in . . . and it's a headache for the dealer because he loses as much as 20% of the value of the (now 'ex-dem') equipment every time someone arbitrarily changes their mind, or finds it doesn't match their speakers - or just gets strapped for cash in the interim. The only way we have found to work - and it's royal pain for us - is to offer a one week home loan of a run-in unit before purchase. This enables customers to try up to five competing DACs, amps, computers, cables, what-have-you at once to make a properly informed decision - before (literally) spending a penny. I can't see how any other MO could work at all.
