Tell me about valve equipment

[symon]

stereo 20 from leak is a no brainer - its the valve equivalent of daddy paying for a good hooker to lose yer cherry to

gonna get myself another one at some point - just need to watch that yer speakers are sensitive enough for valves - powerful valve amps that sound good are hard to find

Lots of good stuff here, which I will come back to.

How do I know if my speakers are sensitive enough? What information do I need to know?
