最近回国带回来一个硬盘式的卡拉ok机器。虽然可以直接接上电视演唱，不过想想还是
配上功放和音箱要效果好些。从来没买过这些东西，请教一下买哪个经济实惠，性价比
高啊。两个加起来最好在300刀以内吧。咱一点都不了解行情。
谢谢先了。

有个贴和我的观测相符. ios 6+xcode4.5 的性能下降很多。
难道apple强迫淘汰老机器？

"Hi there,
I am developing games not with Unity, but with a home-made 2D OpenGLES non-
GLkit (no shaders) engine. I thought I'd add some results just to confirm
this is not a Unity-only problem.
Both the transitions from iOS 5.1 to 6.0 and from xcode 4.41 to xcode 4.5
lead to a drop in fps in my game.
The memory and cpu requirements of this game are negligible.
-iphone 4 iOS 5.1 to iphone 4 iOS 6.0, built with Xcode 4.5 shows an average
fps drop of 25%.
-xcode 4.5 to xcode 4.4.1 on an iphone 4 with iOS 6.0 shows an additional
fps drop of 10%.
-xcode 4.5 to xcode 4.4.1 on an iphone 4 with iOS 5.1 shows an additional
fps drop of 5%.
Basically this means that having iOS 6.0 on a 4 and running an app compiled
with xcode 4.5 will seriously change performance.
At first I thought this was due to the new performance analyzer that runs
during xcode 4.5 debugging, but release builds showed similar fps
differences.
Thanks, I'm glad I'm not the only one with this problem.
PS: No it is not silly to upgrade an iPhone 4 to 6.0 because that's what the
customers will do."

电脑怎么output到家里的5.1或者更强的音响系统？
接口不一样，要通过receiver?

你的5.1或者更强的音响系统，是什么带着的？不是receiver吗？
看看你的系统有哪些输入可用，看看电脑有哪些输出，找个一致的连起来就好了，比如
optical, digital coax, 或者hdmi也有可能

声卡支持同轴或者光线就可以连接到receiver了。
