What specs are important when buying a 7.1 home therater system. ouput/wattage per channel etc.?

Answer 1

Hi.What is more important to you? A 7.1 Home Theater Receiver with all the latest video features crammed into a box with a Preamp/Processor section,aTuner section and seven Power Amps section all with one power supply to run it. Or is sound quality your main concern ? You will not get the best sound available if everything is crammed together in one box.The best Amplifiers for surround sound are a separate PreAmp/Processor and a separate Multi Channel Power Amplifier.

Loudspeakers are a personal choice because every one has their own taste.All loudspeakers add their own "sound" to the sound they are reproducing.That is why they all sound different.Specifications do not tell you how a speaker sounds,however there are certain specifications a good loudspeaker will have. For example :.A flat frequency response from say 40 HZ to 20k HZ plus or minus 2 db is excellent.
A Sensitivity of 85 DB/SL and higher will be satisfactory. The power rating of the speaker will depend on the size ,shape and furnishings of the room your equipment will be in. Also the Amplifier you buy will determine the safe use of your speakers.

Good quality Interconnects will make a difference.So will the speaker cable you buy.

There are FOUR basic rules to building or improving a Home Theater System.These rules are always the same,regardless of the size or price of the system.This is the key to understanding how to create a successful system from the hundreds of components available.

[1] The Equal Importance Of All Parts---The Balanced Approach.
[2] Keeping It Simple And Minimizing Change.
[3] View The System As A Whole
[4] Audio And Video Reproduction Are Damage Control Jobs.

Sound travels from the Source Component (DVD.CD.VCR.Satellite etc.) to the Pre-Amp/Processor ,to the Power Amps,and then to the Speakers.The base rule is the signal can never be improved within the chain once it has started.It can only be maintained or degraded.Audio and Video reproduction are damage control jobs.If we don't get quality information from the Source, the Preamp,Power Amps and Speakers cannot improve the signal.The Preamp and Power Amps just make a bigger copy of the signal,which the speakers reproduce.No equipment can improve the signal given to it.What is generated from the Source component will be reproduced,but not improved ,in the chain.Therefore,the goal is to change the signal as little as possible.

Answer 2

How it sounds and the price. Don't pay so much attention to specs that you overlook how something sounds and how much you spent for it. I've been seeling HT equipment for a long time and never have I picked a set up based on specs.

Ofcourse it should do what you want. If you want a multizone receiver make sure it doesn't just have an AB switch. Plan on having a plethora of HDMI equipment make sure your receiver can handle what you have know and inthe future.

The problem is that you will always want everything until you see the price tag. If price is not an option go with flagship equipent from whatever manufacturer you want.

Go visit some a/v stores and get to know something about equipment. I like Pioneer, Denon, Marantz and Yamaha. Yamaha is probably my favorite for receivers. UNLIMITED budget check out Mcintosh, or Primare. I still like yamaha.

Speakers: What do you listen to. That is question #1 Question # 2 Budget. You may want the speaker that Blow the cloths off of women when they enter the room but can you afford them. Martin Logan are the speakers. Paradign, Meridian, Vienna, Def tech. All wonderful choices but I stress again you must listen to them. Specs mean nothing here. two speakers can have the exact specs but sound completly diffeerent.
If you plan on buying without listening then good luck.
