Well, thank you all very much for adding to this thread, but I am just so confused that I dont think I will be buying anything any time soon. I understand that I may not find the perfect amp first try, but I really don't have the luxury of being able to spend $1500AU+ on an amp that im not sure of.
Carvin, Ashdown, Randall, Crate ect.. are all brands that I have heard great things of, but I wont be getting unfortunately, because I cannot find anywhere locally that keeps stock of them (or in the case of crate, they only have the huge stacks). I emailed the only Carvin dealer I could find listed for Australia (3 states away) on the price for the 2x12 all tube carvin combo that has generally good reviews, and the price was pretty good $1600AU, but once again... I cant test it for myself so I would be a bit silly to go out and buy it based on some good reviews.
Right now, if I get anything, it will probably be the Marshall TSL602 or the Marshall TSL122. Unfortunately I haven't heard those either, however I have heard the TSL 100watt head through a 2x12 stack and it sounded almost as nice as it did through the full 4x12 cabinet, so even though I doubt the speakers in the combo would be as good, I would be willing to take a little leap of faith there i think.
Problem is, on Harmony Central, as always, there is a large diversity in responses for the TSL series, with a few really scathing reviews saying the speakers are horrible and it is not durable at all...
Oh, and sepultura, as far as musical style goes, sorry for not clarifying that. I play metal primarily... anything from maiden to shadows fall. But I also pitch in on the guitar for a covers band, so that requires a bit of diversity, but never strays too far from your average rock tunes. I like mucking around with blues tones from my strat, however I wouldnt consider that a huge priorety...
