Legendary live-sound pioneer and microphone maker Bob Heil tells fascinating stories about his early days as a theater organist in St. Louis and his work as a live-sound engineer for groups such as the Grateful Dead, the Who, ZZ Top, Joe Walsh, Peter Frampton, Jeff Beck, and many others in the 1960s and '70s. He also talks about his involvement in the early days of satellite TV and his home-theater business, which he shuttered with the advent of cheap home-theater-in-a-box systems.

One of Home Theater Geeks' most requested return guests, Gene Dolgoff, talks about his invention of digital projection and its benefits over CRT, including much greater brightness and efficiency. He also explains his more recent work on advanced 3D compression algorithms that can transmit full 1080p resolution for each eye using the standard broadcast bandwidth and discusses the problems inherent with current 3D technology, ending with a tantalizing glance at the possibility of using holography for next-gen 3D displays.

In Part 2 of my discussion with 3D maven Gene Dolgoff, he talks about how 2D is normally converted to 3D, how his company, 3-DVision, does it differently (and better!), and the limitations of all stereoscopic 3D, including lenticular glasses-free techniques. He then explains a bit of the history and technology of holography, venturing into the mind-bending realm of four spatial dimensions, and talks about his technique for creating a truly holographic, full-color, full-motion 3D display for the home and commercial cinema.

In his second appearance on the podcast, our own Michael Fremer, audiophile extraordinaire and redoubtable raconteur, waxes rhapsodic about the dichotomy of the quality of physical media versus the convenience of streaming, then takes us on a tour of his listening room and his incredible collection of vinyl records. He also opines on the audible effect of different cables and demagnetizing black vinyl records (really!), objective versus subjective (what he calls "observational") listening, and comments and questions from the chat room.

In this episode, I fly solo, answering questions from the chat room about everything from plasma versus LCD to tonally matching the front speakers to my opinion of various specific makes and models of AVRs, TV, and speakers, and many things in between. Plus, for those who watch the video, I show you around my new podcast set and point out some of the interesting items that appear behind me as I do the show each week.
