No reason to "upgrade" from Stratus Golds. They do so much right, and are resolving enough to yield audible benefits with disproportionately priced upgrades upstream.
My main speakers are also big floorstanding Canadians from the same era--Mirage M5si's. They anchor the 7.1 ch HT/surround system. I still marvel at how *right* they sound, and the Stratus Golds have a similar, natural tonal balance, but with an even more transparent midrange. I think you'd have to spend $5000 to get more than a lateral move from your Golds, and even then you'd have to choose from a value-leading manufacturer such as, oh, PSB.
