Audiophile OCXO clock included


Audiophile USB card V6 PPA studio Paul Pang - OCXO clock module

OCXO stands for “oven controlled crystal oscillator”.

An OCXO will always yield better results than a TCXO. And of cource a much better result than the standard clock inside a computer.

Because the oven keeps the temperature of the crystal much more stable, the clock frequency also remains much more stable & precise.

This gives an optimal timing of the signal.

You can send a much better signal to your external DAC.

No harshness

No “digital” sound

Much more tranquility

More resolution

More dynamics

More microdetails

More natural

More “analog” sounding

This OCXO-clock is currently the best clock worldwide available for high-end computer audio purposes.

2-in-1 audiophile USB solution

The V6 card are actually 2 separate cards that you can both use with the included OCXO clock. This can be interesting if you need a jitter free monitoring and recording solution, or when you want to hook up an external HDD and want to benefit from the OCXO clock as well. If you are a bit handy, you could even install this clock on the LAN chip of your motherboard, to upgrade the sound of online streaming services.


User feedback


Hi Paul, Your V3 card sounds amazing right out of the box, and powered by a regular power supply. Analogue sound, and hearing details in music that I never heard before. I run a top notch asynchronous DAC (Phasure NOS) and didnt expect much of an improvement, but I was proven very wrong. Keep up the good work and my very best to you. – Gebruiker Lineke Heus via blog Paul Pang

I bought the V3 USB card and it sounds amazing! I had an SoTM USB card, both powered by linear power supply and I found that the PPA V3 sounds much smoother and more analogue so I sell the SoTM with no regret. – Tom Fazakas via blog Paul Pang


Power supply: internal option

Paul Pang USB Card V3 power supply

Normally PCIe cards are powered via the PCIe lane of the mothermoard.

This is never the best solution for high-end audio reproduction.

The power of the motherboard is contaminated and will result in a higher noise floor.

Therefore the Paul Pang audiophile USB card V6 can be powered via a 4-pin Molex (5V / 2A min.).

This results in clean power. Music will have more tranquility, clarity and a blacker background.

Power supply: external power supply option


Audiophile USB card V6 PPA Studio Paul Pang - with DC input for external power supply

For best result you should power the card externally.

You have the choice between a 2.1 mm DC input jack or 2.5 mm DC input jack.

With this option you can use an external lineair power supply like the HDPLEX 200W LPSU. This will give you a much better result than the internal power supply of a PicoPSU.

The Paul Pang audiophile USB card V3 needs 5V / 2 amp (min.) current.

Please pay attention: a higher voltage than 5V could damage the card and will not be covered by warranty.
