Anyone?

It seems, AQ Volcano is replace by AQ Oak. Retail price wise, they are similar as well as their wire structure being all PSC+. AQ used to provide more details about their cables like AQ Volcano, but for some reason they stopped doing as such.

There is also, AQ Comet (almost same cost) but this one uses 1/4 silver PSS and 3/4 psc+.

I have a pair of AQ Volcano which is a much thicker cable compared to AQ Oak and AQ Meteor (that I use on my primary setup), perhaps because of its higher no.of RFI insulation layers.

hope that would help.
cheers.

Wire sizing, ie differing gauges and overall combined gauge looks the same as oak, good call michaelzay.  I had Oak with Colorados for quite a while and can say it certainly did NOT suck!
