This highly advanced audiophile HDMI audio extractor features custom DSD to PCM conversion algorithms and an advanced jitter reduction system. The result is a reference-quality digital audio signal suitable for the most demanding stereo and multi-channel digital playback applications.
HDMI is great for video, but can it be made great for audio? HDMI is the main method of transporting AV signals in the consumer environment. It works great with high-resolution audio and video, but it never found its way into the hi-fi world.
Apart from some non-technical reasons, one of the biggest problems associated with HDMI audio is the quality of the clock recovered from the HDMI stream and the electrical noise associated with it. Despite many improvements in the latest HDMI receivers, the recovered clock always suffers from high levels of phase noise. Although this is usually not a problem with consumer audio – home theaters, soundbars, etc. – the imperfections of HDMI audio are immediately noticeable when listening critically. Moreover, HDMI audio is known to be sensitive to various forms of electromagnetic interference, cabling quality, ground loops and is generally considered inferior in the hi-fi world compared to specific digital audio transport methods such as SPDIF, AES/EBU.
There is usually nothing wrong with the audio data itself, provided the receiver can use any of the digital formats and sampling rates available on the source side. The main issue is how the audio data is packaged and merged with the video data into a high-frequency digital signal and finally recovered at the HDMI receiver (sink) side. There are many inexpensive HDMI audio extractors on the market, and some of them are capable of outputting digital audio via S/PDIF up to a sampling rate of 192kHz. But they don’t even come close to a good digital transport in terms of audio quality.
What makes the Vanity different?
PRO
from all other HDMI audio extractors? It basically addresses all the imperfections of HDMI audio one by one, with a lot of extra features that the others don’t have. The Vanity
PRO
for example, galvanically isolates the HDMI section from the sensitive audio and clock circuits to eliminate all noise and interference associated with video transmission and HDMI signaling. Both isolated sections have their own power connections.

This fully linear power supply, built around Audiopraise discreetly designed regulators and packaged in a design-matched enclosure, has the ultimate goal of providing the cleanest possible power for the Vanity
PRO
. Although switching power supplies are small, compact and relatively powerful, they still produce a fair amount of switching noise, which can contaminate not only the equipment being fed, but also the mains in the other direction or both. This is where a linear power supply can make a huge difference in perceived audio quality.
