Hey guys... About a year and a half ago I bought some Jensen Speakers with the plans on buying an amp... They have been sitting in the cupboard all this time... I have finally decided to buy an amp but I have no idea what I am looking for, so I am after some advice please...

I have a HTPC so I would like to run that through the amp as well as my Xbox 360, Wii, Blu-ray Player, possibly Foxtel (Pay TV) if I ever decide to get it in the future... I would like if the amp can be on my wireless network and also stream wireless any music/ audio from my iPhone .. I would also like it to be 3D compatible for when I buy a new TV in a month or so...

I live in Australia so buying here would be preferable in case of warranty purposes but if I can get a lot better and save a decent amount I will buy online/ overseas...

My budget is anywhere up to and around $1200 (delivered) but I don't need to spend this much if I can get away with spending less... I just want to get the most out of the speakers I have and also be future proof for a while and not have to upgrade within a couple years...

The speakers I have are all Jensen QX2 Series (2007-2010) except for the subwoofer and the models are below with info I managed to find in a brochure:

2x QX-35 Floorstanding Speakers
Twin 5" 2 Way
150 Watts RMS.
92 db sensitivity.

2x QX-25 Rear Surround Speakers
140 Watts RMS.
Twin 25mm Tweeters.
Single H/duty 5 driver.

1x QX-65 Centre Channel Speaker
120 Watts RMS.
Magnetically shielded.

1x X-100 Subwoofer
100 Watts RMS Powered Subwoofer

Denon 2112 or 2312 - has airplay, audyssey xt and should be in your price range (under 1200 AUS $).

See second post here for the differences between them:

http://www.avsforum.com/avs-vb/showthread.php?t=1334369

Your speakers seem pretty sensitive so you won't need a huge amount of watts to drive them to loud levels.

You guys pay a real premium down there in Australia for receivers.

Onkyo 709 would also be a good choice but I don't think it has airplay.

I have had a look at the Denon AVR-2312 and with a quick look online I should be able to get one for $800-$900...

Just a few questions I have... Sorry if they are stupid...

It says:
'105 watts per channel (8 ohms, 20 Hz - 20 kHz, THD 0.08 %), 135 watts per channel (6 ohms, 1 kHz, THD 0.7%)'
My front speakers say they are 150 Watts RMS, my rears say 140 Watts RMS, My front center says 120 Watts RMS and my sub says 100 Watts RMS...
  1. Does this mean I can only have 105 watts running through each speaker? and will that mean they are not getting the full potential from them?
  2. How do you change it to 6 ohms so I can run 135 watts? and will that be bad for the speakers/ sub rated under 135 watts?

I have also read the AV Receivers FAQ but I still don't understand by what you mean when you say this... Can you please try explain it to me? and is it a good thing or a bad thing that they are sensitive?

Thanks again for all your help and any one else that helps =)

The sensitivity of a speaker, in you case 92 db for the LR, means how loud it will get at a distance of 1 meter in front of the speaker when the speaker is receiving 1 watt of power. Every time you double the power you gain 3 db of loudness. So, in your case, 2 watts of power = 95 db, 4 watts of power = 98 db, 8 watts of power = 101 db, 16 watts = 104 db, 32 watts = 108 db, 64 watts = 111 db, 128 watts = 114 db, all these "loudnesses" at a distance of 1 meter. Now you correct for distances. For each doubling of distance, subtract 6 db. So, for example, 64 watts at 2 meters = 105 db, which is "reference" for movies and VERY loud.

Here is a link to a power calculator you can play with:

What do you guys think about the Onkyo TX-NR809 and the Denon AVR 3312?

I have found both of these on Amazon.de for $1100 for the Onkyo and $1000 for the Denon, both prices including shipping... I am guessing if I went down the road of getting a receiver from another country I will have no warranty? Is that a big deal?

Thanks

Well is no warranty is an option then I'd take a look at the vsx-53 or the much cheaper vsx-1121. Both are well within you price range.

