Garrett Hongo has posted a review of the Zanden Audio Systems Model 3100 preamplifier ($17,250) at SoundStage! Ultra. His conclusions:
“With the 3100, the many subtle and formidable elements of listening simply disappeared as isolated, enumerable things; when apparent at all, they seemed ephemeral events — otherwise, this preamp’s sound didn’t expressly feature any one aspect of sound over the others. Instead, what I heard was something more complete: the realism, organic flow, and lively presence of the music coming together before me in my own listening room.”
