The May Essence Newsletter is live, with a mix of music, HDMI audio education, and a little vintage surround-sound history:
If you own a vintage or legacy system and still care about getting the signal path right, this one is for you.
- Seal — Purpose in native 4K: My latest Blu-ray concert review, celebrating 30 years of classic Seal albums.
- The LPCM Backbone: A plain-English look at why Dolby TrueHD, DTS-HD Master Audio, and Dolby Atmos all ultimately depend on uncompressed LPCM for D/A conversion.
- Apple TV4K + Direct Path: Why I recommend the Apple TV4K as a serious AV source when it’s connected the right way.
- Legacy AVR Rescue: How the Evolve II-4K helps older HDMI and analog-input AVRs stay relevant with modern 4K sources.
- A little personal history: How my early work with Hafler-style ambience extraction connects to what Essence still does today — helping great audio systems keep playing better content.
