Audition Spendor D7 and A7 in/near Texas (Houston)

I'm looking at a new set of speakers and would love to audition the Spendor D7 and A7, however for the life of me I can't find a dealer that has them both. The two dealers I know of near Houston is GCaudio on San Antonio which only has the D7, and then Wilson Audio in Louisiana that only has the classic line. Any ideas on how I could audition both within a 6 hour drive?
