London Irish put one foot in the quarter-final of the European Challenge Cup with a convincing 59-7 triumph over Dax in Pool One.
Elvis Seveali'i and replacement Warren Fury both touched down twice in an eight-try bonus point win at the Madejski Stadium.
Seveali'i set the Guinness Premiership leaders on their way in the fourth minute and added further tries from James Hudson, Delon Armitage, Topsy Ojo and Peter Hewat.
Toby Booth's men were unbeaten in their previous eight matches including the 38-0 victory in France last weekend and they made it nine following a blistering start.
The Exiles took the lead when centre Seveali'i fended off a weak challenge from Gavin Williams to crash over.
Hudson extended the lead in the 13th minute for the hosts' second converted try.
Dax held out for the remainder of the opening half but lasted just seven minutes after the interval when full-back Armitage celebrated his return from England duty with the third try.
Seveali'i claimed the bonus-point with the fourth try in the 53rd minute before Ojo and Fury added three tries in ten minutes.
Jannie Bornman grabbed a late consolation for Dax before Hewat rounded off the scoring in injury-time.
