Having tried everyone of the new range of Matamp cabs (and owning most of them)
They do lean to the more vintage side of things but not in muffled way that most people associate with vintage.
The 8x10 is flat out better than every Ampeg 8x10 I've tried, louder, clearer, fatter etc etc.
6x10 is a very sparkly cab, lots of high end, suits the more clicky pick players amongst us but still very full sounding and very loud.
4x10 depends on the speakers you get I have a ported cab with some heavy eminence speakers and it's very aggressive sounding, most of the instock cabs are sealed with neos these are much more polite but again very full sounding, a friend of mine use to use 2 of them when playing a lot of Motown covers
2x12 again depends if you get the neo or heavy weight very, the neo is usually in stock and this is the one I own. The heavy weight version has more bass but weights near double the neo 2x12. It's a great cab and when I can't be bothered taking my 8x10 I take this and it's more than enough for a very loud rock band (if we weren't loud I wouldn't need an 8x10 would I?). This cab is a bit more refined than the 4x10, certainly a lot more polite than the ported 4x10.
Now I've not tried any of the Berg stuff, I was actually going to buy the NV610 and NV215 when I ent to Matamp on the off chance that they could make something for me (they didn't have the range they do now of bass cabs) and they made me the first 8x10 and new style 4x10 and I was just blown away and I haven't liked another cab since.
What I will say is the build quality is way higher than what you'll get from companies like Ampeg, Ashdown etc.
Hope this helps, they do, do other cabs as well but not sure if you've be interested in those 2x15, 1x18, 1x12 etc> I'm getting the 1x18 soon as it has internal cross overs so then my 4x10 will be just for mids and treble, sounds amazing smooth across the full range.
