Whenever I do an A/B with the DSL15 against the DSL20, holding all variables other than the amp constant, I always end up preferring the DSL15 on recordings because it sounds tighter and more mid focused. Another way I would describe it is, stiffer and drier. As for what might account for the difference, I recalled that Marshall describes the DSL15 as having "a high-gain, mid-boosted tone based on a hot-rodded JCM800 2203." Because "mid-boosted tone" sounded a lot like a TS9 to me, I decided to put a TS9 as a clean boost in front of the DSL20. The result was that the amps sounded near identical. Obviously, due to the TS9, the DSL20 sounded a bit livelier, with maybe just a touch more saturation and gain, but the midrange and low end definition were almost the same. Personally, I thought the DSL15 sounded a bit more natural (less metallic and aggressive) in the low end, but the difference could also be used to create subtle contrast in recordings. So, if you have a DSL15, I think that amp is already good to go as is. The DSL20, however, needs a boost, in my opinion. Without the boost, it is too fizzy and tubby, in my opinion. But, then again, that might be just what is needed for certain styles and applications. It's all about knowing the gear well, and using it deliberately to achieve the desired result.
