Happy listening, even to those that refuse to follow the scientific process of observation and experimentation, in their own systems, with their own ears, FOR FREE (ie: 30 day return policy, from some manufacturers).
@barts, how will you know if you don’t try? There are literally thousand’s of posts here on Agon alone that describe what they hear and how to do it. You don’t need an uber expensive fuse either. Try the Acme Special Coated Audio Labs Silver Cryo Fuses at $20 a pop.
Your ears are no worse than some of our long in the tooth members here, including myself.☺ It sounds as if you’ve already talked yourself out of trying. What’s the expression? Nothing beats a failure but a try? Remember this is a hobby and it’s supposed to be fun!
