I know this may be a different take on it but I have to agree with the amp opening up more with different cabs
I have been using an Aguilar AG500 since 2009 with all manner of DB series cabinets and even though they could get pretty darn loud .... I was just never satisfied with the overall tone. I am talking DB112, DB212, DB410 and DB210. Something was just missing to me so ........... I picked up a GS112 and boom ... the amp opened right up.
I have since picked up a 2nd GS112 with a net result of having to drop my overall volume by at least 1 to 2 notches which is mind boggling to me how the cabs could have made that much of a difference.
The wild thing was I sat a DB112 next to a GS112. If I had to choose 1 box in a controlled situation it would be the DB112 but on a live stage where I need projection, punch and clarity along with enough volume and headroom and bottom the GS112 x2 in my case is a huge leap forward.
I know others may disagree but what I am saying has been my experience. To make the situation a bit more clearer my comments are based on using a passive USA Bob Glaub with Lindy Fralin P/J's and a pedalboard first going into a t.c. Electronics tuner, buffer, an Aguilar Tone Hammer preamp pedal followed by an Aguilar Octamizer, Filter Twin, MXR Bass Chorus Deluxe, MXR Phase 90, MXR Overdrive and then to the amp. Even the effects are more pronounced.
I intend on eventually picking up a TH350 soon so maybe I can report on the difference however I do need to say that the cabs mentioned above at one time or another were used with a TH500 as well as my AG500.
I know this may be apples and oranges but this is what I have experienced recently so maybe just even borrowing a cab from a friend mat be the thing to do if possible to see how you like it.
Best of luck on your search too .... it can be a drag but when you find something you're happy with it makes it all worth the search
