Try turning your presence down to about 3.5 and bumping your bass up just shy of full (on my Ceriatone, it's technically 10 because it goes to 11....). The Delta Pro's are great, but I realized I wasn't really a fan of them despite wanting Joe's tone a few years ago - it just wasn't who I was as a player. I like speakers that add some extra warmth to my sound as opposed to producing what the amp is doing exactly a la 12L's.
As far as selling the Traynor, I recall them selling for about $500 used or so. With that and a little extra cash you could check out the Tweaker, or even the Peavey Windsor head - it's not "boutique" by any standards, but a really decent amp on a budget (we're talking like $200 USD).
I think the 1959SLP's are quite expensive for what they do, and there might be some cheaper alternatives from Ceriatone. I have yet to be impressed by any of the current model Marshall's except the Vintage Moderns which are even a little old now.
What I might recommend is just spending a day going to every guitar store near you and literally playing everything that they have in your price range - I'm very wary of ordering amps without playing them and just going off of what people say. I've been looking for a clean amp for ages, and when I actually played all the amps I read about I disliked every one of them and ended up liking the Peavey classic the most.
Sorry for the lengthy posts, hope I helped!
