My Friday-morning train from upstate New York arrived in Manhattan ahead of schedulehow often does that happen?giving me the luxury of walking, rather than taking a subway or a cab, to the Park Lane Hotel, located on West 59th Street: this year's venue for the New York Audio Show. By the time I reached the Park Lane Hotel's posh-minus entrance, I felt as though I'd entered a whole different worldbut this time I wasn't sneering. Indeed, I was wondering: what would it take for all these people of means to take interest in our little world of handmade electronics and rare phono cartridges and loudspeakers that were surely meant to be enjoyed in the largest and grandest of rooms? For people who are used to the best of everything, is high-end audio really that big a leap?
