John_z has given more than two cents. Great advice.
To add to the above, all options will yield a sonic improvement and it is just a matter of choosing one that is in line with your priorities in getting the most substantial sonic improvement at a reasonable budget. Of course you can consider all suggestions by John_z if you have the budget as the degree of sonic differences will knock you over if done all at one go.
I have not tried option 2 when I had the Alpha 10 so can't comment on that. Nevertheless, I would still consider an alternative amp being familiar with the house sound of the Arcam from the Alpha period. The newer Arcams may have improved over the years having a different sonic character. However, if you like the current Alpha 10's sonics then it would make sense to stick with it and consider another power amp. Before that it would be wise to check the specifications of the speakers whether they are really power-hungry or not. Otherwise you can skip option two and concentrate on the source and subwoofer(if low bass is of much importance to you).
Have fun.
