Yes, Farjamed, we should not loose respect for our audiophile elders; they do have a tremendous amount of wisdom, and also experience with gear that is invaluable.
Perhaps I was a bit too harsh on the guys at the Quad/Naim dealership in saying I would never return. They were 1.5 hours away, so dismissing it was relatively easy. Very likely I would have visited again over time had they been local. Just because one has some hearing difficulty does not render their opinion or experience of no value.
It's difficult to admit hearing limitations because the entire audiophile culture is built upon hearing well - hearing "good" (left to one's own interpetation) music, hearing it on a good system, hearing it in a good environment, hearing it with good company, hearing it with good ears as well, to a degree. Advice is assumed to be given on the basis of good hearing, which it clearly cannot always be.
A point in favor of the "buncha deaf old guys," one of whom I may be some day; their experience IS very valuable and one must sift out the wheat from the chaff. They often have a huge knowledge base of technical information about what components and speakers go best with each other, what systems are better for different kinds of music (especially if one is focusing on a specific genre of music), how different media are recorded and might sound played back, etc. Turning your back on such knowledge would be a big mistake. Listen to them and take the experience. Be willing to try a recommendation but don't be surprised if you hear something different than described once in a while. It goes with the territory.
After my frustrating experience with the CL-3 cable I by no means wrote off all older audiophiles. Some of the most beautiful and insightful thoughts have come from those who have been in the game longer than I have. I simply enforced a rule that I would weigh advice given differently if I learned that hearing loss was a factor. With time you find out who hears things similar to you and who does not. I would go so far as to say that the differences between what an individual who selects a certain type of technology, say speakers, can be more opposed to one's style of listening than whether or not they have some hearing loss.
I'm not intending to give the impression that hearing acuity is the biggest factor in finding a mentor. I believe it counts, but there are many reasons to hold in esteem audio elders and consider their advice. Simply conduct your own tests and reach your own conclusions, and eventually you'll be an old half deaf guy too (virtually before you know it)!
