Are there other people like me ? Amazed by their low cost system :)

I have a couple of cheap systems that cost around $5000 each. They sound good, but they don’t come close in sound quality to my dedicated system where my cables alone cost more than my own her systems.

IMO, the op created this post only to hear him talk. We all know you have a $500 system that betters $500k systems, just like older posts from MC claiming his $2000 speakers bettered Wilson $800k speakers. 
We don’t need to have someone trying justify their system sound quality and the OP doesn’t need to try to push garbage about how to turn a $200 amp into a giant killer by the knowledge only the OP knows. I suggest go to audio club meetings, audio dealers, audio shows to hear what you are missing.

I am indeed amazed at how good a pro analog hardware EQ properly implemented sounds in my low cost system 

Wow, lots of brow beating and chest thumping here. Here’s the deal, it doesn’t matter what is spent on a system. If you enjoy it, then it’s all good. No explanation or justification required. But don’t judge someone who might spend more (however much) as a person sold on hype and ignorance. Our systems are individual things to make us happy. That’s all.

Pick your choice of word

Went through a few posts here and the only conclusion I came to is that you are offended by whatever words others choose. This contradicts the following statement you make:

For sure an upgrade of part at low cost unbeknowst to me is possible but i must live with what i have for now but i feel no frustration at all.

If you are content with your system, you should really not care for what others think about it. I checked your current system and it does not show a specific room or audio equipment setup. I love my system as much as you like yours. You enjoy your system and let me enjoy mine. Have fun!

I agree with griislybutter knowledge and research and listening are keys… OP it’s ok to amaze for what you have, it’s hard for others to agree when we tell them we are amaze on our low cost system.congratulations.
