ULTIMO
3500 €
A statement power supply.
All JCAT power supplies are assembled by hand with the utmost care to ensure exceptional quality. Such high standards naturally restrict our production capacity and, at times, the demand for our power supplies outpaces this capacity.
ULTIMO is made to order. Current lead time is 4 weeks after placing the order.

NO COMPROMISES – THE EPITOME OF POWER AND CLARITY.
Inspired by the legacy of the OPTIMO 3 DUO, the ULTIMO is crafted for the most discerning audiophiles.
key features
- Larger Bespoke Transformer: Custom-ordered based on our design with reduced inductance and minimal stray field. Magnetically and electrically shielded, it operates entirely in the linear section of its magnetic core’s characteristic.

- Silicon Carbide Diodes: The semiconductor SiC technology, far superior to silicon diodes, features virtually zero turn-off time and negligible oscillations. This reduces noise levels significantly when compared to standard semiconductor rectifiers, a primary noise source in linear power supplies.
- Three-stage Topology: ULTIMO boasts two regulation stages with a voltage buffer in between. Voltage post the initial stage is buffered at a very low impedance to enhance the power supply’s dynamic attributes, which then proceeds to the second stage. This configuration ensures optimal working conditions for the final output stage, minimizes its thermal load, and isolates it from low-frequency disturbances emerging from the AC voltage rectification process. The ultimate sound quality is guaranteed.

- Minimal Noise Pathway: An innovative JCAT-designed PCB technique, optimizing component placement for noise filtration right at the source, ensuring the shortest return path.
- Short & Symmetrical Current Pathway: Ensures consistent energy delivery.
- High-Grade Non-Magnetic Chassis: Crafted from quality anodized aluminum, this mechanically optimized enclosure guarantees optimum sonic attributes.

- Superior Build Quality: Only the finest components. 2oz copper-thickened, gold-plated PCBs. The ULTIMO and all its components are proudly made in Poland.
- ULTIMO DC Cable: As a companion to our flagship power supply, we’ve designed the best possible DC cable. Crafted from 14AWG OCC copper, it is shielded with minimized impedance and a unique structure that reduces mechanical vibrations. With a power supply as advanced as the ULTIMO, this top-tier DC cable is essential to unleash its full potential. The ULTIMO DC can be purchased separately as an upgrade for OPTIMO 3 DUO PSU.

‘ULTIMO DOES WHAT WE WANT when we equip a device with a high-end power supply. It cleans the sound of „dirt”, widens the frequency response and energizes the presentation. It’s a power supply that doesn’t hide anything under warming, nor does it change the tonality of recordings – it’s exceptionally true to their sound. It also gives them breath and deepens the soundstage.’wojciech pacuła, chief editor, Highfidelity.pl
