OK I see, any chance of hearing the 2 speakers with your amp? 1,000euros seems a fair price, if the 803s sound better than the 801s it maybe the way to go. I believe you are quoting the W limits for those speakers that does not follow that they will be more demanding, if you can find the sensitivity figs for each speaker that would help, these are normally quoted as dbs, something like 87dbs w per metre @ 8 Ohms. The higher the db figure the less power you need for a set volume.
