Well as others have said and my self ONKYO is a decent brand, other to keep a eye open for are Yamaha, SONY, Denon all produce a clean sound.

Then it's about options offered by brand and if your willing to buy second hand. Then how important having blutooth \\HDMI are to you.

Huh ?,what this for a basketball court :P.
<-80ft-> or so by 100ft
 
You can get some near \ top models with 300$, well i can here if you don't need the blutooth and HDMI for sure. I don't know the pricing were you are, you know some of the models to look for and it's about find and research :).

Like if i had the money my self i be bidding on this Rotel 1056, well if i did not require HDMI that is :P. But you need one that's usable in your country so you can just plug it in.

That's my point time to search for those brands your self, in the US we have on up for bids starting at $150 and sell around $250-$300$, how much ones available were you are i have no idea.

As you don't need surround sound and all that and not to bothered about HDMI why not just get a Amplifier, options get even bigger then.
 
Mr asrock can i ask...

what if i get a system like this...

throw the speakers that is has or use them somewhere else and use that...

im jumping into hifi systems now

Where are you located? I was looking at Craigslist here in NH (US), and the Realistic STA-75 / 76 / 78 can be had for under $100. Really, really nice receiver for the coin.

:( You ignored my next two sentences.

I said, "That is, they should not introduce any enhancements on their own. They should just amplify what is inputted to them.". That can only happen if they have a flat, undistorted output. Now where the big differences come in is with the electromechanical part of the equation - the speakers, and environment (room) they are played in. But again, the electronics should be flat and only altered (with a frequency equalizer) to compensate for speaker deficiencies and room acoustics.

And FTR, while I own and like Onkyo. I am no fanboy for them. As I noted, I will probably look first at Denon when I buy again. And my very first real high end stereo system consisted of a dual monoblock Marantz power amp powered by a Dynaco PAT-4a preamp which I built! :D And they were used to drive a beautiful (sound wise) set of Acoustic Research AR-3a speaker systems - which I still have and hopefully will restore this year.

I have also owned an stereo Harman Kardon receiver back in the day which I really liked. My first 5.1 system was a Yamaha but it did not support HDMI. My current Onkyo does support HDMI.

One thing I really like about my Onkyo is the speaker calibration feature, Audyssey EQ. The receiver comes with a calibrated microphone you place where your head will be when listening. Start the process and the program calibrates the frequency response and output levels for each of the 6 or 8 (5.1 or 7.1) connected speakers. I have a nice SPL (sound pressure meter) I used for other sound system setups and I was surprised how accurate the Onkyo calibration was. It very effectively compensated for my living room which has heavy curtains on one side and opens into the dining room on the other. And the right rear is a solid wall while the left rear opens to a hallway. It really balanced the sound with the press of one button on the remote. Nice. I assume some of the better offerings from other makers offer a similar feature - but I will sure ensure the next receiver I buy does too.

For sure, Athens, as a big metropolitan city, will have high-end audio stores that sell better quality home entertainment electronics with trained people who can really tell you what's available.
 
Ehh Mr bill since you are here can you help me with one more thing i was talking about ohms
in my case my speakers say 4-8
so if the reciever says
4-16 ohms
8-16 ohms

means my speakers wont be good for that input of the reciever
or just the reciever will feed them more (sound-power) and damage them?

or in general what impact ohms have at my speakers or my listening

thank you >:I

Yeah, see that makes no sense either - at least for your speakers. While speakers don't present a constant load on amps, they typically are rated with just one impedance value, normally 8Ω or 4Ω. Not 4 - 16Ω.

It is really when using multiple speakers on the same amplifier channel that you need to worry about the impedance - at least with normal speakers designed for such use. This is because the basic formula when you put two equal loads in parallel is the total impedance is cut in half.

So if you put two 8Ω speakers in parallel, the amplifier will see a 4Ω load. Now this is where Ohm's law comes in. Ohms law says I = E/R. That is, current equals voltage divided by resistance.

So, assuming voltage remains the same, if you drop the resistance, current goes up. And when current goes up in a circuit, so too does heat! See the last line in my signature.

So the bigger problem when placing speakers in parallel is not damaging your speakers, it is burning up your amp.

Clear as mud, huh?

If you only put one speaker on each speaker output, you will be okay.

If you have some time, look up "Impedance Matching" ...the internal resistance of the amplifier should match the internal resistance of the speakers. It mainly affects the efficiency at which the power from the amplifier is converted to sound in the speaker. I do believe that it may affect sound quality to some degree, but not much.

