For those who need to learn discernment in such matters, I offer my latest article at Dagogo.com, "Audiophile Law: Burn In Test Redux", wherein I show that this kind of activity is a waste of time and leads to poorer system building.
System building meaning what: throwing money for costly upgrade ?
You are an unpaid sellers of new products my friend not someone able to build a system, someone who BUY ready made electronic components...
I created for 500 bucks my own system, not with upgrades but with elementary scientific facts...
The most important one being acoustical law...
Acoustician dont need a 100,000 speakers + a 100,000 amplifier to give himself a great sound.... a blind customer yes... A blind reviewer yes...
Study more, experiment more, buy less....
By the way why are you so repulsed by a 20 bucks experiments HERE that could teach ourself something?
The self appointed "scientists" are scandalized and now the sellers of costly gear are afraid...
You are never repulsed by the marketing conditioning playing in the sellings of costly electronic design?
What are your priorities?
Mine is reaching the most perfect sound at peanuts cost.... OH! i am deluded probably, too much creative to be honest....Bordeline ? Probably.... By the way i succeeded to reach a great S.Q. at NO COST.....It is then possible.... I dont pretend to have the greatest system , read me right please, but my modest system work at his optimal quality working....And when this is the case upgrading lost much of his appeal...
