It has a much higher S/N ratio than the 1000, because it has a better DSP.
All the XLS use the same DSP
1000 s/n 97db and the others are rated 103db
But even with s/n of 97db the amp should be hiss free
I know my 1000 is noise free.
Maybe Michael's speakers are very high efficiency ?
He may need to add a 10-20 ohm 10 watt resistor inline to just the tweeters
Than reEQ the high end.
I have used this trick with great results, its very cost effective.
