How useful are hifi reviews? We consider them useful for three things: (1) Surfacing new products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've ever heard (this means they probably are legitimately great). (3) Identifying a product's unique attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we discount what reviewers say because they heap praise on everything—rarely being negative for fear of souring relationships with manufacturers. Further, they seldom have more than a couple products on-hand at once, relying on their imperfect memories to compare to past products.

Manufacturer's notes
The Ianus Essentia monoblock amplifier uses TriodeFet technology but has features that make it unique in the already innovative Ianus range. In contrary to the bigger Geminae model, the Essentia is using the TriodeFet active element in a very different topology, as this is a Single Ended design. It is also performing sonically at the highest level, and even though it is the 'smaller' model still weighs in at 80 kilos per channel.
The Ianus Essentia amplifier is not only Single Ended, it is also a Single Stage! Incredibly there is no driver stage and no input stage! This extremely simple topology we feel is a breakthrough in amplifier design, and is an elusive design goal for many, including our lab. It is only possible to execute now as we are finally able to use an active element that has the needed specifications for the purpose: Extremely high linearity, high voltage gain, high current gain and very high input impedance. The Essentia, as its name suggests, consists of only one TriodeFet stage, fed directly and used as a simple Single Ended amplifier and uses the “Essence” of the Geminea technology.
