Yamaha Announces new 8K capable AV receivers for 2021

Yamaha has officially announced 3 new AV receivers with 8K support. The trio - belonging to the Aventage series, comprises of the RX - A4A , RX - A6A and the RX - A8A and are said to feature 8K 60fps passthrough support as well as 4K 120fps from output sources such as the PS5/XB Series X and Nvidia's 3000 series cards through HDMI 2.1

The trio are said to feature Yamaha's "Surround AI" for spatial audio as well as support for Auro 3D format. Other features include Cinema DSP , DTS-X VRR, QMS, QFT, ALLM and support for Smart assistants - Alexa and Google.

A8A - rear

The RX - A8A is set to cost (418,000 Yen which is about $3840), A6A at (275,000 Yen/ $2519) and the A4A at (132,000 Yen or $1209). These prices are directly converted from their respective JPY and thus when available in other markets, the pricing may be subject to change.

The new Yamaha Aventage series joins the growing new generation of Yamaha AV receivers, we hope that the newer AV receivers have addressed the HDMI 2.1 bug plaguing the 2020 models (Which Yamaha is yet to work on a fix) where the full 4K120 or 8K remains "disabled" due to issues with a commonly sourced microchip and has affected not only Yamaha - but also products by Denon and Marantz as well) Source - flatpanelshd, Yamahajp .

HTC One to sell as TD 101 at China Mobile

HTC decided to invest in such a brand by launching the One series of smartphones last year, although the company was not able to impose its own product names to certain carriers. Then, just a few days ago, the company launched the HTC One, which is going to be the company’s only One-branded handset this year, a make-or-break kind of project for the Taiwanese Android maker that’s still having a tough time fighting against the competition, especially Samsung. We were under the impression that HTC will further invest in its One brand and not budge to carrier demands anymore when it comes to changing the name of the product – in the U.S., AT&T, Sprint and T-Mobile are going to sell it as the HTC One. But it looks like things aren’t necessarily so, and no, it’s not Verizon that’s going to get its way selling the One as the Droid DNA Plus, as it was recently rumored.
