Here are the components of my system:
VPI Aries II w/ JWM 10 arm, Dynavector Karat 17D2 MkII
K&K Audio phono preamp
Levinson 37 transport (upgraded by Joseph Chow)
Audio Horizons TD 3.0 DAC
Audio Horizons TP 2.0 preamp
VTL Signature MB185 monoblocks
Audio Horizons interconnects, power cord and speaker cable
In my previous suggestion about a search, I failed to consider that you asked about speaker cables particularly. The speaker cables are particularly well insulated and damped in a way that prevents the noise from mechanical vibration that masks low level detail. Before using them, I was unaware of the effect of mechanical wire vibration due to the electrical signal that was being transmitted over the wire. These speaker wires deliver music that is tonally balanced and filled with low level detail.
