HDMI isilencer

[Bretho72]

I bought a HDMI Isilencer a couple of months ago now and man I love this thing, I understand snake oil and all that stuff but I really do think that this does make an improvement depending on what it is used on. I have 3 multichannel playback choices, 1 is Apple TV, 2 is Zappiti neo media player and 3 is a PC running Roon core.
On Apple TV yes there is an improvement much more refined and less harsh sounding, on the Zappiti not so much difference still sounds a big boomy. On the PC running roon rock playing multichannel flacs and DSD this is really good, just sounds more refined. A very good investment.

Jitter jitter go away, leave HDMI this day! Shades of Agatha (Marvel-Disney). If it works for you, it works. HDMI is a very jittery interface that certainly could have been way better designed from an electrical & jitter standpoint.

My Chris Stephen's Appletv-X (modded 2021 Appletv4k) with its own hand built linear power supply with short cable hard wired into the modded Appletv4k is another example with a very clean out HDMI interface.

Yes agree, I have modded my own Apple TV with Apple TVx design.

If the difference is measurable, it may be audible. If it isn't measurable, and you're hearing a difference, that's placebo. I guarantee the recording and mixing engineers weren't worried about jitter in their chain; the mastering engineers probably weren't, either. So, why should you? As long as your cables actually meet specifications—and, unfortunately, many don't—you can rest assured that you're getting audibly transparent signal transmission. HDMI isn't such a broken interface that it needs fixing.

So even after the mods performed on your Apple TV 4K, the addition of the ISilencer provided a "much more refined and less harsh sounding" experience. I know the answer to this already, but i dont suppose you had a way to truly confirm this with any real A/B testing?

Sounds to me like the Apple mods fell a little short for ya.
