what do you need the cable to do?
off the bat I wouldnt classify mogami anywhere NEAR the canare star quad in so far as strength is concerned. A camera dolly will slice mogami in a second, where you can run over star quad with an operator, an assistant and a panavision all riding... Mogami is also a lot harder to wrap quickly because of the softer rubber jacket. The braided shield on the star quad also offers a much higher degree of RF rejection than the mogami which has a twisted shield. Mogami sounds much better than canare though, much better. The only reason to use the star over the mogami is for all the durability issues I just mentioned. It has a much much softer high end (read roll off) than the mogami. Mogami has a copper drain wire also, so its much faster to wire up. It sounds good and is durable enough to sit on the floor of a recording studio with no problem. Redco.com makes a copy of the mogami wire and on my bench I cant tell the clippings apart, its half the price and its available 12 months out of the year, mogami can be often times difficult to get. I did the entire install for my studio with the redco TGS and it absolutely rules. Best value out there by far.
In the end Id use either the canare or the redco, but they are very application specific. I have tons of star quad cables in my studio which are overflow from my location package and they rarely get used in the studio. If you dont compare the two, you'll never ever for a second think the canare sounds bad, its great cable. When you start doing comparisons though, the high end on the mogami is more open, the TGS is just lower capacitence cable.
