Dallas DFW speaker crossover repair gurus that you'd trust

Looking for a speaker / crossover expert in/around the Dallas Fort Worth area who can test or upgrade or fix my speakers.  I always have something I'd like an expert to look at but don't trust your normal "speaker repair shops" who are not accustomed to specialized higher end products.

People I WISH were in Dallas:  Danny Richey with GR Research and Bill Legall.

Anyone know anyone?
