Get your home theater up to speed with the SPDIF iPurifier2

If you're a movie buff or a serious gamer, you know how important stunning sound is for the ultimate home theater experience. The SPDIF iPurifier2 offers the solution to a common problem in mainstream devices such as Apple TVs, PS5, Xbox and 8K Smart TVs: poor transmission quality of the S/PDIF signal due to jitter. With the SPDIF iPurifier2 you can get a fully restored, jitter-free signal, giving your sound greater dynamic contrast, more warmth and sharper details.

The brand new SPDIF2 is state-of-the-art with features such as the super-fast 10Mhz Global Master Timing femto clock and 100uF x 4 tantalum capacitors for better power supply ripple. The device features galvanic isolation, gold-plated EMI/RFI shielding, and iPower (5v) over USB-C for phenomenal performance.

The SPDIF iPurifier2 is Bit Perfect and works with DTS, DOLBY Digital and DoP signals. It offers full HD support up to 192KHz and can be operated with Toslink and digital cables on virtually any S/PDIF source. It can output both S/PDIF and optical signals simultaneously and also function as a coax-to-optical converter.

If you have a high-end CD player and a DAC with S/PDIF port, you should try the SPDIF iPurifier2 in your system. Its jitter-busting capabilities are quite impressive as it is galvanically isolated and has extensive jitter-avoidance technologies.

The SPDIF iPurifier2 goes through 4 comprehensive stages - isolation, regeneration, memory buffering and re-clocking - and restores the industry standard "square wave" that represents the desired signal. The result is a fully restored SPDIF signal with no jitter. With the additional Reclock® and Regenerate® features, the signal remains pure and strong, ensuring bit-perfect signal transmission, which is highly unusual for SPDIF devices.

If you're looking for the ultimate home theater experience, the SPDIF iPurifier2 is the perfect addition to your system. Enjoy movies and games like never before with stunning sound to match the picture quality.
