"One big plus from buying from brick and Mortar Store is that you cam take home and audition equipment before you buy.
Its a tremendous advantage".
I have not found this to be common at all!
In fact, it's the reason I don't patronize local brick-and--mortar stores-- they expect me to lay down thousands of bucks based solely on a showroom demo using their gear in their room. Such a business model-- wherein I'm expected to accept all of the risk-- is one I absolutely refuse to engage in or support.
I've bought two components, including my recently-acquired Hegel H390, from Kevin Russell at Listen Up in Denver, a brick-and-mortar store that offers a return policy.
I bought my DAC from Alex at Alma Music in San Diego, who was willing to first ship me a demo unit.
These are the type of dealers I'm happy to patronize. Unfortunately, I've found them to be the exception, rather than the rule.
