A few additional things that have helped me greatly in my journey:
(1) Be open minded to information and experiences of others on these threads, and not dismiss things because I am unfamiliar with it. Same with reviewers, but with a grain of salt. I never would have considered room treatments, dedicated power lines, value of cables, speaker placement, vibration control, etc. on my own
(2) Find friends that are also in the hobby that are knowledgeable and will be open to lending you equipment to audition. I have been able to join a golf league that has quite a few audiophiles in it. I’ve been lucky enough to test gear from Denafrips, Musician, Holo Audio, Chord, Schitt, Buchadt, Phiharmonic BMRs, Ascend speakers, DDCs, Supra cables, Zavfino cables, Cullen cables, Audiolab, and a bunch more as a result.
(3) Be honest about your budget, and stick to it. I have a mid-fi budget, and can afford mid-fi components…..hopefully those that punch above their cost.
(4) Be happy with what you have now, even if you lust after other products. I love my Bluesound Node 130 with upgraded PSU and LPS, Denafrips DDC, upgraded cables…..but am saving up for an Aurender unit. Would love a pair of Tannoy GR series of speakers, but in the meantime adore my Buchardt S400 Mk II speakers.
