I don't have the Puccini, but did have Delius and Purcel. I prefered them through a preamp, an Aesthetix Calypso. But I have heard and spoken with people that prefer them direct (as well as other brands, ie. Wadia, Audio Aero,Emm Labs [all of which I have owned and preferred, for the most part, via a preamp] etc. . . ). As a result, I think this may be a case of synergy since I don't think the differing opinions would be as strongly biased. That being said, I would suggest making your own determination. For what it is worth, I ran mine with a Krell amp (fpb300C) and Wilson (W/P) speakers.
