So, in conclusion; technically they are equal (ie both are parallel) and will make no difference to amp or speaker which way you connect. However, 2 separate leads give the marginal bonuses of security during a single lead failure, and fewer connections for the signal to pass to the second cab.
Perhaps some modern micro amps are saving space with one output, or saving pennies. Your Trace gave both, just used different sockets for each.
[b]For the OP's amp, just get a speaker lead with XLRs and one with jacks and you can run separate leads. Can tie wrap them together so everyone knows they aren't mic leads etc.[/b]
Note to Stu, presumably the additional XLR on the back of your Hiwatt is not passing the speaker signal as taking that to any sound desk will melt it. (One reason for using different plug/sockets for different purposes).
I think the XLRs were popular then as pas were becoming big, 'professional' things and used XLRs, jacks were for small 'amateur gear'. Alembic and Jaydee even put them on their basses.
When did we stop calling XLRs 'Cannons'?

I've gone with that option! Bought two speaker cables, one XLR and one jack and connected separately. Cheers everyone for there help on this.
