Budget? The F36s are pretty easy to drive. Any good separates or an integrated with more than 50 watts per channel should work well. Personally, I would do a Schiit Saga or Freya preamp and Schiit Vidar amp. The combo will set you back between $1000 and $1700 depending on the preamp. You could also do a Schiit Ragnarok integrated for $1500 (or fully loaded with a phono preamp and dac for $1800 for a one box solution) or Freya with mono Aegirs for $2500.
There are many other great choices, but to me Schiit is really at the peak of price v performance. Enjoy the F36s, really a great speaker.
