The Orange stuff is great, but the EQ section is not very versatile. I found that it sounded excellent flat.....which is helpful, because the sound didn't change a great deal with preamp tweaking.
I had the Genz Streamliner 900 for a bit, really didn't like it, couldn't get a tone that was pleasing to my ears in a band mix.
Aguilar is a fairly safe shout, lots of love, although I've never gigged one.
Yeah get over to Bass Gear to try a bunch of stuff in their amp room, great guys and an awesome shop!
I love my Markbass stuff, so not much more I can say haha
