quem confirma isto?
depois disto tudo fiquei curioso, e como ainda não tenho BR, pelos vistos quando o comprar terei de ter em atenção algumas coisas.
se alguém confimar isto que retirei do avforuns e do engadget, então posso ter som HD no meu marantz
gostava mesmo de saber a vossa opinião sobre isto, e espero que desta vez não seja mal interpretado e não venham dizer mal de mim
"Decompressing in the player
Home theater amplifiers don't evolve at the same rate as other electronics, and usually an amp that was good five years ago is still good today. So we understand that people can be hesitant to replace their AV receiver just to listen to the latest codecs. Luckily, most older receivers still have HDMI (pre 1.3) or discrete analog inputs (6 or 8). For this reason, having an HD movie player that can decode internally is advantageous, as it will handle the latest codecs and allow your older amp to just take the signal and amplify it for your speakers. The other advantage to decoding in the player is that if discs were authored with the advanced authoring method, the player can mix interactive feature's sounds with the regular audio from the movie -- things like beeps from the menus and directors commentary can fall into this category. If you decode in your AV receiver, you won't be able to take advantage of the additional sounds."
"As long as your amp can handle PCM then your able to get the full benefit of the HD audio tracks on either bluray or HD DVD.
There is no benefit sonically to having the soundtrack decoded in the amp if it is decoded in the amp then some of the discs features may not be available .
The discs are authored so that they can only be decoded in the player itself.
both DTS HD and Dolby HD are just loseless methods for compressing the original soundtrack. Sonically all will be the same as they are loseless.
Whatever way you decode the signal in the amp or in the player the end result is a PCM signal.
No benefit to be had whatsover from amps marketed with Tru HD etc etc and certainly no more future proof than anamp that can handle PCM"
"Virtually EVERY receiver will accept all of the new sound formats, as long as it has multi-channel analog inputs and that the player has MC analog outputs and internally decodes. Some prefer the new sound formats over HDMI, and some prefer the receiver to internally decode.
There are 3 ways to get high resolution audio...
1. 6 to 8 Channel Analog Connection
In this scenario, the high definition player will output TrueHD/DTS-HD Audio through the analog outputs of the player to your AV Receiver. The TrueHD, DTS-HD Master Audio or DTS-HD High Resolution will be decoded by the player and sent out as analog audio signals to the AV Receiver. You would Simply connect 6, 7, or 8 RCA cables from the analog outputs of the player to the analog inputs on your AV Receiver. The number of analog cables will be determined by the number of analog output/inputs on the player and receiver. The analog signals will go directly to the receiver's amplifier section. In this way you can enjoy TrueHD/DTS-HD Master Audio that is bit-for-bit identical to the studio master.
2. HDMI 1.1 or 1.2 Connection
In this scenario, the high definition player would output the audio as an uncompressed 6 to 8 channel linear PCM digital audio stream. You will need a player with a built-in TrueHD/DTS-HD Decoder, and both player and AV Receiver need to include HDMI version 1.1 or 1.2* outputs/inputs. HDMI stands for High Definition Multimedia Interface, and is a single-cable connection designed to accommodate digital multi channel audio and video. Simply connect the HDMI cable from the output of the player to the HDMI input of the AV Receiver. The DTS decoder inside the AV Receiver will "ignore" the Linear PCM stream and pass the audio stream on to your receiver's digital-to-analog converters and then on to the 5.1 or 7.1 amplifier. This way you can enjoy TrueHD/DTS-HD Master Audio that is a bit-for-bit identical to the studio master.
3. HDMI 1.3 Connection
You can enjoy TrueHD/DTS-HD Master audio by upgrading to a Blu-ray Disc or HD-DVD player with TrueHD/DTS-HD Advanced Digital Out and new AV Receiver with TrueHD/DTS-HD Master Audio decoding. Simply connect the player and receiver with an HDMI cable. The DTS-HD bit stream will pass through the player and HDMI cable to be decoded by the AV receiver. Both player and AV receiver will need to be equipped with new HDMI Version 1.3* outputs and inputs. This way you can enjoy TrueHD/DTS-HD Master Audio at up to 7.1 channels at 96 k/24 bit sound that is bit-for-bit identical to the studio master."

Sim, se comprares um leitor que faça a descodificação dos formatos TrueHD e DTS-HD e que tenha saídas analógicas individuais para cada canal, basta ligares essas saídas ao Multi-Channel input do amplificador. Como vai apenas um canal de som por cada cabo, acho que não há problemas de largura de banda.

Alguém ??
E já agora, a diferença desse yamaha para o tão falado onkyo 606 é muita? Em que por exemplo? (tenho noção que se calhar estou a fazer uma pergunta ridícula, mas n percebo muito disto :s)

tens toda a razão, neste .pdf da própria Dolby http://www.dolby.com/assets/pdf//tech_library/TrueHD_FAQ_10925_Final.pdf
os pontos 24 & 25 da 2ª página confirmam o que dizes.

Que acham das colunas Harman Kardon HKTS 11 para juntar com o Onkyo 606?

Não, ainda n tive oportunidade. Para já ando a tentar descobrir a nível teórico a diferença entre os sistemas e a ter uma ideia do que vou procurar quando for à loja.
Tenho lido basntante sobre isto e o onkyo 606 é sempre bastante recomendado, mas o preço dele ainda é um bocado alto para o q tava a pensar. O que não qer dizer que se valer a pena n opte por ele. Por isso é q tava a perguntar o q é que este av onkyo tem a mais que aquele yamaha (o yamaha foi apenas um exemplo)? Qualidade de som? saídas e entradas? descodificadores de som? ERa isso q gostava de saber.

Boas, hoje tive a ler este tópico, por acaso tb estou bastante inclinado para comprar as Kef 2005.3, hoje mesmo tive a falar com a ***** eles dizem que o prazo de entrega é de 2 semanas. Já agora sabem onde posso comprar os suportes para essas KEF 2005.3 e qual será o preço ?
Em relação ao amplificador, sem dúvida preço qualidade neste momento é o Onkyo 606 mas como tenho 1 denon ainda dá para os gastos, entretanto de certeza saiem modelos novos.

se os suportes das 2005.3 forem iguais aos das 2005.2, o sitio mais barato que encontrei foi na *****

olá a todos!
Qero comprar um receiver A/V, só ainda n sei bem o que comprar. Eu tenho umas colunas KEF (do tipo coluna), que estava a pensar aproveitá-las para a frente que embora sejam um pouco antigas até gosto do som delas. A minha dúvida é se valerá a pena este aproveitamento.
Então, o que qeria pedir é que até 500/600€ me indicassem um sistema que possa montar com obejectivo de ligar a tv, ps3, dvd, media center,...
-Podem ser sistemas completos com colunas, no caso de acharem q não vale a pena aproveitar as KEF.
-sistemas composto só pelo A/V se acharem q para já so vale a pena comprar o A/V e dpois ir comprando o resto.
-ou sistemas compostos por A/V, + coluna central + surr.
Obrigado
