I am supposedly a failed audiophile as well in that I now have an objectivist view. I am not surprised when I hear people cannot hear differences on kit where measurements find there are no audible differences. Those who can hear differences with such kit have more explaining to do.
I also think that very little in the hifi chain makes a night and day difference and such descrptives are inaccurate due to their exaggeration. FM radio on a mobile phone with stock IEMs against lossless files to a decent DAC and amp to some lovely AKGs is night and day. Two decent DACs or amps with flat frequency responses are not night and day, they are subtle (if at all).
IME (one that is shared by many) price and performance are not as related as many would like it to be.
So I love my music as it is very well reproduced on a not very expensive set up where I have concentrated on what matters. So I am not really a failed audiophile at all and neither is the OP nor others who think they may be. We just have a more objectivist appraoch to hifi.
