Zu Soul Superfly

Hi everybody, I'm looking into buying a good tube amp for these speakers. Do people have any good tube amp recomendations for a medium room for moderate listening? I'm currently looking at a couple amps, one 35 wpc and the other are 70 wpc monoblocks. Would getting monoblocks for these speakers be overkill, or do they benefit from the extra power going from 35 to 70 wpc?

Thank a lot!

After a lot of shopping around and asking for opinions, I've decided to buy myself a set of Atma-Sphere M-60s that I found a great deal on locally. They would generally be way out of my price range, but discounted they seemed like a wonderful bargain for a set of Zu Superfly speakers. Even though they are 60 wpc, I feel that OTL amps will make very nicely with the 16 ohm impedance of the Superflys.

Now I'm just worried that I will probably need to buy a good pre-amp since both Zu speakers and M-60 will both be extremely revealing. I was hoping to use the pre-amp function in my Perfectwave Dac (+bridge), but the digital volume control might not do the system justice. Any opinions?

Thanks for the feedback Wilson. I also spoke to a local dealer who told me it probably would be an issue running straight from the Perfectwave dac since it would be a little too harsh. Anyhow, I guess I gotta go looking for a good pre-amp for the setup now :) Anybody how any more suggestions about good pre-amps for atma-spheres?
