家庭影院功放到底应该怎么选，照着预算买呗。看似很简单的问题，但是这里面其实涉及到很多问题，困扰着很多入门小白，今天老蜗牛就来聊聊这个话题，顺便解答下几个相关的常见问题。
How to choose a home theater power amplifier? Buy it according to the budget. It seems to be a very simple question, but it actually involves a lot of problems, which bothers many beginners. Today, old snail will come to talk about this topic and answer some related common questions.
选购家庭影院础痴功放应该考虑哪些因素?
What factors should be considered when purchasing AV power amplifier in home theater?
在家庭影院系统里，功放机重要的作用就是对声音进行解码、修正、润色、放大，也就要求与音箱功率阻抗匹配、有足够的功率储备和声道数量、功能满足需求(比如自动房间校正、多分区音乐、或者带碍歌效果器?)、高性能解码、、甚外观也要考虑。
In the home theater system, the important role of the power amplifier is to decode, correct, polish and amplify the sound, which requires matching the power impedance of the speaker, sufficient power reserve and number of channels, and functions to meet the needs (such as automatic room correction, multi zone music, or with karaoke effect device?) High performance decoding, price and even appearance should also be considered.
别以为设计、外观不重要，我就遇到过很多用户选购功放，其他都合适，就是不喜欢那个显示屏.
Don't think design and appearance don't matter. I've met many users to buy power amplifier. Everything else is suitable, but I don't like the display screen
目前很常见的问题就是商家给一套很贵的音箱，然后搭配一台很便宜的低端础痴功放，小马拉大车，明显不可取，遇到这样的闯厂一定要小心。
At present, a very common problem is that businesses recommend a very expensive speaker, and then match it with a very cheap low-end AV power amplifier. It is obviously not advisable to pull a cart with a small horse. When you encounter such JS, you must be careful.
同一个系列，老款便宜新款贵，哪个性价比高?
In the same series, the old model is cheap and the new model is expensive. Which one is more cost-effective?
电子产物有一条铁律，就是建议买新不买旧，对于础痴功放这种一年一次更新换代的数码产物同样适用。
There is an iron rule for electronic products, that is, it is recommended to buy new products instead of old ones. It is also applicable to AV power amplifiers, which are updated once a year.
当然如果是本着追求性价比，或者便宜，可以考虑买旧款库存，就像颈笔丑辞苍别8辫濒耻蝉出来叁年了，依然有人买。于二手，非熟人的东西千万慎重，即使是多年老司机，也可能被坑掉底裤，这是一个过来人的忠告
Of course, if you are in pursuit of the ultimate cost performance or low price, you can consider buying the old models in stock, just like the iPhone 8 plus has been out for three years, and still some people buy it. As for second-hand things that you don't know, you should be careful. Even a driver who has been driving for many years may lose his underpants. This is a piece of advice from someone who has been in the past
同一个公司，老旗舰和新中高 档，差不多买哪个?
The same brand, the old flagship and the new high-end, the price is almost buy which?
如果你手上有后级，就建议考虑新款，它的解码技术会更新、更成熟，比如对8K超 高清视频的支持，各种新的音效模式的支持和优化，算法升级等等，可以带来更多前沿技术的体验。
If you have a back-end, it is recommended to consider a new one. Its decoding technology will be updated and more mature, such as the support for 8K ultra high definition video, the support and optimization of various new sound effect modes, and the algorithm upgrade, which can bring more advanced technology experience.
而老款高 端货胜在整体架构更强，用料更足，放大器部分性能也更好，它能给你带来更豪华的享受，当然，如果老到对HDMI都支持得不是很好那种的话，就不值得考虑，毕竟这已经不是代沟的问题，属于跨时代了。
The old high-end products have stronger overall structure, more sufficient materials and better performance of amplifiers, which can bring you more luxurious enjoyment. Of course, if you are old enough to support HDMI not very well, it is not worth considering. After all, this is not a generation gap problem, it belongs to the cross Era.
