I have used the OCOS in my system with great success. I use a pair of Watts & Puppies with a pair of BAT VK-60 or the new (fantastic) Analog-Research Technology digital switching amp, a ruthlessly revealing amp. In both cases, as it is the case with Dgordonl s system, the sound is excellent. I originally used a pair of expensive MIT CVTwell it was expensive until many other megabuck wires came alongrecommended for the Watts & Puppies and was pretty happy with this combination. But when I switched to the OCOS, lo and behold, there was an ear-opening experience. A veil was lifted. The highs became cleaner and more detailed. The muddiness in the midrange was gone and the tubby bass became considerably faster and tighter.
As Dc2daylight correctly stated, you should use at least a double run of the OCOSat the price you can easily afford it. I move from single to double, triple, and quadruple runheck Id try anything at that priceand found an optimum with the triple run. And, by the way, I use the red couplers. Note: if you use multiple runs, make sure to combine the + and wires into two single spade lugs.
There isnt any doubt that there are interactions between the amp, speaker wires, and speakers. I am not an electrical engineer but I understand that it is a matter of load, which is frequency dependent. Your speakers present to the amp different impedances at different frequencies. And each amp reacts differently to this changing load, which in turns affects its frequency response. The speaker wires are part of these interactions and will definitely affect the sound differently depending on the amp/speakers combination. The word synergistic effect is often used to gloss over real technical explanations which many of usmyself includeddo not really understand or do not care to know, which is fine.
In my system, the OCOS triple runs clearly trounce the MIT CVT Hose, the Straight Wire Maestro (SP?) and the Cardas Golden Reference. Which reminds me that I still have those wire stashed away somewhere that I should sell off.
