I'm a luddite when it comes to TV surround systems, I have a tendency to buy stuff, hook it up and hope it works out of the box. That all said, I am an audio nerd and have some decent hifi gear that I enjoy very much.

I recently moved and got fed up with a multitude of speakers, wires and trying to get them to work in my place so I decided to bite the bullet and get some new gear, specifically the Sony Quad system. I then realised that Focal/Naim just released the Hekla which aims to replace multiple speakers, wires etc so I bought one.

Unfortunately, it's not working as well as I'd hoped due to the unavoidable corner position so it's going back. I also didn't get any noticeable surround when playing DVDs or Netflix. The Hekla works by firing off walls and ceilings to get the surround effect but because of the poor positioning it's not working as well as it should. I did expect some compromise but also expected to at least some surround as Focal/Naim have a good reputation for quality gear.

Anyway, I thought this evening that one of the problems might be my TV and its sound output as it's nearly ten years old. It's a Sony Bravia 49XE9005 and the only output it has is PCM. This is where my knowledge stops, I have no idea if this is a good enough signal to feed the Hekla which is Dolby Atmos enabled with 15 odd speakers firing off in all directions.

Is PCM good enough or should I have a newer TV with the appropriate outputs?

Your TV looks to have an ARC HDMI connection. And the Hekla has an ARC input. I'd try that with a decent HDMI cable.

That should ensure you get a decent audio stream from TV to Hekla.

I think PCM is often stereo limited.

Saw the Hekla in a mailshot from Sevenoaks Audio. Looked interesting... Though am skeptical of this type of product with compromised TV positioning.

Aye, I've gone ARC to ARC but I wondered if the PCM output was an issue. What would you say a decent HDMI cable is?

Here is a link to the manual


https://www.sony.com/electronics/support/res/manua...

from the above . . . Page 17

ARC (Audio Return Channel) (HDMI IN 3 only)
(Two channel linear PCM: 48 kHz, 16 bits, Dolby
Digital, Dolby Digital Plus, DTS)



Given the quality of the audio gear purchased I'd also stump up for a more modern TV that passes through all the latest audio standards smile

Cheers, is Dolby Digital etc not good enough, what should I be looking for really? I'm quite happy to get a new TV but I didn't really want to spend more money if the Hekla is still massively compromised by its position in the corner.
