Default Amplifier for passive subwoofers

Can anyone recommend an amp which is particularly good for this job? One that is safe to use (ie with DC protection built in.)

And in theory available in the UK for a second hand price around £500

With respect, that is a hard question to answer other than "about anything will do". So, a few questions first:

a) Efficiency of the sub-woofer?
b) Tube or solid-state?
c) Generally, on the spectrum between Heavy Metal and Full Classical Orchestra, where do you fall?
d) New, used, or vintage?

Keep in mind that amplification is the least complicated part of your (any) system, and about any reasonably well designed device will work fine. Variations on that theme will depend on speaker efficiency, type of music you (mostly) listen to, and whether you want tube or solid-state. Note that tube amps using output transformers have DC protection automagically.
