Any good Bass Amp stores in Texas, or anywhere?

I'm looking for a store, preferably in Texas, that has a lot of big bass amp gear in the store, so I can test out amps in person. I'm looking for big cabinets, full-size stacks, not small or medium combo portable units.

Guitar Center sometimes has a few big Ampegs, 4x10, 6x10 and some SVT heads, I just wish I could try more. They rarely have more than a couple heads in stock so I can't compare enough.

Any suggestions?

Willing to go almost anywhere in the States if I have to but I'd prefer if I could find a store here in TX.

Used to go to Bass Emporium in Austin but they closed down.

Open to all suggestions, Thanks!
