This thread has been majorly enlightening to me, so thanks to
@EddNog and everyone else who has contributed. At 67 years old and being involved with music for most of my life, I feel like a bit of an idiot not knowing this stuff and for the question I’m about to ask. I’ve always had decent but mostly ‘budget’ sound gear - not the cheapest, but definitely not audiophile material. The closest I’ve ever come to lossless audio was eons ago with a mid-tech Technics turntable, Nakamichi amp, and some rather large no-name speakers. I recall it sounding decent, but I know there was much, much better gear out there at the time. Thinking back on it now, we’re talking 50 years ago! Anyway, technology has come a long way since then, and even my modest setup now - bluetoothing Apple Music from iPhone to Amp Ultra with Paradigm floorstanders - is already the best sounding rig I’ve ever had … by a long shot. I’m listening to 1969 King Crimson right now, and it never sounded so good.
So before I take a plunge into true lossless hi-res sound, my question is, what kind of improvement in sound should I expect to experience?
