Room size is around 350 sqft (6m x 6m x 2.6m ceiling) apartment living room.
1) Is it not a good idea to mix in different lines of speakers?
2) Thinking of the Yamaha A3050/A3070 as the AV Receiver, is this a good choice?
3) Do I need power amps for the Ref 5s for HiFi audio?
4) I'm kind of confused with my online research of how to pair power amps with the speakers. The sites says 1.6-2.5x specified continuous power but the Ref5s says 50-400W range, does it mean I shouldn't get something larger than 400w (at the risk of blowing the speakers)? Not sure how to connect the numbers and appreciate any pointers for reading
5) For home theatre, I probably don't need the power amps right? only for HiFi stereo into the Ref5s? What's the difference between the different types of amps like stereo amps and mono blocks?
6) But if I do have the power amps connected for HiFi, it'll be in the array and maybe I should leave them there during movies?
7) with all the different speaker ratings, how do you control the power sent to each speakers? I remember my old yamaha amp can set the size of each but is it possible to fine tune the ranges for each?
Choice of speakers:
Ref 5 x2
R900 Rears x2
R400b Subs x2
ATC HTM7 x2 (ceiling mounted)
I could upgrade the center/rears to R2C & Ref1s but not sure how that compares and if it's worth it for movies.
I also have some old B&W M-1 (mini all-in-ones), can they be used as atmos speakers at the ceiling?
1) No, it's perfectly fine to mix your speakers especially the surrounds to the fronts do not need to be "matched" at all unless you are either extremely OCD or plan on doing a lot of native-multichannel music listening (SACD/DVD-A) or multichannel gaming. For normal HT, people often allocate much more money on the fronts and the subwoofer than on the surrounds (rear/sides/heights) which only do a lousy 5-10% of the audio.
2) Yamaha is known for excellent long term reliability. Some people prefer the version of Audyssey Denon receivers have. Either way, I would spend no more than 30% of your total budget on the receiver because it has a relatively minor effect on the tangible sound quality of the system...overspending on the receiver is a common newbie mistake.
3) The Ref 5's specs do not suggest a speaker that requires an external amp, since it's listed as 8 ohms impedance and 90db sensitivity. And since you live in an apartment, I can't imagine you planning to blast them at extremely loud levels.
I would strongly agree with the previous poster's advice to look elsewhere for your subwoofer(s). There is absolutely zero need to go with subs of the same brand let alone same model line as your speakers. KEF like most speaker-dominant companies makes overpriced but underperforming subs compared to subwoofer-specialists like Hsu, SVS, PSA, etc.
To be honest, if your usage is primarily home theater as opposed to critical music listening, you could achieve equal or better results going with much less expensive speakers tailored more for home theater. The KEF R series speakers that I've personally heard (haven't heard the Ref 5s, they are about a dozen stratospheres above my budget, lol) struck me as being more suited for music than HT, frankly.
