HDMI cable or sound connect on tv

Good Lord above.

This may well have been written in Sanscrit.

Just what ( the 'what' in italics - cr@ppy Betfair won't let you do italics anymore) does it mean?

Optical cable is the way to go.but dont forget to take the little plastic thingys off.

shame that we can't write in italics now 

As he says Optical

Bluetooth uses a limited bandwidth and used codecs to compress
(unless you have lucky to have both devices that can use less limited codecs)

If I read this right, it's impossible to say. The HDMI is digital so lossless, so what it comes down to is probably the quality of the digital to analogue circuit, is the TV or soundbar better? Nobody knows. Suck it and see.

Optical is irrelevant, hmdi will be just as good. digital is digital.

Spot on. When I say the disparity in prices between different HDMI cables in places like Tesco or even electrical stores, I chuckle - "oooh, I'll have the gold plated ones for £20....."
HDMI is HDMI, it either is, or it ain't.

Ebay, 10 metres long, £12.99 and it works,
HDMI v1.4 PREMIUM Cable HDTV 3D 1080P
Yes Desmond,
"Gold Plated Connectors for Optimum Clarity in Signal"

Poundland sell hdmi cables.

Back to the original question if it was a good soundbar and an average TV I'd guess HDMI cable is best as the soundbars entire job is to do good sound so you'd think they'd pay closer attention to it.
