If you are thinking about being gullible regarding fuses, cables, cords, etc, no. I haven't felt as if I have been deceived on any of these items--they have all worked to improve the sound. I am skeptical of the magic dots and stickers, though. For music purchases, it's not that we're so gullible as it is willing to take chances on a better issue, etc. Comparing hobbyists to just being consumers, people are much more gullible in buying weight loss products, beauty products for skin, hair growth products, get-rich seminars, healing pendants, televangelists, etc. Audio gullibility pales next to these attractions.
