Just my opinion of course but the CPT 300 due to its size and balanced nature is best suited for multiple components. Giving all that is plugged into it the benefit of balanced power. The Graphene cables are best suited for the individual components. I own and really like both cable brands.
Buying all CPT cables for the individual components really would add up the $$$ and you would have a huge pile of balanced transformer boxes.
Bacardi, the price for the Graphene Extreme doesn’t just double when the length is doubled. But, I bought mine early on (about $300 for 5 foot) so I’m not sure of the actual current pricing. Also comparing the CPT 150 which has only a 150 watt capacity is not in the same league as the Cerious Technologies Graphene Extreme which use much larger conductors in their design and would power much more than 300 Watts. The CPT 300 would seem to make sense for comparison pricing. The CPT 300 5 footer costs $850.
My point was for all to keep the prices of the individual cords used in the forth coming shoot outs in perspective.
