Happy New Year!

It has been a couple of months since my last post. I regret not writing sooner but I have been consumed with responsibilities at the university, studying like crazy for my oral exam and check ride (Private Pilot – Glider Certificate), and dealing with the successful outcome of my recent Kickstarter campaign. If you were not already aware, 375 backers pledged $16,271 to help bring A User Guide to Streaming, Downloads, and Personal Audio to life. I’ve been writing almost everyday and am confident that I can complete the project by the summer 2021 deadline. If you are interested in backing the project, I’m offering a 30% discount coupon (SDPA_NYS_2021) until March 1, 2021. Simply enter the code during check out.

A New Home Theater

As I suspect most reasonable people having been doing for the past 8 months, my wife and I have been spending more time than usual enjoying the latest offerings from Netflix, Hulu, and Disney+ in our home theater. The 65″ Panasonic 3D monitor I purchased for use at the studio six years ago works just fine, but I’ve been lusting after a larger, brighter, Dolby Vision capable, HDR, OLED television for a few months. But I needed a bona fide reason to spring for a top-of-the-line model. What to do?

During a recent visit, I learned that my oldest son and his wife had been shopping for a replacement for their failing 55″ flatscreen Sony TV. Perfect. I’ll give them our older—but still very functional Panasonic—television as a Christmas present (with free delivery and setup). I paid a visit to the Santa Monica Video and Audio Center in search of a new bigger, brighter smart television. I had participated in a couple of promotional events at the request of their spokesman Tom Campbell and knew the managers of the store. I checked out the latest Sony 85″ model and then the OLED TVs from LG. I remembered that the OLEDs had won the annual shootout at CE Week a few years ago in New York City. Robert Zohn sponsors the event every year and the competition is always fierce. A few years ago, I provided the 5.1 surround system during the event and showed off my high-resolution Blu-rays in between shoot out sessions.

The LG OLEDs look amazing. I do not claim to be an expert in all things video, but I was very impressed by what I saw and what I read online after to my initial visit to the Video and Audio Center. The decision came down to size, quality, and cost between the Sony 85″ or the LG OLED 77″. With the next iteration of the Waldrep home theater on the line, I took my wife—and border collie Charlie—to the store to help with the final choice. The 77″ LG OLED prevailed. The financial transaction was completed and delivery for the following Monday scheduled—although I was somewhat dismayed when the salesperson tried to get me to spring for some AudioQuest cables. I politely declined and didn’t bother to tell him the story about the D-Tronics Youtube promotional video debacle.

I managed to get the Panasonic in the back of our SUV, drive to my son’s apartment in the mid city, and unload it into his place. He was thrilled! He didn’t want the older Denon 3808ci AVR that I brought along. My son and his new wife get by with a small sound bar. However, the implementation of the older Denon wasn’t up to the task of integrating the new smart television with my B&W 801 Matrix III surround sound setup. It lacks the HDMI ARC (Audio Return Channel) so the multichannel audio from Netflix, Disney, Hulu, and Apple TV, which now originates in the LG smart television can’t be sent to the speakers I already own. I should have expected that upgrading one component—in this case the television/monitor—would require upgrading another component. Now I’m shopping for a capable AVR.

I’ve owned Meridian, Marantz, Yamaha, Onkyo, and Denon equipment through the years, I’ve found Denon to be a very reliable and capable brand. My Meridian Processor and DVD-Audio player were gifted to me by Bob Stuart, the co-owner of Meridian and now chief promoter of the idiotic MQA process. He was originally an enthusiastic supporter of my recordings and frequently lauded my efforts in his demonstrations. However, the Meridian equipment—over $35,000 worth—proved to be very unreliable and problematic. The gear remains in my studio but hasn’t been turned on in about a decade. Having overspent on the LG OLED television, I opted for a Denon AVR-750H purchased at the local Best Buy. It handles the ARC AND eARC, which means the digital audio from the television—including Dolby ATMOS encoded programming—can be send back to the receiver for distribution to my 5.1 surround speakers. The new and improved eARC allows higher bandwidths and thus more data to be sent to the receiver for processing and conversion—no more lossy, compressed audio formats.

