KECES Valentina 2 DC Cable

The KECES Valentina is a DC connecting cable (1.5 m, 2.1 mm barrel connector to 2.5 mm) that connects a linear power supply with a 2.5 mm output to a device with a smaller 2.1 mm input socket.

This variant solves a common practical problem: KECES power supplies output via 2.5 mm, but many DACs and streamers from other manufacturers (such as Bluesound or Pro-Ject) expect 2.1 mm. The Valentina connects both directly, without a sound-degrading adapter.

Why the Valentina DC cable?

Because an adapter between power supply and device is an extra contact point and source of error. The Valentina handles the conversion right in the cable: highly pure OFHC copper conductors in a dual-core build with nine individual strands each, solid shielding, and precisely fitted barrel connectors for a firm, wobble-free contact.

Who is the Valentina suited for – and who isn't it for?

Plain talk: this variant is exactly right when your KECES power supply outputs 2.5 mm and your device needs 2.1 mm on the input side. If both sides are 2.5 mm, get the Valentina in 2.5/2.5 mm. And, soberly speaking: a DC cable is a finishing touch, not a sonic miracle – the real gain is the clean, adapter-free direct connection in the correct connector size.

Our verdict

The elegant problem-solver when a KECES power supply (2.5 mm) and a third-party device (2.1 mm) don't fit together directly: solidly built, well shielded, no adapter needed. At HD Zürisee in Wädenswil, we check with you which connector size your device needs.

Frequently Asked Questions

What do I need 2.1 mm to 2.5 mm for?

KECES power supplies mostly output via 2.5 mm, but many third-party devices (DACs, switches) use 2.1 mm. This cable connects both sides directly – without an extra adapter.

How do I know whether my device needs 2.1 or 2.5 mm?

Measure the inner diameter of the DC socket or check your device's datasheet. Many third-party DACs and streamers (such as Bluesound or Pro-Ject) use 2.1 mm, KECES power supplies output 2.5 mm. If in doubt, we'll check it together before you order.

Why buy the KECES Valentina from HD Zürisee?

Because the connector size has to match exactly so nothing wobbles or makes poor contact. We check the right variant with you – in Wädenswil. Free shipping from CHF 190.
