If you didnt think much of the Laney VH100R, then the DSL will seem like a tonal shite heap. I swapped from one to another, I would have to reccommend getting all of the amps up to normal playin volume to really test them. I find that the closest you can get to fender (and better) cleans (other than a fender) is Hiwatt 100 watt custom classic head (but one channel and over £1000), a Matamp again usually over £1000, probably a rivera too as rivera designed all the red-knob fenders from the 70s/80s (i think it was then anyway) and I think that my Laney VH100R sounds just as good as anyfender clean, but I play a strat, so clean tones are always better than a Humbucker guitar hehehe.
Also, some of the other mesa's you find around the joint sound awesome, some of their combos are just amazing, Rectumfriers (deliberate spelling) are just overateded.
Finally, have you tried finding a perfect clean amp and getting a great distortion pedal?