I was curious about Denon in Australia so I did a quick google search and found this informative forum thread:

http://forums.whirlpool.net.au/archive/1268358

I had no idea that the "market" for denon, and perhaps all, electronics was so inefficient! The true "cost" of the manufacturer's warranty seems to be extremely high due to market inefficiencies.

I would not recommend buying any relatively expensive electronics without a warranty and a place to get it repaired, unless you can afford to throw it in the trash if it's a lemon or breaks.

Are there any third party warranty companies in Australia?

I have done a bit of research and I am currently comparing the Onkyo and the Denon..

The main differences between the 2:
  • Denon has 3 years warranty and Onkyo only has 1 year.
  • Onkyo models have higher output wattage.
  • Denon models have AirPlay but Onkyo models don't.
  • From what I have read the Onkyo has better video processing.
If I decided to get an Onkyo I may as well get it from overseas as they only have 1 year warranty anyway.

Will 105-110 watts @ 8 ohms per channel be enough for the speakers I have?

Is AirPlay a good feature? and is it worth making the choice just because of it?

-------------------------------------------

Here are some of my options:

Onkyo TX-NR809 - 135w @ 8 ohms - $1670 - Warranty 1 year
Onkyo TX-NR809 - 135w @ 8 ohms - $ 900 - Warranty None (not in stock for 1-4 months)

Onkyo TX-NR709 - 110w @ 8 Ohms - $717 - Warranty None

Denon AVR-3312 - 125w @ 8 ohms - $1420 - Warranty 3 year
Denon AVR-3312 - 125w @ 8 ohms - $ 937 - Warranty None

Denon AVR-2312 - 105w @ 8 ohms - $1099 - Warranty 3 year

Denon AVR-1912 - 90w @ 8 ohms - $764 - Warranty 3 year

Also, I just had a look on the back of all the speakers and it says:

Nom. Impedance 6 Ohms

What does this mean?

Just add $100 to your budget and get Denon's flagship AVR--4311ci.

I think the OP is in Australia so I am sure the 4311 is much more expensive there. Can import it for much less but if it breaks, you are on your own.

Thanks for all the advice guys...

I was 90% about to get the Onkyo 709 from amazon.de for AU$717 but I was out at Harvey Norman (A Furniture, Electronics & White Goods store) yesterday looking for something else and found a Denon AVR-2312 for AU$779 and I just couldn't pass it up...

So instead of the Onkyo 709 for AU$717 with no warranty, I picked up the equivalent Denon model for AU$62 more with 3 years warranty... BARGAIN!!!

Then I went and picked up 32m of the heavy duty cable for AU$102... Now I just need a sub cable...

Once again, thanks for everyone's help =)

Make sure to read posts in the XX12 owner thread. Very good info there, especially the first couple pages.

I am a bit disappointed... Not the results I was expecting... I have run Audyssey, setting it at 8 different seating points... It deffinitly sounds alot better after doing this...

I have turned it up a long way but keeping it under 0db like I have read to not go over... But I thought it would shake the room or you would feel it in your chest at high volumes...

Do i need better speakers and sub? or is it the receiver limiting me?

I have turned the sub volume up the way it says to do in the official xx12 thread but it doesn't really shake the room at all... and there is a vibration coming from it when it gets louder..

You are going to need more sub.

The biggest factor in improving sound and having wow factor is changing out speakers and subwoofer. From my experiences, speakers and subwoofer should be your biggest budget in your home theater system, not electronics.

Budget and room size and if its open to other rooms state that.
I would also move this part of your question to the subwoofer forum.

Just bumped into these posts, I also have the Denon 2312 and Jensen speakers And a Jensen Sub Woofer. The speakers are around 6 years old now.
The system sounds great and rattles the house inside . ( I go outside to check that I can`t hear anything much past the house boundaries so I don`t upset the neighbours ). I replaced an 2 year old low end Pioneer Amp.
The Denon is brilliant compared to the old Pioneer, just make sure you run the full setup to get best results.
