I did have a Trace GP12SMX with TE 4x10 & 1x15 and its definitely the combination that gets you there. I replaced one of the TE cabs with an Orange 4x10 and it sounded good but didn't sound like a Trace amp any more. It was closer to the Trace sound with my Orange head with the Trace cabs.
I think the TE reputation for being rather weighty is exaggerated. The TE 4x10 is the same weight as my Orange 4x10.
