Re: What's warmer..an UO Roughcast A5 or a Roughcast A2?
Both have a smoother high-end than the equivalent polished mags, but the RC A2 will have less high-end and more mids than a RC A5. If you have a polished A5 and want to take off a little treble and harshness, try a RC A5. If you still need more mids and less treble, you can try an A4, RC A4, A8, UOA5, A2, or RC A2 (in order of increasing warmth, at least to my ears).
