I haven't tried the BC Silver Serpent, but tried one of their earlier models and did not like it. I have owned both the new and the older Apogee in both the rca and the balanced versions. I used to think it was one of the best values around until I recently tried Phoenix Gold DR.910 which I think is a little clearer and smoother and it costs less! I also like Harmonic Tech Copper Link but it is more expensive.
