AVR wise you'd be looking at something like:
Denon X2700, the Yamaha RX6VA or the Yamaha RXA2A. The first two are in the £650 price range and the third is around £900, but has more power per channel. Other than that they all have similar specs and will do 5.1.2.
Denon amps tend to run hot. I have a couple of USB powered fans on mine.
Input switching is simply a case of selecting the source on the remote for the AVR.
Speaker wise if you want something small, the Q Acoustics i7000 will get you the 5.1 channels for around £1000. Or the Q3000 series, which are more bookshelf size for £775.
Q Acoustics also have an in ceiling range starting at £149 per speaker.
Dali Spector 1's are another well reviewed small speaker at around £180 a pair and the same for the centre. Or a 5.1 package at around £900
Dali also do in ceiling speakers at £340 a pair.
Alternatively you could buy the speaker in pairs and the centre separately and buy a better sub from someone like BK Electronics. Their entry level subs start at around £250 and are excellent value for money.
You could also save money by looking at the second hand market.
Could I please ask a question on the first two you quote here?
Due to distance I think I'm going to need to run a cable from my pc to an avr then to the TV.
I have an RTX 3080 and an LGC1 so I would like to be able to still have 4k 120hz by the time the signal gets to the TV.
Are the two you mention capable of this.
Thanks in advance
The Denon will be fine at 4k 120hz provided it was built from May 2021 onwards.
The Yamaha may require a firmware update.
As for HDMI cable it depends on the distance between them.
Generally it's recommended that you can use a passive ultra high speed cable up to 3 meters long and still get the full 48gbs required for 4k 120. Anything over that and you'll need an active cable.
Yeah, I'm going full idiot on my cinema room (separate processor, amps, 7.2.4 speaker, buttkicker) but might pick up this short term while I save up to get matched speakers. I'll then just demote the Sony to the lounge.
I suppose there would be no way of checking when it was built though right. When I was looking the 2700h was the one i was looking at.
I think I'm ok on the cabling. I have a 3m 2.1 now i just have to move the pc nearer the tv when i want to play. As long as i can get the same 48gbs per second to the AVR which is closer than the tv then i think it should work.
Just need to figure out how to get one of those 2700h post May units.
Thanks for the help
