If you use 6 x AA NiMH rechargeable cells you can have 2A/Hr rating which
means they will outlast even the best pp9 the overall voltage will be
lower
but it shouldn't affect the audio.

Pete,

Thanks for the response. I was confused because the only PP9 specs. I could
find claimed something like 4000mAH
(http://www.entertainmentathome.co.uk...es.htm)whereas
AAs the best AAs are 2500mAH. Surely this makes a PP9 "higher capacity"?
