Pete, we exchanged a couple emails regarding the Cyber 800s and well, I also put in a request with Vinh at Norvinz who then forwarded to Joe at Utlra Violet Audio, the US distributor for Consonance and he feels that they would work fine...
here's what he had to say below:

Vinh,
Hello. Thank you for your e-mail.
Yes, you are right, the sensitivity is not as crucial as people often believe. I think the impedance/phase angle plays a huge role. But, I personally feel the crossover topology makes the biggest impact as to whether or not the amplifier will mate well with it or not.
Based on checking their website, I see Dennis Murphy designed the crossover. Though the specs don't really look so great, this should not be an unduly difficult speaker to drive, and if the person is looking for a tube amp to drive them, the Cyber 800 should do as good a job as any amplifier in the category. Yes, he'll be able to produce 95 dB with the combination.
Thank you,
Joe
