What is the most overlooked consideration?


What is the most overlooked consideration when buying a piece of audio gear? We all buy gear and we all have to make choices as to what component to get, what brand, etc. What is at the top of your criteria for choosing a piece and why? Synergy? reputation of brand ?hype your heard? it’s the best compliment to my system? warranty and service? I just wanted to try a cable? I only buy brands from the UK? Etc 

So you can tell what’s at the top of your list but mostly I want you to share what you think is a much overlooked consideration and why?
 

For myself I often think customer service gets overlooked as being very important.

@freediver when I bought my Blue Circle amp (since sold and easily sold) a main criteria in choosing a new amp was just how many are seen on the used market. 
So I could not agree more. Why are certain names more frequently seen for sale than others. It is not because so many were bought. It is because so many are for sale. 
I just sold a Musical Fidelity Ñu-Vista 600. An animal not frequently seen on the used market. A very underrated product. 

I think one of the most overlooked considerations is long-term reliability. Everyone gets caught up in specs and brand reputation, but hardly anyone asks if it will still work perfectly five or ten years from now. I’ve had gear that sounded great at first but developed issues within a couple of years. It’s easy to get swept up by new features, but I’d rather have something that lasts.

 

The crossover in the loudspeaker. I think I'll start a thread on that subject.

 

The equipment’s grip on the reproduction of the emotion of the composition and performance.  +1 for @ghdprentice term - musicality and his recommendation to not focus on the usual audiophile criteria.   The prerequisite is to experience the emotion of live acoustic and amplified musical performances.  Then you can evaluate the equipment’s grip on the music compared to this benchmark.  I agree it is unrealistic to expect to bring the music hall to your listening room.  However, the equipment should, at a minimum, bring memories of the emotional experience of a  live performance, and should evoke similar emotions to the reproduction of music in your home.  Yes, it is a  personally subjective criterion.   However, if the equipment is melodious to you, you will be engulfed in the emotional experience that the recorded composition and performance evokes.
