Well, you seem to have ruled out the only two options as far as local dealers go. The other is to find a used one, or borrow locally from a private party. Some manufacturers sell direct with a 30 day return option - Outlaw is the best known, but I think the upcoming Emotiva (do a search here) is another. Threshold sells direct now, and may allow a try it period. They make great amps. At the higher end, Coda-Continuum has a sell direct and return program also, and their amps are among the best. And there is always Bryston. Buy any used Bryston amp with its no-questions 20 year transferable warranty, and if you don't like it sell at little or no loss. Audiogon is a great place to buy/sell used audio gear on-line.
