Too Many Forums asking about how to improve ones system, etc.


I have been reading so many forum posts lately that are asking for advice on improving ones system.  They ask about amps, preamps, speakers, cables, etc., but the person asking for information does not state what improvements they are looking for.  Recently one person said he did not hear a difference with a particular product but others did.  Well that seems useless to me as I don't know what the other people were hearing with a product that I am familiar with to know how to provide advice.  There are many ways to improve ones system but we need more information to narrow down the advice otherwise you will get too many suggestions from cabling to amps, preamps, etc.  You can improve a component by replacing a few resistors but each of those has a sound so I cannot recommend something if I don't know what exactly you are looking to improve.

Thoughts????

I'm sure it varies, but IMO, many people have no concrete idea of what they are listening to.  They have little or no reference to live music and are basically making decisions based on reading reviews and forums like this.  Also IMO, the only way for these people to gain knowledge of how to put a system together is either to join an audio club or utilize the services of a dealer who can walk them through what each component contributes to a system so they can hopefully find the solution that suits them.  But many are afraid to walk into a dealer because of fear of being criticized or pressure or whatever.  That's just the nature of the beast I guess.  
Totally agree with chayro, but I will add that a large part to me is to visit hi fi stores and other properly set up systems so I can hear what I think my recordings were supposed to sound like, on a really good hifi.  Live music references is important, agreed, but I don't have Carnegie Hall in my house, so every once in a while, I will take a few LP or sacd and bring them to my dealer to hear in his megabuck system )or a manufacturer I know...).  This process has actually gotten me to where I want to be as it exposed my system for what I was lacking.  
Thanks guys.  I see where you are going and offering good advice.  I am at an advantage because I have been repairing components so I can hear/test them in my system and understand what each one offers.  I also live in the NYC area so many audio clubs, dealers, and people to hear different systems.  I also build components so I get to hear what caps, resistors, different implementations of parts can do in a system.  I still find it hard to give advice and maybe I should stop unless I think the person knows what they are looking for.

Anyway, always, Happy Listening.
As you are in NY, I would be happy to have you over and help you out to the extent I can.  Send me a PM. 
Probably 90% of audiophiles buy based on reviews. Most won't admit to it, but its easy to see. Many come here to seek conformation.
