1000w is a good choice all other things aside for 86DB efficient speakers.
2000 is a very high damping factor. In general, that is a good thing in regards to assuring good control of driver and avoiding "flabby bass". THat may not be ideal for some speakers though, depending, and might result in a sound that is too lean. Lower damping <50 would be a valid thing to consider to address that.
I do not see input impedance specs? That might be important especially if a tube pre-amp is used.
