What Makes your System Special?

Tubes, and luck with pairing different components that sound great together.

My system is so so special because for hours and hours, years and years they make me tap my feet with pleasure and joy, period!

Careful auditioning and selection of gear, so system has been built to the type of sound I prefer, allowing me to listen to high quality music reproduction for hours on end.
Desire to change anything? Only to exchange tubed gear for solid state (to reduce maintenance effort, cost of new tubes, reduce warm-up time with the ability to keep the system on 24x7 so I could listen at a moment's notice) without spending loads of cash and without losing any sound quality. But I think this is not possible. So no.

Properly tuned dedicated room and tri-amping.  All ARC gear doesn't hurt either...

It gives me love.
