I’ve never been particularly sensitive to jitter in digital audio. I think there so many other things that affect the sound more.

Pros: Cost effective coaxial and optical digital source cleaner.

The goal of the SPDIF iPurifier is to clean up jitter and electrical noise in digital input so that the DAC will more accurately convert it to the music output that you listen to….It re-clocks the digital audio signal, galvanically isolates the DAP from the DAC and uses Femto clock to provide better timing of the bitstream, together with an ultra clean power source…The unit is also a lot cheaper than the W4S Remedy Reclocker…It is beautifully put together and looks and feels to be a quality designed and built product…All in all it comes nicely packaged and definitely gives the impression of being a quality product…Does it make a difference? The answer is yes and in a good way…there was a noticeable improvement. Everything was brought into a sharper focus, the bass became deeper, the cymbals crispier and there was a general greater level of silk smoothness to the music. It had better shape and definition and a bigger soundstage which in turn meant better separation…Mariusz Duda’s whispered intro literally seemed to jump out into the room at me and all the other instruments were more clearly defined….At £145, it’s the most competitive coaxial or optical ‘data cleaner’ in the market….the SPDIF iPurifier noticeably delivers. For me it’s a keeper.
