家庭影院功放到底應該怎么選，照著預算買唄。看似很簡單的問題，但是這里面其實涉及到很多問題，困擾著很多入門小白，今天老蝸牛就來聊聊這個話題，順便解答下幾個相關的常見問題。
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.
選購家庭影院AV功放應該考慮哪些因素?
What factors should be considered when purchasing AV power amplifier in home theater?
在家庭影院系統里，功放機重要的作用就是對聲音進行解碼、修正、潤色、放大，也就要求與音箱功率阻抗匹配、有足夠的功率儲備和聲道數量、功能滿足需求(比如自動房間校正、多分區音樂、或者帶K歌效果器?)、高性能解碼、、甚外觀也要考慮。
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.
別以為設計、外觀不重要，我就遇到過很多用戶選購功放，其他都合適，就是不喜歡那個顯示屏.
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
目前很常見的問題就是商家給一套很貴的音箱，然后搭配一臺很便宜的低端AV功放，小馬拉大車，明顯不可取，遇到這樣的JS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.
同一個系列，老款便宜新款貴，哪個性價比高?
In the same series, the old model is cheap and the new model is expensive. Which one is more cost-effective?
電子產品有一條鐵律，就是建議買新不買舊，對于AV功放這種一年一次更新換代的數碼產品同樣適用。
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.
當然如果是本著追求性價比，或者便宜，可以考慮買舊款庫存，就像iPhone8plus出來三年了，依然有人買。于二手，非熟人的東西千萬慎重，即使是多年老司機，也可能被坑掉底褲，這是一個過來人的忠告
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
同一個企業，老旗艦和新中高 檔，差不多買哪個?
The same brand, the old flagship and the new high-end, the price is almost buy which?
如果你手上有后級，就建議考慮新款，它的解碼技術會更新、更成熟，比如對8K超 高清視頻的支持，各種新的音效模式的支持和優化，算法升級等等，可以帶來更多前沿技術的體驗。
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 端貨勝在整體架構更強，用料更足，放大器部分性能也更好，它能給你帶來更豪華的享受，當然，如果老到對HDMI都支持得不是很好那種的話，就不值得考慮，畢竟這已經不是代溝的問題，屬于跨時代了。
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.
