Brian Cheney of VMPS measured the output of a Zen amp and it was well below the rated output power. As such, it would only be a good candidate for those that use highly efficient speakers and / or only listen at very moderate levels. If you can find an amp that is rated for at least a "real" 8 wpc ( 300B, etc... ), you might have better luck while still being able to retain that "tube sound" that you seem to be after. Sean
