Power Amplifiers

Power Amplifiers are probably the easiest component to define in the audio chain. They really are a one-trick-pony as their only job is to amplify the signal from the preamplifier so it can drive the speakers. In reality, things are a little more complex than they first appear.

Power amplifiers can use different circuit topologies such as single ended or balanced. XLR sockets on the back panel are one indication but fully balanced circuits from input to output are rare and expensive so be wary. Next is the Class of amplification. In solid state or transistor amplifiers the main contenders are Class A, Class A/B and Class D. Valve power amps can usually be classed as Ultra-Linear or Triode. All the different classifications have their benefits so please ask us about which will suit your requirements best.

Next is power output and this has everything to do with the speakers you use, the size of space you listen in and how loud you normally like it. Very efficient speakers, like some of the Klipsch models we carry, could be driven by a 10 watt amp, yet strangely they seem to come to life on larger amps. The broad range of speakers we sell could be defined as medium efficiency – anywhere from 86 to 90dB. Normally any amplifier from 30 watts up could be used to drive these speakers, unless, that is, you have a big room or you like to listen loud. If either of these things are true then you will probably need a minimum of 100 Watts and maybe much more.

We have a great range of power amplifiers from diminutive 40 Watt valve amps to monster 450 Watt monoblocs and everything in between. Make sure you check out our selection from Anthem, NAD, Naim, Parasound, Rotel and many more.
