Nothing wrong with a persistent laser focus on a hobby of interest as long as you can afford it and it does not interfere with other more important aspects of life. Live and learn. It’s either enjoyable or not. If not, then there may be a problem.
Maintaining a focus on value helps a lot Some products offer way more value than others. I tend to seek those out. It need not cost a lot for top notch sound in most people’s rooms. Addressing room acoustics first before spending another dime helps. Invest in DSP and learn how to use it properly. DSP is the great modern “equalizer” when it comes to how things sound in your room. To not do that in this day and age can be a crippling handicap.
Personally, I have no good reason to pursue more gear at this point other than the fact that I am always interested in the technology and wouldn’t want to miss out on anything new, innovative or just plain different that might add value for me.
Paying less attention to the “news” is a big benefit the value of which should not be discounted.
