Hello:
I have owned 2 different pairs of reference 4's. I matched the first pair with a PS Audio Classic 250 i was blown away
period!!! you can't go wrong with this combo,although you don't see the classic 250 for sale very often.
The second pair of 4's were driven with 2 Quad 909 amps biamped also very nice a little bright in the mid/high.
One combo i didn't like was krell ksa200s was very disappointed there.
Hope this helps
