I had my 3As up-graded to sigs a year ago and don't regret it. As noted in the above posts, it had the effect of opening up the whole upper music range, and the soundstage.
But really, over time and as money permits, I'd look to up-grade both. I can say that in a medium sized room that the McCormack DNA-2,1, and .5 all work very well with the 3As and all have a stiff enough power supply to control the bass well at reasonable listening levels. Good Luck. Craig
