hi all
im getting drawn to these two big yamaha hifi amps and seriously thinking of buying one.
the as2100 seems to be going for a extra £500 over the as1100 version in various outlets,we,re looking at £1099 vs £1599.
from what i can work out the differences the dearer model has over the cheaper one are.

1/ balanced input
2/a variable headphone stage
3/bigger power supply caps
what im not sure on are...
1/is the phonostage the same on both....i need a decent phonostage !!
2/not sure if the balanced topology is also used throughout the as2100 regarding internal signal transmission which isn't on the as1100.
if anyone knows of other missed differences then please let me know,im trying to work out if i can get away with the cheaper model and save myself a lot of money....unless i find a dirt cheap s/h as2100 of course
any help as always will be much appricated.
regards
paul