The inclusion of Dolby Atmos and the ever-increasing catalog of available programming on Netflix, Disney+, and Apple TV were incentive enough to make me explore adding height channels to my home theater. I did a little research and opted for a couple of Monoprice ceiling speakers costing less than $100. I just couldn’t justify spending $1000 for a big brand name when the purpose of the additional audio channels is to deliver additional ambiance. Before I cut holes in my ceiling, I hung the speakers from a couple of beams in the ceiling to see if permanent installation would be warranted. With the speakers strategically hanging over my new couch, I searched for some Atmos content. I remember going to a local cineplex when Atmos first and watching Disney’s Pixar animated film Brave. The movie is available on Disney+. I sat down and hit the play button. The first thing to come up was the Disney logo with the castle, sky full of fireworks, and final particle-effect arcing above the castle. And guess what I heard from the ceiling speakers? The fireworks and final arc exploring and sizzling overhead! I went back to the beginning of the movie and urged my wife Mona to sit in the sweet spot and experience our new Atmos enhanced system. She wasn’t nearly as enthused as I had been but the speakers are still on the ceiling. Permanent installation will happen within days.

The new Waldrep home theater is hardly state-of-the-art but it is a major step up from the previous iteration. Our COVID-19 television viewing sessions are in full UHD (4K) and with Atmos immersive, surround sound. I’ll get back to regular posting now that the new year is here. I’m spending a lot of time in front of my computer and the new home theater researching and writing the new book. I added a MacMini server running Roon and Benchmark DAC to the new system—although Roon has proven to be difficult to launch. Tech support thus far has been sketchy. More news on that as I shake out the problems.


Mark Waldrep, aka Dr. AIX, has been producing and engineering music for over 40 years. He learned electronics as a teenager from his HAM radio father while learning to play the guitar. Mark received the first doctorate in music composition from UCLA in 1986 for a "binaural" electronic music composition. Other advanced degrees include an MS in computer science, an MFA/MA in music, BM in music and a BA in art. As an engineer and producer, Mark has worked on projects for the Rolling Stones, 311, Tool, KISS, Blink 182, Blues Traveler, Britney Spears, the San Francisco Symphony, The Dover Quartet, Willie Nelson, Paul Williams, The Allman Brothers, Bad Company and many more. Dr. Waldrep has been an innovator when it comes to multimedia and music. He created the first enhanced CDs in the 90s, the first DVD-Videos released in the U.S., the first web-connected DVD, the first DVD-Audio title, the first music Blu-ray disc and the first 3D Music Album. Additionally, he launched the first High Definition Music Download site in 2007 called iTrax.com. A frequency speaker at audio events, author of numerous articles, Dr. Waldrep is currently writing a book on the production and reproduction of high-end music called, "High-End Audio: A Practical Guide to Production and Playback". The book should be completed in the fall of 2013.

    Hi Mark,
    nice to hear from you again.
    Have fun with your new home cinema setup.

    One thing, however – you wrote ‘ no more lossy, compressed audio formats’.
    eARC certainly is capable of piping lossless audio from the LG back to the receiver.
    But there are none of the apps, that you mention, that use a lossless format for the soundtrack – they all use Dolby Digital + which is lossy by definition.

    Would be nice to hear from you, if you would notice a difference from the same title from a streaming service and from a (blu ray) disc using the lossless (HD) track option.
    Just for a test – and to hear your opinion on the differences.

    Happy working on the new book….keep up the good work.


    • Thanks! You’re right, of course, about the lossy encoding schemes used on Netflix, Hulu, Disney+ and the other streaming services. I don’t think I would notice a difference while watching a movie and perhaps with music. The safe bet is to stick with discs if you’re looking for video AND audio entertainment without compromise.

    Awesome Mark. The 77 incher will be my next TV but need to get cataract surgery first so I can see it in all it’s glory!

    • Good luck with the surgery. It’s a drag getting older…been under the knife too many times myself lately. But all is good.

    Glad to see the email and post. Please stay safe, So Cal looks like a danger zone. I can’t wait for the bad decisions trying to justify that they doing something. It is a mess in Arizona too, and I’m on the Maricopa Phase 1B Taskforce probably because they are having a hard time identifying all the groups prioritized.

    Bob Stuart crossed an interesting threshold in 2020. He has lost $100 million dollars operating Meridian and MQA in the high resolution era. Tidal is in financial neverland, current liabilities may exceed revenue. They were close in the their latest financial statements.

    Have a Happy New Year,


    • Yep, they’re saying 1 in three in Los Angeles county has contracted the COVID-19 virus. We stay very close to home these days and are evening avoiding visits to the grocery store. Looking forward to getting the vaccine asap. Where did you hear about the $100 million dollar figure? I knew that Meridian was down about half that much a few years ago but the hole seems just to get larger. Was planning an MQA article today.
