NHK premieres 8K content at SXSW

Japanese state broadcaster NHK demoed 8K content at the recent South by Southwest (SXSW) festival in Austin, Texas.

Video was shown on a 200in screen with a 22.2-channel audio set-up. The preview was done ahead of an announcement by the broadcaster about a new 8K channel that's set to go live towards the end of the year.

How much native 8K content there'll be on the channel remains to be seen, but with a couple of 8K TVs on the horizon, it seems some are embracing the latest TV tech quicker than expected.

Marantz PM-10

Marantz's flagship amplifiers usually take the form of separate pre and power modules but the company has taken a different approach with the one-box PM-10.

It's hugely capable too, delivering a refined and powerful - an impressive £7000 package.

Chord Qutest

Chord bills its latest and most affordable powered DAC as being the world's most advanced. Does the performance bear out that claim?

In short, yes. It's a clear, precise and subtle performer, with excellent timing and rhythmic dexterity. It sets the benchmark for its price band.

Samsung Galaxy S9+

The S8 was an excellent phone so the conumdrum for Samsung was whether they'd opt for revolution or evolution.

The S9+ is more the latter, adding tweaks to a formula that boasts fantastic performance, a versatile camera and eye-catching design. The AMOLED screen is one of the best around.
