呢部解碼同個擴音外型一樣，俾我們可能會攪唔清楚邊部打邊部喎！

惟有睇個音量制

最緊要要啱自己

Top of the line parts and construction.  It is a thing of beauty and top engineering.  I wouldn't criticize about heat or compare them to other brand without actually listening first.

在為數不多的德國Hi-End音響廠家中，T+A可以說是一個非常獨特的廠家。精確嚴謹是發燒友的第一印象。 T+A  ...

嘩, 咁出色的功放, 可以試聽就好囉

好棒的組合，德國的工藝向來都很紮實，就是不知道聲音能有多好的表現~

This particular amp does not have the best reviews in the U.S.  Generally positive though.  I would consider this is a mid-level high end gear.  Mainly because of it's high voltage operation and large current out-put, well build too.  PA-3000 HV的輸出級的電壓設定在+/- 160伏特，這個工作電壓大約比一般正常晶體放大線路高出一倍...That is good and bad...320Volts of total voltage is just like a tube amp...lol..and scary .  First time in my life to see solid state works at this hi voltage @ 60amp max current.  Tons of dynamic headroom/heat, easier to design (harder to build) but scary...This is just technical aspects of my opinion, which has nothing to do with actual listening sessions.

補充內容 (2014-2-27 07:26):
P=VI The most basic relationship between power, voltage and current, assuming 100% efficiency.  Say if it is 50% efficiency, rest of 50% will become heat. Therefore, hi voltage, hi current means more heat is not an assumption if not 100% efficiency unless someone rewrites the theory.

師兄真的對這些HIFI產品很了解，如果小弟之後想組套設備，放在影音室，那一定會上來請教一下師兄的意見，多謝師兄了~

Not really, I retired from hi fi for few years until recently.  Fortunately, it wasn't much changed from over 30 years ago to now.  Lots of brands that I was familiar with are now history.  Other than that, parts and designs are basically the same regardless of how beautiful the reviewers adjectives are.  Not too hard to pick it up again over the last few months.

I love hi fi and why I  spend 5 years in college specialized in audio design when I was young.  Hoping to be an audio designer.  H.P. hired me so I switched to computer business lol....and never touch audio design again.  Just wanted to share something I learned and hi fi experience with fellow members.  There are things I don't know and learn here too...

師兄客氣了，那怕好幾年沒研究，小弟相信師兄的眼光及經驗，更何況如師兄說的，HI FI的改變並不大~~
