I used to own Virgo II and powered them with a pair of KR Audio monoblocks which were approximately 26 wpc (I think they were specd at 22wpc, but my audio technician guy measured them at about 26wpc). I never had any issues and found that the power seemed ample, and I've since owned other speakers that definitely needed more power.
The Virgos are magical and frankly have outperformend many other speakers I've owned. One of the speakers I now own is the Audio Physic Avanti III which are similar to the Virgo but with more presence and weight. I stronly recommend placing the Virgos on Sistrum 004 Stands. I can't emphasise this enough - they completely transform the speakers, and I have no relationship with the company or any other audio company.
