My white knuckle sessions were in the first twenty or thirty years of being an audiophile while trying to make a decision on a piece of equipment that was very expensive for my financial situation and listening as attentively trying to discern a nuance in some sound.
Over the last twenty years I have known the field and my musical intent so well that it has been easy and the resultant component has done exactly what I expected and added to the system sound exactly as I expected... so it has been just fun.
I typically have upgraded every 5 to 7 years. In between just enjoying the music. My system has now been completely stable and I am completely happy with it for the last five years. No plans on changing it.
All generalized advice is typically applicable to many people not all. I thought might a bit too weak.
