Podcast #1147: Is QDEL The Future of Display Technology

On this week’s show we compare Mini-LED vs OLED and we put a high end listening room based on products that were exhibited at this year’s AXPONA show. We also read your email and look at the week’s news. News:   DirecTV and Dish Back Fubo in Its Spulu Antitrust Suit | Next TV  Roku Upgrades Viewing Experience with New Features | TV Tech  Hub: Smart TVs Now in Nearly 8 of 10 Homes | TV Tech  Disney Plus Looking To Integrate Always-On Linear Channels  Other:   Credit cards abused again in second Roku hack affecting 576,000 - FlatpanelsHD  NBCUniversal Launches Personalized, Hyperlocal Services via ATSC 3.0 | TV Tech  Mini-LED vs OLED We are asked from time to time to recommend a particular TV or in some cases a technology. Right now, in our opinion, the best TV technology is OLED. But is it really the best overall? Let’s take a look at OLED vs mini-LED in six important criteria.  Sharpness and Resolution: Both OLED and Mini-LED TVs typically offer 4K resolution, with some models supporting higher resolutions. Therefore, in terms of sharpness and resolution, it's a tie between OLED and Mini-LED. Black Levels: OLED TVs excel in producing true blacks by individually turning off pixels. Mini-LED displays have not completely achieved this level of per-pixel control. In this aspect, OLED emerges as the winner for its superior black levels. Brightness and Contrast: OLED TVs offer deep blacks for infinite contrast ratio, while Mini-LED TVs can achieve higher brightness levels. Mini-LED takes the lead in brightness, while OLED wins in terms of contrast ratio. Color Quality: OLED TVs typically exhibit excellent color quality, often surpassing 100% of the sRGB color gamut. Although Mini-LED TVs may not reach these levels, this is more due to other factors like color filters rather than the Mini-LED technology itself. The winner in color quality is OLED. Viewing Angles: OLED TVs generally have wider viewing angles compared to LCD TVs, including those using Mini-LED technology. While Mini-LED TVs can vary based on the type of display used, OLED usually outperforms them in terms of viewing angles. Size and Price: In terms of size, both OLED and Mini-LED TVs are available in various sizes to suit different preferences. However, traditionally, OLED TVs have been more expensive compared to Mini-LED TVs, which could be a consideration for some buyers. Price and size considerations may vary based on individual preferences and budgets.  So which one wins? It's our opinion that OLED has the absolute best picture but mini-LED is very close and unless you are looking at them side by side you won’t notice. It really comes down to cost and since you can buy some really big mini-LED TVs for a quarter of the price, we give the nod to mini-LED. AXPONA 2024 AXPONA 2024 wrapped up last week. What is AXPONA you might ask? From their website:  AXPONA is a three-day experience featuring multiple hotel floors packed with over 200 listening rooms. The Expo Hall featuring The Record Fair, The Ear Gear Experience, and seminars. Whether you’re a serious audiophile, a newcomer to high-end audio or simply a music lover, you’ll find everything you need to immerse yourself in your favorite sounds.  It's very similar to “The Show” that we have out here in CA every year. This year it will be June 7-9 in Costa Mesa so come out and let’s all go! While AXPONA exhibited products that most of us can buy, there are some that, quite frankly, are priced for people fly on their own jets. They probably don’t even listen to podcasts, so let’s make fun of them!! Kidding of course. Today, our very rich uncle who has $150,000 laying around has asked us to put a system together so he can listen to his extensive vinyl collection! Transrotor Tourbillon FMD The Tourbillon FMD is a premium turntable model with high-end features designed to deliver exceptional performance in the audio playback experience.  The Transrotor Tourbillon FMD stands out as a top-of-the-line turntable with innovative features and premium construction materials aimed at audiophiles seeking unparalleled sound quality and precision in vinyl playback. With its advanced FMD bearing technology, dual tone arm support, and included accessories, it offers a premium and comprehensive audio experience for discerning enthusiasts in the high-end turntable market. $60K with Cartridge Fern and Roby Amp No. 2 Amp No. 2 is our second collaboration with Michael Bettinger who has been designing and building amplifiers for nearly 40 years. Integrated amps make building a great high fidelity audio system easy. Our goal in this project was to produce something that will turn your living room into the best listening room possible. Fewer components, cables, and cost, but delivering world class audio into your home. $8500 (Add $350 if you want Isolation Feet)  Acora SRB Reference Loudspeaker Acora Acoustics loudspeakers are constructed using hand crafted, specially treated granite enclosures. The rigidity of granite far exceeds that of traditional particle board or wood enclosures. One of the benefits of this is as the SRB’s drivers move to push air / create sound, the enclosure isn’t absorbing this energy and dulling or smearing the sound. Another benefit of the Acora enclosure is it does not need internal bracing to “stiffen” the enclosure. This means no additional reflections inside the enclosure that will vibrate the low frequency driver and smear the sound. The SRB also utilizes world class drivers and a hand built crossover network, however the real secret to the Acora Sound is that you only hear these, not the enclosure. Sensitivity 86.5 db  Frequency Response 43Hz - 35KHz  58 lbs each $37,000 pair

