BINGO!!!
I learn that by myself for the last 2 years with listening experiments....
I smile at any costly gear review...
Electronic design is mature for the last 60 years.... It is installation of the system knowledge that is lacking for most people not the choice of their speakers or amplifier....
All can have a very good hi-fi experience if they learn how to install their system...The best there is cost money for sure....But the diminishing return laws exist....
I dont pretend my system to be the best at all, but it gives me the best it can give, yes....Better system if badly embedded will not be better anyway....
