To S. Andrea Sundaram,

Is the Audio Research VSi60’s power enough for Wilson Audio’s Sophia Series 3 speaker?

Thank you for your time.

The Audio Research VSi60 is rated at 50Wpc, and I have no reason to doubt that rating. Fifty watts will drive most speakers in a mid-sized room to very satisfying levels. 

The Wilson Audio Sophia Series 3 is rated at 87dB for a 1W input. Its impedance is rated at 4 ohms, but since the VSi60 has 4-ohm taps on its output transformers, you shouldn't have any trouble. . . . S. Andrea Sundaram
