It is amazing how pricing varies between the UK and other parts of the world. In Australia, pricing can vary very markedly from RRP's in the UK. For example, the price difference between the A6 and A5 after converting is approximately 440GBP, which is quite similar to their respective RRP's in the UK.
However, look at something like the Monitor Audio PL300 and Mordaunt-Short Performance 6, in the UK, the PL300 retails for about 2,000GBP more than the Performance 6, whereas here, the PL300 retails for under 1,000GBP more than the Performance 6.
Anyway, I am also looking at possibly a pair of A5 or SA1 (with their dedicated loudspeaker stands) for a separate 2-channel set-up I may be setting-up. It is a small room, measuring only approximately 3.50 metres long by 2.70 metres wide. Based on this dimensions, I am guessing that the SA1 stand-mount loudspeakers are probably more appropriate. Personally, I prefer floor-standing loudspeakers, and the A5 looks reasonably good value, especially when the SA1's are factored-in with their stands, they actually cost a little more here than the A5's.
