Richard,

My opinion is that you don't have to change it if your 1709 support Multichannel LPCM audio via HDMI and you want to save some money. When you get bluray player in future, just make sure you get a bluray player that can decode the HD audio format on the player itself and sent the decoded signal to the 1709 via HDMI in Multichannel LPCM format (e.g. PS3). You still can enjoy full HD video and audio this way.

If you die die must get HD decoding on the AVR itself or want more features (e.g. more HDMI inputs, more power, etc, etc.), then you have to upgrade but be prepared to pay much much more $$$.

Hope this help.

I tot PS3 can;t do it for DTS-MA? only TrueHD mah?

Richard,

Upon checking the 1709 spec in the Denon manual, the 1709 does not seem to support Multichannel LPCM. Only 1909 model and upwards support Mulichannel LPCM audio input. Guess you have to upgrade after all if you really want to future proof with HD playback. Good luck.

ar188, i thought blu-ray playback support for DTS-HD Master Audio and DTS-HD High Resolution Audio is available on the PS3 since firmware 2.36.

Yup, it's been very long time already. PS3 can decode whatever codec that exists in on BD/DVD now, lossless or otherwise.

Wow!!!
Ur reply like an advise from parents to a child.
Feels warm and really go into my heart when reading it.
Yeah, it is not future proof and it is still decoding old format.
and the price is not worth for an old technology
for that using HD player to decode and then feed the signal thru HDMI for LPCM, i will look into more details.
Thanks for enlighten me.
Now juz depends on my father whether willing to spend for it o not?
But AVR 2808 is also capable of handling HD signal, i dont mind it is older model as long as the price is rite.
So mind to let me know the current market price for tis babe?

Longmile9,

For 1909, isn't it can decode all HD-Audio by the amp itself right? Therefore not necessary to use PS3 to feed in LPCM. I think it will sound better to bitstream the HD signal & let the amp decodes internally.

You're welcome. Just trying to help. 2808 is good but sorry, i don't know what's the current market price.

Yup, you're right, 1909 can decode HD format. I was only making reference to Multichannel LPCM capability with regards to the 1709 and higher-end Denon models.

As to whether AVR decodes the bitstream or M-LPCM sounds better, i have not done any A/B comparison nor have any experience. I guess it depends on which has the better HD decoder.

AVR-2808 was being sold at near to RM5K mark. Since it is being replaced by 2809, I think it is abt RM4.2K mark

Still so expensive!!
then forget it, either juz bear wif 1709 or if my father wanna get it changed to 1909, then tat will be great.
but anyhow, i still think RM1600 for juz DTS decoding capability nowadays is still overpricing.
I would rather stick to the old Yamaha RX-V361 which also decodes DTS too.
No deny tat 1709 has certain features which should be outperformed RX-V361.
But the price is half of 1709 only. So i think it is not worth.
But wat to do? I father has already bought it home..

Hey guys,

I am thinking that AVR-1709 is able to support True HD-Audio via LPCM from PS3. Looking at the back panel of the amp, it features 8 channels audio input. Correct me if I m wrong, you can use PS3 to decode & then connect all individual speakers channels to these input and you will still receive True HD surround sound........... ?
If not, what are these 8 channels input for (FL, FR, C, SW, SR, SL, SBL, SRL) ?

Well, there is no need to think abt upgrading to 1909 since my father says the price selling here is RM2.9k. need to top up another RM1.3k for tis entry level HD AVR. for RM2.9k n get urself juz an entry level HD AVR, tis is totally not worth for any single cent tat i spend. Wait for the price stable then only get another AVR.

Well, i think tis could be done provided the player can decode the DTS-HD signal to analog for input purposes.
But would it be as good as the AVR itself wif built in DTS-HD decoder?
I mean since it is analog input and the AVR itself has hardware quality restriction, means maybe it cannot reproduce HD signal well (or maybe bandwidth restriction, internal components quality limitation).
Another thing is, compare HDMI signal flow (digitla) from player to RCA (analog) signal, would the signal lost significantly or get distorted due to transfer via analog RCA cable?
And wat is the current blu-ray player that can decode into one-to-one channel (thru RCA) analog input?

I believe the older Sony S300 and the Panny BD50 and BD55.

Panny BD30 cannot decode the BD lossy audio that is why I have to buy the Onkyo 875. Previous AVR is the Pioneer VSX 917.

Another ques, since 1709 is bi-ampable.
so the frequencies produce from Front and surround back/amp assign is same (full range freq)?
or which is producing low freq and which is producing high freq?

My guess would be the same since it doesnt says which is producing high freq and low freq.

Any of u hv tried? is it improved sq significantly?

PS3 doesn't have multichannel analogue outs (only stereo). You can only get the multichannel lossless audio in digital form (PCM) via HDMI. So the receiver must at least can accept multichannel PCM via HDMI (DTS-HD MA/Dolby TrueHD decoder is not needed) if you use a PS3.

If you use multichannel analogue outs (from standalone BD players like Sony BDP-S550 and Panasonic DMP-BD55), you will still get the lossless audio, the only different is that the player already decode and use it's own DAC to convert to analogue. This way, the receiver now works as an amplifier only, usually no further processing is done. But as the interconnect is analogue, you should get a good quality cable to ensure good signal transfer and minimal noise interference.




You mean lossless right? The BD30 can decode all the standard audio except Dolby TrueHD and DTS-HD MA.




Both front and surround will send both low and high frequencies. When either of them connected to the high frequency terminal on the speaker, the speaker will only take the high frequency signal from the receiver. Same thing for the low frequency terminal.

Thanks for answering my ques, but another ques arise.
My lousy speakers do not stated there which input is for high freq and which is for low freq.
If the speakers drivers are linked together internally for woofers, mid and tweeter, so bi-amp it is actually consider double the power input for that speakers? would it cause any harm to speakers?
If I run diff brand n diff quality of cables to speakers, the quality will be affected?
or should i get the exactly same brand n model to run bi-amping?

Good reply from aiman04. Now we get hell a lot better understanding about receiving lossless signal.

Richard, your question each time gets more complicated......

oh really?
juz curious, since i hv read the instruction manual of the AVR.
then ques arises.
acutally i still hv some ques abt auto setup

what if the setup is only 5.1, but AVR capable of 7.1, since the rear surrounds are not utilized we can use it to bi-amp the front speakers... would that improve sound quality from front speakers?

so ppl said it will improve... check ur front speakers support bi-amp or not


btw... HD audio... if u watch unker ho DVD/d-load movie also no point

no need to talk until 5-6k for 1 biji amp
