How long do you or should you keep your gear.

i have repeatedly heard Magico speakers that sounded terrible. The speakers are spectacular in their ability to accurately articulate the input. The problem, especially with Boulder is incredibly accurate (like Mark Levinson) … studio monitor stuff, incredibly revealing, but without soul. Speakers and electronics that are peerless in accuracy, but lose the music. On the other end of the spectrum my system (see my ID)… Audio Research / Sonus Faber / Transperant.

So, Magico is unassailable in reproducing their input. Incredibly well engineered. 

Early in my pursuit of a high end system it was a ongoing effort. But as my system got better and my income increased listening to music became more common and upgrading became episodic. Over the last couple decades it has been upgrade about every seven years. 
 

When you own true audiophile components then it is really 7 - 10 years to get a “wow” from an new similar component.
