I am 28, I have been involved in the audio hobby for about 15 years.
My high-end audio dealer is my favorite retail store and that includes all types of goods. As a 17-18 year old kid I took up a lot of their time. I probably made a purchase one out of every four times I walked in the door. The rest of the time I was consulting with the owner and salespeople, listening to equipment well outside of my price range for reference, and just picking their brain.
However, as a result of their liberal policies, zero pressure attitude, and expertise, I was able to make very, very smart purchasing decisions. By the time I was 21 I probably spent close to $8k-10k on components and accessories that have lasted almost a decade. I took a long hiatus for college and law school and am getting back into it after an almost seven year break. Or I should say, seven years of being broke.
So even though most of the time I show up there I can't really afford to buy anything and I am really just investigating, the relationship they formed with me will probably be worth tens of thousands of dollars when it is time to close the book on this system.
How does a normal, middle-class person wind up with a seriously awesome high-end system? Upgrading and trading in one component at a time, strategically and thoughtfully, over decades. That means developing long term relationships with dealers that know the equipment and the auditioning process, and want to get to know you.
The best dealer will always let you into their flagship room because that is the only place where you will get the reference you need to make the right decisions about your own system, whether it is a $2,000 system or a $10,000 system or a $50,000 system, or whatever.
