Sorry for my late response - I am just seeing this thread. I have owned the Wells Innamorata for several months now, mated to my Clearwave 72r speakers (4 ohm, 90db efficiency with Raal tweeter Accutron midrange/woofer). At first, I was not "bowled over" by the Wells amp, feeling it was good, but not overwhelmingly so. I have very much changed my mind. Perhaps the amp needs time to break-in (due to the Bybees?), but it now sounds very liquid, with a very powerful, dynamic sound. The bass response on my speakers is superior to the bass I get when using a 150 watt/channel Bladelius integrated, which is no slouch compared to many others I've heard. In addition, the midrange is fuller and more realistic sounding, while not quite as tilted in the treble. The Wells sounds very much like a Class A topology amp - lively, but rich and warm in tone. I hope this helps; unfortunately, I have no experience with the Coda range.
