Complexity is available to the hobbyist as deep as he or she is willing to dig. However, I also think that simplicity is available to a similar extent, too. There are plenty of integrated amplifiers that only require your streaming login to play from the various services available. I am under the impression that there are also many “wireless” speakers that only require a Blutooth or wi-fi connection to your phone.
I am glad that the hobby has plenty of steep-learning-curve rabbit holes to explore. Unfortunately, it is a common mistake for someone new to the hobby to get too obsessive about some relatively insignificant issue (power supplies, isolation/damping, cables, etc.), at the expense of core audiophile routes (speaker/listener placement, basic equipment, recording quality). I can name two hands’ worth of mistakes I have made that could have been avoided if I knew then what I learned from making those mistakes.
Overall, though, I think too much simplicity, at the expense of choices, is bad for the hobby. How is it a hobby if you don’t have options for experimentation and small improvements? I wonder: would simplicity grow the audiophile ranks? I didn’t get onto this journey because of the promise of easy access. I got into it, because I heard Klipsch LaScalas in an intelligently-assembled system.
