and inner reflections that are common to everyday sounds but seldom, if ever, heard in reproduced music."acadie
