Extremely satisfied with my current rig and stable. It's been unchanged for the past 4 years.
Applification
Peavey VB-2
Avatar 4x10 Neo
Instruments (there are others, but these are my mains)
Lakland 55-01
Decade'ish Frankenbass with 2 darkstars
Peavey T-40
Ibanez full-scale Artcore Semihollow with Jack Cassady pup/elec's.
Standard P with upgraded hardwared, pup, etc
Parts (allparts , Warmoth, dimarzio, badass, etc) Jazz with P neck.
I went through various solid state heads and combos before I realized that tubes were my calling. After a stint with a Traynor YBA-200, I came to the Peavey VB2. I haven't desired another amp since.
After lugging around an 8x10 for a couple years, the switch to the avatar 410 Neo leaves me with all the volume I could want in about half the weight.
After years and owning and selling dozens of different bases, my current lineup covers everything I want and more. I've settled on a stable of instruments that all meet my preferences for p-bass width necks, mostly with classic styling, mostly passive. There just isn't anything I really want. I go into guitar stores and try things and nearly always say, "Eh, I've already got a bass that can do that".
Not to say this is entirely the end. Eventually the 55-01 will get a set of Chi-Sonics, over the years, I'll probably build another bass or two just for fun, and in about 20 years I'll probably opt for a lighter rig. Still, I'd say I'm perfectly happy with what I've got.
