finsup: Thanks for the kind words.
So much comes down to what you value in a speaker, what kind of presentation you like and what your budget is.
As small-ish monitors go, I think the Fritz's are wonderful and well worth considering. I think that the Carbon 7 SE, in particular, is a great all rounder that, as I wrote in my review, was much more compatible with a SET amp than I'd have expected "on paper." I am less inclined to offer a strong opinion on the Carrera as a value proposition because I suspect it would have performed even better with a more powerful amp than I have at my disposal. But there's no question that the Carrera is a classic Fritz product: well built (especially that cabinet!) and fitted with premium drivers, with balanced, non-fatiguing sound and shocking bass extension for the cabinet size.
Yes, I am working within a strict and rather tight budget, which is one reason that the Spatial's impressed me so much. They are quite great regardless of price, but especially for what they cost.
