I haven't tried Transparent but have tried two NBS single-ended cables: King Serpent II and Signature II. Both have a big mid-bass amd a top end which may be a little too bright on some recordings. The Signature in particular has a beautiful midrange. Vocals are to die for. The Signature ever so slightly bright in the upper mids but if this is there, I would say it adds an "aliveness" to the music rather than calling it a fault. The Signature also conveys better than any other cable I've tried, the transparency, detail, soundstage and ambient information in which the recording was made. The King Serpent II, while quite similar to the Signature II in frequency balance, does not do as good a job with soundstage or ambient information and I would rate it well below the Signature II. Overall, I would say that the Signature II is the best interconnect that I have ever heard, although I haven't auditioned that many "expensive" cables. I haven't heard any of the Monitor series. My experience with these two cables makes me feel cautious about extrapolating these experiences to the sound of the Monitor series.
