200W的膽後級,你話重幾多KG呢?

我估唔到

外型夠刹食,上面有位師兄都講咗用開關式電源的其中一個弊處
我都唔明点解會用開關式電源!而且開關式電源所產生的高頻点解決??

INITIAL~D

睇個機身...就知佢係重量級

屋企有乜E郁...都搬唔郁

我說我話: Soulution將音色平衡發揮得淋漓盡致，無話可說，只能講一句，錢多一定要擁有，錢少一定要試聽。

擁有它的必是非富則貴, 唔該請介紹它的主人給我認識啦.

嘗試用我短淺及有限既知識回應你這個問題
線性電源大多需要較為大變壓器，一般都較重及佔用空間，另因為功率晶體管工作在其線性區域，所有的輸出電流必須通過它，亦需要較大的散熱片來消散能量損失，所以線性電源的效率較低 - 50％。

開關電源與線性電源成本較為高些，以往舊式既EMI噪聲比較嚴重，但新一代既MOSFET有重大改良，差不多已經無噪聲，而且比線性電源可以造得更輕巧，最後是開關電源最大既優勢係高效率80％-90％，更少既熱量產生，高熱量不單只浪費能量，亦有機會損害周邊既電子元件。

玩得呢個級數器材,為何仍要聽CD/SACD呢?
梗係黑膠唱盤組會+光悅MC頭喇,
聽Digital Audio,浪費

Some like Digital Audio, I would not say 浪費.  It is a matter of personal choice, although I love TT.  Koetsu carts are good.  It was 1980 or 81, the first time I listen to it " I freaking wanted it, I said..lol.." Backoff cuz it was close to $2k USD.  I bought the Grado Signature Cart instead (was not cheap, over 1k USD lol..) and a Supex MC.  Both sound nice.  Later on, I compared the Koetsu Vs Dynavector Ruby (which I had),  I knew I would never purchased something that fancy unless I win the lotto, lol..

我就懶得調，所以放棄

Not easy to get 50% efficiency on linear P/S, where switching power supply, can get over 90%, not hard.  (my computer P/S is over to 85% efficiency)
I still don't buy the switching noise issue, hehe.  Yes, it could be done with clever design and perfect shielding.  Switching P/S is so much cheaper, but more complex.   I learned about the design of switching P/S, during first year of college but 30 years later, most amps still using linear (AV receiver incl.) that must be a reason, hehe..

Like to share what I know and what I think.  What I say could be wrong at times, hehe.  You know Hi Fi could be very subjective.  I won't laugh at anyone...often I made myself look like a fool,lol..

呵呵！講野就梗係要講自己心中所想所知所聞，人地啱唔啱聽反而其次，又唔係要對住老板，你話係咪
