Question about touch responsive amplifier design

[jammybstard]

As I read more about valves and amp design I keep coming across references to touch responsive valves and amps but I haven't found a decent explanation of what technically makes an amp more or less responsive.
I seem to find with my single ended 5w kit amp (Ampmaker SE-5A) that if I crank the gain but keep the master down at bedroom levels that the amp sounds great but is very unresponsive. where as clean its very responsive. At least thats my perception.
I'm reading the Megantz tube design book at the moment which is answering alot of questions but I'd like to know what makes an amp responsive.?
