00:00:00 – Intro

Brief world news. A major update about Tom’s new house. And Rob tried connecting a webcam to his Nintendo Switch 2.

00:13:42 – Dayton OmniMic Giveaway

One of our Listeners, Jack, kindly offered to give away his Dayton OmniMic USB measurement microphone. We will randomly pick who gets it next week. So now’s your last chance to let us know if you’d like to have it. Email us: Question at AVRant dot com

00:16:24 – What We Watched

Rob watched Death of a Unicorn.

00:25:47 – Listeners of the Week

Our Listeners of the Week are our 126 Patreon Patrons, as well as Jack.

We also appreciate the notes of gratitude for keeping the podcast going from: Anonymous, Greg, Rob M, Mark, and Sasi. Thank you to everyone for continuing to listen!

In the news:

00:30:31 – News: MadVR Dynamic Subtitle Overlay

The “entry-level” MadVR Envy Core model won’t get it, but from the Core Premium model on up, all of MadVR’s external video processors will be getting DSO, which is essentially realtime rotoscoping of subtitles to allow for changing their position, size, color, and brightness, no matter what source device you’re using: https://www.youtube.com/playlist?list=PL7419lvrgfcQzMMHbbZOhxTQ8DDGvuQNO

00:39:51 – News: Microsoft Movies & TV Shuts Down

Without warning, you can no longer buy any content from the Microsoft Movies & TV online store. You can still watch things you already bought…for now: https://tinyurl.com/mt7v9c9w

Comments:

00:43:28 – Comment: Greg – BACCH-X and his 97″ OLED Deal

Greg is a fan of BACCH 3D audio processing, but he thinks any SoundBar that includes it ought to use BACCH-X: https://tinyurl.com/4j5j4jt8

He also scored an incredible deal on a 97-inch OLED.

QUESTIONS:

00:50:57 – Christian: Outdoor TV

We make our recommendations for TV models to use on a covered deck.

00:55:55 – Anonymous: Harmony One Replacement

We warn that it won’t be a user-friendly setup process, but the Sofabaton X1S or Roomie Remote App can do what he wants if you’re willing and able.

01:05:13 – Rob M: “Hard” Acoustic Insulation

We suspect it’s Owens Corning 705 rigid fiberglass he was trying to recall.

01:13:45 – Jonathan: Miniot Wheel 3 Turntable

It can stand vertically, or even be hung on a wall, and it tracks its diamond-tipped stylus using light. Is that enough to entice us to buy this $3,400 turntable?

01:21:16 – Mark: Amplifier Discussion

Our reasons for last week’s advice. Hypex vs. Purifi. And understanding modern Class-D designs.

01:44:32 – Infinite Gary: Lack of Motion Smoothing

How come his older Runco projector model never needed motion smoothing settings, but all modern projectors come with them?

01:48:31 – Dean: Panamax Over-Voltage?

How worried should he be about a single instance of an over-voltage warning from his Panamax power conditioner?

01:51:35 – Rob’s Apollon Eigentakt Amp Review

Sasi bought an Apollon Purifi Eigentakt 1ET6525SA ST Stereo Amplifier, but had it shipped to Rob so that he could check it out before Sasi receives it.
