While the idea of stepping out on a limb may be frightening it's often beneficial as that's where the fruit is.
We have various names for stepping outside of our comfort zone: leaps of faith, thinking outside the box, broadening our horizons. In each case, they encourage us to try something new: a cable, a regenerator, a room tuning technique.
For me, one of the biggest steps out onto that shaky limb was being swayed to build audio products around a vacuum tube input stage, something I resisted for more than a quarter of a century. The fruits of that broader horizon are as sweet as candy.
What is it you are itching to try?
