I’m not sure what else is made in Texas, but I would select Rythmik audio over Raven. I believe their servo subs stand out more vs other subs as compared to how Raven compares to other amps. Good news is that both are great products. 

Dan D’Agostino amps/preamps are made in Cave Creek, Arizona. I stumbled on it one day and Dan was here with his wife. He gave me a tour of the entire operation. Nice guy!

NJ--VPI
NH--Basis Audio
FL-VAC

To the OP--I did visit VAC's place in Sarasota earlier this year.  It is a warehouse full of parts, old and new units, and a lot of really sharp and nice people, not at all what I expected but impressive nonetheless.  Certainly not a factory in the classic sense.  It was nice to see that Kevin Hayes has kept his operation in the community where he grew up.
