I've always rolled tubes with all of the tube gear I've owned, and none of it was McIntosh. It truly can be a sickness. Looking for rare tubes, trying out different brands and styles. Hoping that next batch will have the elusive tube that brings everything together like a ray of light shining down from above...
The exception may be Shindo owners. All the tubes are hand selected for each piece, not to mention that most if not all are from stockpiles bought many years ago. There's no need to swap tubes when you have the best of the best already.
