I have Ref 3 series speakers and they are paired with a Onkyo 898 right now. I plan on using the 898 as a pre/pro for now but I want to get a amp in the meantime. There are so many different amps out there and I have about a 1000.00 in the budget for this. I have checked out audiogon and there are just so many different amps to choose from. Do I go with Adcom, Rotel, Parasound, etc. Which one would sound the best/warmest paired with the Klipsch? Thanks for your help with my journey to separates!
