This graph shows that the SR7011’s left channel, from CD input to speaker output with two channels driving 8-ohm loads, reaches 0.1% distortion at 138.7 watts and 1% distortion at 169.1 watts. Into 4 ohms, the amplifier reaches 0.1% distortion at 203.5 watts and 1% distortion at 232.2 watts.

Response from the multichannel input to the speaker output measures –0.09 dB at 10 Hz, –0.02 dB at 20 Hz, +0.04 dB at 20 kHz, and –2.78 dB at 50 kHz. THD+N from the CD input to the speaker output was less than 0.004% at 1 kHz when driving 2.83 volts into an 8-ohm load. Crosstalk at 1 kHz driving 2.83 volts into an 8-ohm load was –71.72 dB left to right and –71.55 dB right to left. The signal-to-noise ratio with an 8-ohm load from 10 Hz to 24 kHz with “A” weighting was –107.82 dBrA.

From the Dolby Digital input to the loudspeaker output, the left channel measures –0.02 dB at 20 Hz and –1.96 dB at 20 kHz. The center channel measures –0.02 dB at 20 Hz and –1.96 dB at 20 kHz, and the left surround channel measures –0.02 dB at 20 Hz and –1.94 dB at 20 kHz. From the Dolby Digital input to the line-level output, the LFE channel is +0.03 dB at 20 Hz when referenced to the level at 40 Hz and reaches the upper 3-dB down point at 106 Hz and the upper 6-dB down point at 111 Hz.—MJP

Thank you for your detailed review! I own a pair Sonus Faber Grand Piano Domus(FR&FL), Center Domus(center) and a pair of Concertino Domus(SR&SL). I was wondering your thoughts on the best receiver to power them. A sales guy told me that the Marantz SR7011 should be plenty to power my set up but I'm not too sure about that. I have been thinking maybe just get the Marantz SR6011 and use the pre-outs with a 3 channel Emotiva XPA gen 3(which is possibly overkill) for the fronts and just power the surrounds with the SR6011. My budget is around $2,500, which is maybe not enough. I've been researching the furums for a couple of days now and haven't been able to figure out the best solution to power my Sonus Faber speakers. Any help you can provide would be greatly appreciated. Thank you!

I like outlaw audio amps more than emotiva, but both are good value amps. I live in Utah but have bought a lot of marantz gear from safeandsoundhq.com, call those guys up, they will for sure take care of you and help you figure out what to do under your budget. I bet you'd be able to squeeze in both the av7703 and a good amp.
