Most of the echo walls are plastic boxes. People who can't accept plastic boxes, such as me, are honestly upgrading amplifiers for panoramic sound and eARC. The sky channel chooses the reflective speakers placed on the front speakers, regardless of the effect, at least without re-buying. The theoretical knowledge here is not repeated, only the key to AV power amplifier selection is briefly introduced, and then directly enter the screening process.
1.Brand
Compared with the echo wall, Bluetooth speakers and even HiFi speakers, the sales of AV amplifiers have been tepid in China. Harman Kardon was still catching up with new technologies 10 years ago . Pioneers were still very hot in the past few years. Only Yamaha is left , Onkyo, Tianlong, Marantz are still constantly innovating, even Sony's innovation is extremely slack. In May 2019, Sound United, a subsidiary of DIE in the United States, intends to acquire the consumer video and audio division of Onkyo. Elite and Integra brand is still independent, but Denon (Denon), Polk Audio ( Bullock voice ), Marantz (Marantz), Definitive technology (Difenniti), HEOS, Classé are one, and each use of technology And related products are not surprising.
Recalling Samsung's acquisition of Harman International in 2017, AKG, HarmanKardon, Infinity and JBL all belonged to Samsung. It can be seen that the technological progress of audio equipment is very slow, and the market cannot accommodate too many players.
Looking at the domestic market now, it seems that only Yamaha, Onkyo and Tianlong, Marantz have licensed sales, and the price control is relatively strong. It is not as easy as getting a port water 10 years ago. Today, only some sellers on "salted fish" . Perhaps because of the rise of e-commerce, the AV power amplifier market quickly gathered to the head brands. Due to the large number of product models, new and old models may be sold, I can only pick some relatively new mainstream products, not to mention too niche.
2.entry-level panoramic AV amplifier screening conditions: 7.1, eARC, Dolby Vision
Atmos and DTS: X have appeared on new AV amplifiers in 2015. These brands have some minor upgrades every year. The new AV amplifiers originally planned to be released at CES in 2020 have not been moved for the time being. Yamaha will add ALLM (Automatic Low Latency Mode), QMS (Quick Media Switching) and VRR (Variable Refresh Rate), QFT (Quick Frame Transmission, for VR) to the AV amplifier. Of course, the most important thing is HDMI2.1, at least It can guarantee 8K pass-through, which also leads me to hesitate to wait. But like eARC's basic AV amplifiers in 2017 have been upgraded, maybe these functions are only a patch for 19-year products? Not good. But if you want to buy urgently, it is better to be a 19-year product. After all, some 19-year products have already begun to support ALLM.
7.2-channel power amplifier sky channel and surround and surround back shared terminals, 2 out of 1
9.2 channel amplifier surround and sky channel independent
It is the same as the previous analysis, because the positioning of the left and right surround channels is not considered for the time being, and both the Atoms and DTS: X require the sky channel (Height), so the 7.1 channel product should be selected for the entry-level panoramic AV amplifier. The corresponding panoramic sound box layout is 5.1.2. Therefore, 5.1 power amplifier is not good, if there is space for left and right surround, you can choose 9.1 power amplifier, the choice of thinking is the same, it will not be involved here.
The 7.1 (7.2) power amplifier has 7 independent amplifiers, so it is either the traditional 7.1 layout or the 5.1.2 layout of the panoramic sound. The rear ring and surround must be abandoned, but for users without left and right surround speakers, it is just right. Like my Onkyo 6051, these two amplifiers have not been used for more than a decade. The AV amplifier's .1.2 does not mean the built-in subwoofer power amplifier, only that there are several subwoofer audio signal outputs (subwoofer pre-out).
The importance of eARC is self-evident for the power amplifier, especially in today's popular streaming media. Many AV amplifiers have supported eARC by upgrading firmware. If you choose an old model, pay attention to whether it is in the upgrade list.