Technics SU-GX70  Network Audio Amplifier Review Listening to music takes three elements, the music itself, the speakers, and the amplification. If one of these elements is not up to the task, your entire experience will be less than desired. Great speakers take high quality audio to even higher levels. The converse is also true, poor quality audio files will sound even worse.  There is a middle layer that we don’t talk about as much, and that’s the amplification. Back in the 70’s all we cared about were watts! The more, the better! As a teenager I did not appreciate that not all power is created equal. Smart amplifier design can make your music sound even better and that’s what the engineers at Technics have done with the  SU-GX70 Network Audio Amplifier (MSRP $1999.95). The GX70 is a box that has something for everyone. First and foremost it's a digital amplifier that outputs a total of 80 Watts into 8 ohms and supports a ton of physical connections including: Line level x2, phono, HDMI ARC, optical x2, coaxial, USB Type A, USB Type B. Supporting HDMI ARC allows you to connect your own speakers as a soundbar alternative.   As far as wireless connection goes, you have Wi-fi, ethernet, Bluetooth, Google Chromecast and Apple AirPlay 2. DAB (Digital Audio Broadcast) and  FM. You can also get access to Spotify, Tidal, Qobuz through the app.  Hi Res is supported via the USB port with a DAC that can decode 32-bit/384kHz PCM and DSD512 files and it can handle MQA streams from Tidal. This is one versatile integrated amp!! Setup To connect the GX70 to the network you use the Apple Home (or Google Home) app. Which seemed odd to us since there is a remote control and display screen. But once you are connected to your network you can use the Technics Audio Center App to control the system. Actually, the only reason you would need the app is if you want to send MQA streams to the amp. All the radio stations that are available through the app are available on your phone or tablet via apps source apps like iHeart Radio. You can tweak the amp to dial it in for your speakers through a calibration on the amp. But it sounded really good right out of the box.  We’ll give it an 8 out of 10 for setup, knocking off two points because you have to use Apple/Google Home to get it connected to your network. The aforementioned remote is a better way to use and interact with the amp. You pretty much just need to connect your speakers and you are good to go. Sound To test the audio we turned to the HT Guys Listener Playlist (Playlist available on  iTunes,  Amazon, and Spotify)  and listened via Airplay2, Bluetooth, and USB. All the music was played in the highest fidelity available on the platform. Both Airplay and Bluetooth lowered quality to fit within the limits of the protocol. It should be noted that the GX70 does not support AptX.  We’ll discuss Airplay and Bluetooth together and sum it up by saying the quality was good. The only thing we’ll say is that these formats work well for convenience without sacrificing too much quality. When listening to music while doing something else, this is a nice feature. But for really listening to music we used the USB connection. Once connected to Listened to Steely Dan, Deacon Blues (24 bit 192kHz) across three different speakers and found that the GX70 helped capture nuances in the music that we had never heard before. The sound was clean and precise. In Stevie Ray Vaughan’s Tin Pan Alley his voice was so smooth and raspy but in a good way! It's like the amp gave it more power and weight! But can it make your walls rattle? You would think at 80W total that this was not a possibility and depending on your speakers it's not. If you have power hungry speakers they will push the amp to its limits. However, if you have efficient  speakers, it will fill the room with sound. More than we were expecting. For that we turned to UFO Strangers in the Night Live, which is an excellent album from the 1970’s, but the recording wasn’t the best. We’ll say this, the GX70 attached to Ascend Acoustics Sierra-1s, which are not extremely efficient speakers, got loud enough to where family members asked to turn down the music! Conclusion What we liked  A plethora of input sources (both wired and wireless)  Build Quality is first rate LCD and Remote make it easy to use and setup Outstanding detailed sound quality  Needs Improvement  Two app setup Would like to see Aptx for high quality audio from mobile devices. Needs a tad more power  The GX70 offers an elevated listening experience that brings music to life with clarity, depth, and immersive soundstaging making it a top choice for those who are serious about their music.
