分析力更細, 音樂更重, 力水相若, 但5009功能全面! 3D support ok!

我其實都現場睇過播Michael Bay 果套講復制技術 (StarWar ObiWan做主角), 仲有雷神奇俠, 真係完全改觀, 好powerful, 人聲同音場非常寬闊, 分析力好像真, 果d玻璃聲撞擊聲同過往嘅安橋聲底有明顯升呢. 我好like呢種聲.

唔知5509前級會唔會進步更多。我考慮緊買部二手5507定依部。差6k

avbaby hing,

可能你好耐無玩過 Onkyo 了. 自 NR905 後 Onkyo 聲低明顯加厚和比以往狠勁.

但係日本仔 AV amp 個後級始終都係太"陽春". 多年來都無大改善. 就算 Denon 跑 bi-amp / bridge 都係得果大力但反應遲鈍. 強烈建議你用鬼佬後級 (at least for front L/R channel).

個人意見先鋒85比90更好,比5009更不用說,安橋產品真的想清楚,
先鋒只是GUI差一點點

insane hing,

I have never seen a Japanese AV amp can push any 4ohm Dynaudio at her desired quality (even Japanese Pre/Power combo). Currently I use Onkyo 906 as AV pre only and only push one Sonus Faber Center. For L/R and rear channel I use separated Krell power amp.

I tried to use LX-82 to drive Dyna focus 110 and Focus centre, the amp self shutdown when some high level voice scene appear and I have phone Pioneer and ask for the reason, they ask me to see the manual and then say that the manual already said that it only guarantee for 6 - 8 ohm speakers, 4 ohm is dangerous, may burn down the speakers or the amp, ask me not to use it. So, I ask why not printing in the manual saying that not support 4 ohm speakers as it may burn down the speakers, then they told me that "there are so many speakers even have 2 ohms, we can't specified all of them".

What a Fxxx!

I am also an Onkyo AV amp owner (not the latest model)

I admit Onkyo top AV amp is quite generous on the power supply and the amplifier section. Yet it probably does not want to guarantee 4-ohm performances. Kindly note that 4 ohm nominal impedence implies that at some frequencies the input impedence can drop below 4 ohm. i.e. I believe there is still possibilities to activate the protection circuits. Of course, there are other dependencies, such as the room size, listening volume, the speakers' input sensitivity etc...

To push 4ohm without burning ur Onkyo amp, u need to apply setup in screen menu. But in bi-amp / bridge mode, 4 ohm is not supported.

Anyway, I tried to use 5009 to push a small Dyna 4 ohm bookselves. Yes the amp is not burnt, but the quality is far below expectation. Ghost power amp is highly recommended for those 4ohm users.

I think we should be fair to the AV amp manufacturers. Speakers with both low impedence (4ohm) + low input sensitivities(<89db) could be demanding to AV amp. Just a rule of thumb that 3db drop in input sensitivity implies roughly double amplifier power to produce similar sound level.

I am using Vienna Accoustic Maestro Grand (Centre), and Waltz Grand (rear channels). These are 4ohm and 91db speakers that live happily with the Onkyo amp in a spacious listening room.
