Krell KRC-HR or Krell- KAV 280p

I'm looking for some help.I'm just about ready to purchase a preamp and I'm stuck between the Krell KRC-HR and the Krell KAV-280pI have read all the reviews about the HR but I'm hard pressed to find reviews on the KAV 280p.I was able to find one and it seemed very good but I was wondering what actual users feel.Acording to the people at Krell they fell that the KAV-280p is the better unit.I can purchase a new KAV-280p for the same price of a used HR ($2400.00)so money is not the subject.
Please don't wait to voice your opinion I need to make a move soon.
Thank You,Tom
