The Initio 3 is the JCAT Optimo 3’s younger brother. And there is a sonic resemblance which I’ll get into. Both supplies are in the upper range of the price per rail at $885.

The Sound

The Initio 3’s signature is fair simply to describe. It’s a heavy molded sound that is intimate and solid. It amplifies certain textural cues but smooths over some of the subtleties. It has a really good low-end response, so percussive instruments sound very tangible and full-formed.

Similar to its bigger brother, the Initio carries a similarly darker tone. I definitely prefer this type of sound over an analytical or neutral one. Keep in mind, this tone is ever-present in every recording and you’ll notice it over longer listening sessions. You have to really enjoy a darker tone.

Although not particularly spacious sounding, the soundstage does feel pretty wide. But not very deep. It has a good balance of density and texture. But is a little less expressive or tangible when it comes to powerful transients. It won’t present notes with lightning speed. The Initio 3 just contextualizes the music in a more physically corporeal manner.


Overall, not a lot of spatial clarity. You won’t hear the inner details or feel that it’s a speedy power supply. The Initio 3 effectively puts a dark coating over everything and makes it enjoyable to listen to.

The highs are a little choked and the tonal balance is skewed towards the lower midrange. Textural information is sometimes indistinguishable between different bodies. The soundstage is also more intimate, especially behind the speakers.

Who Should Buy the JCAT Initio 3 Linear Power Supply?

First, you’re going to have to completely be enthralled by a thick-coated dark sound. Because you’ll hear a lot of it. Also, your preference will have to be with a more liquid and mellow signature. If you want the impression of having denser bodies in front of you, but can’t step up to the JCAT Optimo 3, the Initio 3 may be a great fit.
