JVC had the consumer projector crown, however; reviews coming out of the US put the new Sony’s as having a better picture performance at a similar price.
4K Blu-ray: Paying over £500 for a player that doesn’t have universal disc play is just a rip off.
Nothing wrong with the JBL (Even though it is a little more expensive) but if you can hide it in the cupboard then also look at the Arcam. (They look cheap and nasty and you definitely wouldn’t want one on show in your rack, but the part that counts is great)
Speakers: As always choose what suits your preferences and room. (One man’s meat is another mans poison)
