I just don't agree. I've heard Orange cabs in a metal and hard-rock context, and they work very well. If the mids are too honky, use the EQ on the amp - that's what it is there for!!
+1 (No one seems to remember that Jim Root uses the Rockerverb 100 and PPC412 for both Slipknot and Stone Sour, sounds good to me)
Its all in the eq.
From my experience and from many clips, even comparing the Recto and the Stiletto cabs most metal guys will say that the Stiletto is boxy and muffled in the low end. I feel that the Recto cab is too scooped in the mids, doesn't have enough warmth and has too much hype in the high mids and as a result sounds harsh.
The thing is, you can always eq out where there is too much of something, you can't boost something that isn't there. With that in mind, being a guy that owns a traditional sized cabinet and a honky as fuck 5150, I am not afraid to grab a post eq and scoop the living shit out of the 200-300Hz area until it sounds natural. Thing is, with the softer and darker high end, you don't have to worry about the harshness of the upper mids when you do scoop the 200-300 area, as when you do scoop that area, the sound does become more focused on the upper mids and if they are foul, you are going to have some problems.
I like soft and dark highs, just enough high mids to have enough presence to cut but not get harsh and enough low mids to sound warm and for that I would recommed the Orange over the Recto. Hell, I would recommend the Stiletto over the Recto too.
