I am upgrading my home theater to 7.1 using Klipsch Reference 7 speakers. I am trying to select a good match for my receiver for this speaker set-up. I have been considering the Onkyo TX-NR901 or the Harman Kardon AVR7200. Is one receiver a better match than the other? Are there other recomendation for a 7.1 A/V Receiver? Thanks.
