David...given your home market of Texas, which is booming relative to the rest of the country with the oil shale boom, my guess is disposable income is on the rise, but I still have to believe that the bulk of the audiophile buying public (forget the non-audiophile consumer who has been conditioned to buy A/V receivers at big boxes in the $500-$2K range) in your market would think $5-$10K for an integrated amplifier is the max they would go for. I know it's a gross generalization but among the audiophile community, if you are going for a 2-channel integrated amplifier, you are either starting out or taking the next level up from your first starter integrated amp (think a move up from NAD or Cambridge Audio or Musical Fidelity or such) to the next level of performance but before committing the dollars to separates, so I think $5K is probably the sweet spot and $10K is the max.
Some integrated amps to think about that achieve very good performance for the price:
Ayre AX-5 ($9,950): 125wpc into 8ohms/250wpc into 4ohms;

The
JRDG Continuum S2 which Mike is trying out looks like a killer integrated at $10Kish and is getting some positive reviews as well.
I think this gives you a good smattering of very well received integrated amps in that $5-$10K range (except for the Simaudio 700i) which is $13K. By the way, Vitus Audio's RI-100 is a killer $13K integrated amp that puts out 300wpc into 8ohms and 600wpc into 4ohms.
I hope this gives you some ideas to think about to further research. I will add one more that I personally think is a killer integrated amplifier with cool design and it's Version 2.0 is just coming out and that is the
Pathos Logos integrated amplifier from the Italian designer (110/220wpc into 8/4ohms). When it first came out, pricing in US was $4,795. I think the V2.0 version will be in the $5,500 range. You can check out the older reviews:
