Haven't heard them but wonder about cable recommendations. Spectral demands their components be used with MIT, or else the warranty is void, I strongly suspect due to bandwidth limiting so the components do not go into oscillation.
On the other hand I have some audio cables capable of transmitting hi-def video (74 MHz) without phase shift.
