It's a good question, and one that's underpinned by the strong possibility that you'll spend £2k on a new DB and still prefer your old laminate. As you'll pick up from many threads in this sub-forum, the relationship between money spent on DB and DB gear and the quality of sound you get, especially if you're amplifying, is far from linear.
And if you want acoustic volume, you might have to try a lot of basses, my 4/4 was a 10 year journey, but it's a shouter and a keeper on that basis
