Both Jim Salk and Dennis Murphy agree that SongTowers are an easy load to drive, and that almost any HT receiver will drive a pair of them without problem. Dennis has said that any amp or receiver that can deliver an honest 50 wpc at 8 ohms will get the job done.
I have heard SongTowers (my own or another pair) driven by a variety of receivers or separate amps. All of them do very well:
- Older Denon HT receiver (70 wpc at 8 ohms)
- Outlaw RR-2150 stereo receiver (100 wpc at 8 ohms, 160 wpc at 4 ohms)
- Audio by Van Alstine Insight 250 amp (125 wpc at 8 ohms)
- Audio by Van Alstine Ultimate 70 tube amp (35 wpc at 8 ohms)
- B&K EX4420 amp (200 wpc at 8 ohms, 350 wpc at 4 ohms)
SongTowers can easily handle high power, but they do not require it to sound good.
Have you already ordered STs? If so, congrats

If you haven't yet and are on the fence, I feel very confident in saying you're gonna love them.
