2 Ch % 1% THD 8 ohm/ 4 ohm:
Denon AVR-1913: 117.7 watts/151.1 watts
Yamaha RX-V473: 96.5 watts/143.2 watts
Yamaha RX-V573: 102.0 watts/126.2 watts
Yamaha 1020: 113.5 watts/170 watts
Pioneer SC-61: 150.3 watts/247.5 watts
Harman Kardon 3650: 124.6 watts/170.0 watts
Harman Kardon 1700: 108.9 watts/ 196.3 wattsHarman Kardon 3490: 140 watts/ 227 watts
Sony DN1030: 134.7 watts/ 167.7 watts
Sherwood 977: 145.1 watts/ 209.9 watts$4,000
NAD 787: 184.5 watts/ 207.1 watts
So you can get an open box HK 3490 receiver (full new HK warranty, NOT REFURBISHED) for $300 from Amazon direct (30-day return policy) that can output 140 watts into 8 ohms and 227 watts into 4 ohms.
Here is the review: http://www.audioholics.com/reviews/receivers/hk-3490
A few things to keep in mind.
1st, DOUBLING the power only increases the output by 3dB!
2nd, a single 90dB sensitive speaker means that a volume of 102dB can be generated from 2 speakers (stereo) from 4 meters away w/ 128 watts of power.
So if your max volume sitting 4 meters away is 99dB (playing stereo, 2 speakers), the power requirement is 64 watts per channel.
I don't know about you, but my MAX volume in stereo mode is only about 93dB, which requires ~ 16 watts in a 90dB/w/m speaker.