Most amplifiers will be fine with 4-8 ohms. 8-16 ohms is rare.

Edit: https://en.wikipedia.org/wiki/Impedance_matching
 
So to sum it up..

Thank you all of you for taking some of your time to help my lazy-busy booty out

every single replay had its own help i hope some day i will be able to help your the same way...

I found more or less for what im going for so you helped me a lot

Thank you

Yeah sorry about that :).

Yeah Audyssey is pretty good but a few have it now or some version of the same thing using a mic including Yamaha.

Would not touch them even with a pole, suggest you not to if your thinking of getting in to HiFi. And the speakers to it will be crap. But then again i knew some one who used to like maximum treble with very high mid-range.

If you really thinking of getting some thing like that you should go some shops that sell them. I can only speak what i think of them but i could tell you to that my mother would be happy with it, depends what your expecting from it.

But personally hell no, they sound no were near as good but that's preference.

As you only require a 2 speaker system a normal amplifier some secondhand speakers you should be able to get for $300.

Whats the ebay link, like in the US it's .com and the UK it's .co.uk.

If the amp is designed to operate at 4Ω, it should not affect quality. In fact, because current will increase, there will actually be more wattage available which may actually help quality, at least in the low end. But that depends on the efficiency of the speakers more than anything else.
 
People tomorrow Ill make a list with the receivers that i have in mind to get so ill need you for 1 last time untill then good night!

I don't think it's that simple. Internal resistance matching (Impedance matching) concept itself is pretty simple, but there are other side effects when they are not matched, such as signal reflection. One side effect is distortion.

https://en.wikipedia.org/wiki/Signal_reflection
 
You are talking apples and oranges. I am talking about 4Ω speakers and amplifiers designed to power 4Ω speakers. You are talking about "cheap" or damaged speaker cables. Note your reference makes not one mention of speakers or speaker impedance! But it clearly states signal reflection "happens because imperfections in the cable cause impedance mismatches and non-linear changes in the cable characteristics."

Yes, quality cables and quality connections (and cable length) will change the characteristics of the load seen by the amplifiers, so for sure, "investing" is quality speaker cables of the proper gauge is important. But the OP's question was about his speakers and how they will work with his amp. Not wires.

I own a Rotel RDV 1092 (DVD/CD player) and though it cost me a lot of money it was worth every penny. I have always been tempted to buy a matching Rotel amp and preamp but I have so much audio equipment I really don't know what I'd do with it.
 
I agree about second hand deals. There are some very good deals for just sound output equipment especially on the eBay.{ ie receiver's with out HDMI]
I picked up my VSX39 TX a [$2500 Top of Line new] a few years ago for $425. In fact my remote for it runs over $200 usually $300+. Just this week seen some less than 1/2 that. In fact 1 is $165 but pick up only about 320mi from me.
I'm very tempted to get it since we will be going there to see our daughter.
So if there is some chance that eBay where you are has some it my well be worth it.
I was astonished with the quality of this unit. It will play maxed out[+12] with all 4 Pioneer CS9900 and as well with my 4 Polk 75t 2 years old now.
Best of all is with my studio monitor set of Infinity RSe's they are 4ohm speakers, and I don't try to "blast" them to those extreme sound levels, they are more for critical type listening and do they ever shine ! My previous[Mid level] older VX4800 and a Marantz just didn't really cut it. Both Pioneer's are close in output, but it's a whole different game when moving towards Loud volume's. That's where quality older units show a difference. None have changed the tonal sound but the 39TX sound is way more defined.
To test the output of the unit I did run both of the big 8ohm speakers in parallel[4ohm], and sure enough it will trip at high volumes, but just running on both sets on A,B takes care of it. The sound level was pretty much the same, just used up the output rating of the unit at a lower setting[+8]. Again the sound level was very loud, almost too much, but not like when getting into High end like say Crown, Sunfire Studer-Revox Rotel ect. those super priced units. Again this older unit is capable of very high sound levels!

Very true as I experimented :toast:

So tldr: older stuff can be great cost savings if you just want the basic functions. With plenty of digital inputs I didn't care a bit about using on screen or video switching. Just label what ever input I need to use for sound and bingo.
Also just like they're saying, about 4 and 8 ohm loads, good unit's will be able to cope with the load and you'll never notice and can get a great start into Hi-fi sound.

Now if you just want loud sound, you could get a pretty cheap [Sony DTS550 is what's in almost all Wal-Mart stores $198] receiver that may give you enough of what you'd want. They make these new models "look good on paper" so it's almost a crap shoot with what you really end up with on entry level units.
