Keces Audio
P14 Ultra Low Noise
4-Zone Linear Power Supply

World’s first 4-way audio grade linear power supply

With the new Keces P14 Ultra Low Noise Linear Power Supply, Huikank Electronic Co. Ltd. once again expands its range of power supplies under the Keces Audio brand, this time with a solution that is intended first and foremost as a reliable power supply under all conceivable conditions, but also as a particularly flexible tool.

As a little brother of the mighty P28, it has no less than four zones, where the spectrum ranges from the replacement of various plug-in power supplies to a USB isolator.

The Keces Pier Series, to which the new Keces P14 belongs, is already a very broadly positioned product line offered by the Keces Audio brand. The P14 is directly below the top model of the product line, the Keces P28 Ultra Low Noise Linear Power Supply, which from a technical point of view is very similar to the latest solution, but has six zones, whereas the new Keces P14 has four.

The all-new Keces P14 Ultra Low Noise Linear Power Supply with four separate zones acts as a basis for an accurate power supply free of disturbing external influences,  and relies on a particularly high-quality toroidal transformer and a completely newly developed circuit design, which is free of any IC and is thus designed to be completely discrete.

As already mentioned, the power supply offers four completely independently designed zones, three of which serve as replacements for classic plug-in power supplies.

This leaves one more zone, zone 4, which is a variant designed as a USB port that provides 5 V and 2 A.

Not only a USB-A port, but also a USB-B port can be found on the back, both ports will provide 5 V while there’s a USB isolator between the datalines, which will offer the full signal rate of 1.5 Mbps up to 12 Mbps and supports audio signals in PCM with up to 24 bit and 96 kHz as well as DSD.

Quantum Resonance Technology It is a feature that Keces has used in other Keces Audio solutions, and which is now also found in the new Keces P14 Ultra Low Noise Linear Power Supply, namely Quantum Resonance Technology. This is supposed to ensure that a subtle field is generated that makes all electromechanical components vibrate in unison in order to improve coherence and timing.

Much more “tangible” are features such as a very solidly constructed housing made of aluminium, which comes up with a very elegant design line and rests on newly designed feet that are designeded to guarantee optimal decoupling.

Of course, it should also be emphasised that the Keces P14 features, among other things, elegant Amp meters on the front, which will probably please many a hi-fi enthusiast.

Zone 1 provides 5 V, 7 V, 9 V or 12 V at 4 A, zone 2 can provide 12 V, 15 V, 19 V or even 24 V and 6 A. Zone 3, on the other hand, is designed for a choice of 5 V or 9 V at 2 A. USB Zone 4 is designed for 5 V at 2 A.

Reviews:
KECES P14 Ultra Low Noise Linear Power Supply by Mark Pearson @ positivefeedback.com
„The song „Reflection“ showed the bass was more powerful and more fleshed out. The piano sounds more fleshed out as well in terms of power and dynamics. Roy Haynes‘ cymbals have more impact and air around them. There are also more micro dynamics that brings out more subtle shadings of tone. The overall dynamic range of the music is wider now.“
„To say I wasn’t prepared for the shocking difference between the sound of the Roon Nucleus+ with the stock SMPS and the P14 would be an understatement. There is no going back to the SMPS that comes with the Roon Nucleus+ after you hear the P14 in your system. In fact, if you own a Roon Nucleus+, you have no idea how much better it can sound from top to bottom with the P14. The amount of information that is missing without the P14 is staggering in my system.“

„Die Qualität von Keces Linearnetzteilen ist bekannt. Das neue P14 verkörpert die maximale Qualität dieses Herstellers und ist hinsichtlich seiner Ausstattung sinnvoll konzipiert. Die Qualität der Musik steigert ein P14 klar und deutlich durch Sauberkeit, Feinzeichnung und Neutralität.“
