SPDIF to 5.1 speakers

[nicenicenicee]

Does any one have experience of any of these device?

Amazon.com: SPDIF coaxial to 5.1/2.1 Channel AC3/DTS Audio Decoder Gear Surround Sound Rush with AGPtek USB 2.0 all-in-one Card Reader: Musical Instruments

are they useful and effective?

Thanks

Yes, they work.
What are you trying to achieve? May be there are other solutions.

These type of 5.1 decoders are available locally also Digitalbay| HDMI| HD Media player| HDMI Splitter| Digtal Bay

Yes .. Have a theoretical knowledge. no Hands on experience... but I d like to tell you just that this is a decoder/converter for 5. channels alone... there is no Amplification of the input signal.

Good thing is SN ratio=120. It will be interesting to know the DAC chip inside.

Well since few days i was spending time on this useful forum, to counter the "not so good quality of sound" in my TV. And honestly i really learned a lot. Awesome community.

i was looking at the people's budget from 35K to 60K for Different AVRs + another 50K for speakers, approximately.
And though i was greedy enough to have dolby , dts, surround sound etc etc. but wondering are they so superior in terms of SQ quality.

I have a normal 5.1 channel amplifier from a local brand along with it satellite speakers are of 4 ohm and woofer is 8 ohm. And it really rocks the room when correctly configured. (it is connected via my PC currently) and four years earlier it costed me mere 3800/- only. (if i compare it with sonodyne i can only get one satellite in this cost ;-) which i think is the lowest prices quality speakers)

On further reading i discovered that most of these hi-fi systems are capable of driving 6 to 16 ohm speakers. And those which can drive 4 ohm speakers are really really fine high end AVRs. (further out of my budget)

As i spent already 71k on a TV. so wondered if i should really invest another 70-80k on AVR/Speakers.

so i am thinking to have another 5-7 k range of 5.1 simple amplifier fed by this kind of device which can decode different dolby standard and fed seperately to these 5.1 channel.

And experiment what kind of affect they give me.

if i do cost comparision ...
my cheap option going to cost me ==> 12 K [6K + 6k (5.1 amp + decoder)]
other standard option will cost me ==> 60 K [25K (Denon 1612) + 35 K (5 sonodyne genie + wooofer)]

If i see hdmi splitter (which is also primary reason for Denon thing ) is around further 5k more.

and if i am not satisfied with above experiment, then denon thing is all the time opened.

Let me know your thoughts and comments.

Regards

Apart from my above thinking process, i would like experts/ experienced Forum Members to give their view, what all will be missing from this kind of setup.

hi buddy. i also got the 5.1 system bought locally about 4 years ago and connected it to my PC via sound blaster xifi pro usb and the speaker package costs me 4,500 (target company name ) it vibrates the windows and gives a very deep bass effect but the sound clarity was not good laack of details after that i disconnect these speakers and i ll connect the creative 2.1 which sounds a lot better and the sound quality difference was like another world although it lacks bass. so decided to buy a new package and i found this forum which was very helpful and people here point you in the right direction within ur budget. so went to take demo of onkyo 3400, yamaha 196 and denon 1312xp. you don't believe the SQ of the onkyo 3400 it was hell lot of difference than any other HTiB in that price range but it lacks bass and yamaha 196 also in the same line but denon 1312xp was just better than onkyo 3400 due to it's active sub it makes a little difference in the bass. am very much satisfied with it's performance. but i recommend onkyo 3400/3500 coz 80% of the people are ok with that system output.

so go for an onkyo 3400/3500 or else yamaha 196 which costs even less but no compromise in SQ. just audition these packages and you ll definately change your mind. coz i know i bought many speakers locally in a very cheap price and thought they were very good but after hearing those HT packages i was like no words to express.

I too was using a chinese 5.1 set before upgrading to a proper HT system. I purchased the AVR first and for a few months used the speakers of the chinese HT. They are 4 ohms but I didn't face any problems. For security reasons I set the maximum volume of AVR to 60. Later I upgraded the speakers and I instantly realized what was missing in the old setup - clear vocals, more immersible surround effect, deep bass from subwoofer etc. The important change is that now I can hear even feeble sounds and vocals that was not discernible in the chinese ht.

There would be no issue & this product can be used as external sound card/decoder.It can be connected to 5.1 speaker set.The only issue can be the distance calculation & Audissy set up present in AVR(room correction).Yes some of the video playback sw can do that too,but need to check how effectively it does.

Well i can go for 25 more k for an AVR (denon 1612), but i think for speakers i would like to spread for atleast 6 to 8 months may be an year.

Do you think i can use these 4ohm thing safely? provided that i also set max vol to 55 of avr? and how do u do that ?

 

[baijuxavior]

Yes you can use the existing speakers till you upgrade. It is critical that you should not increase the volume above a safe limit. In Denon AVR there is option to limit the maximum volume. You can also use the existing subwoofer through the subwoofer pre-out of AVR.

spirovious, If i understood the Auddyssy well and its different options EQ and EQ2 technology is not that affective and it is above this when it starts contributing to a significant impact.
What is your experience...

I tested Multieq-XT of Denon 1912 (borrowed from FM) & checked in my house.When I used flat,w/o Auddyssy, Denon 1912 was just a multi ch amplifier & nothing else.When I turned it on,Day night difference.It made a room like theater.Surrounds came alive & my warm Tannoy sounded balanced.So that is the greatness about room correction.

That is not true. Audessey EQ will definitely improve the SQ of AVR and it is very apparent while playing movies. Audessey automatically adjusts the volumed level, sound delay and frequency equalization and having autosetup in avr makes setting up your avr a breeze.
