I'm doing a Shaw / Nobellium / Ampeg PF-20 T / BBE B Max T thing at the moment. The Shaw is pretty danged impressive for thick but clear bass. I haven't been able to get there with my HX by itself. The form factor is less important for me but I definately understand where you're coming from.
When I'm in my power trio, up against a cranked EVH 5150 (pre-amp out, we're IEM) the HX is just fine by itself. Mostly the GK model with gain dialed down. In my vocal pop thing the instrumentation and arrangements are much less dense. I'm typically using a Starfire bass and Ampeg PF-20 T. I think the Shaw will really shine there.
And yeah... I've had an Oracle twice and that new form factor is like Yummm
