如果部機好聲耐用己是環保，因為你不會強迫自己去換機和製造垃圾！

真正唔環保係買咗唔好聲加上唔耐用嘅機，即係變相製造垃圾！

We should look for environment friendly way to enjoy music. I believe there should be way to product high end amp which is energy efficient and better than Class-A. In fact, some class-a amps are not sound that good either.

In the old days, manufactures have to say and make Class-A amp better as they are very good profit margin. Taxation and regulation and consumer buying criteria will push manufacturer to invent and push good alternatives. I won't be surprise that some manufacturers suddenly say other amp design is even better.

electronic is an adjective.

there was no mistake.

"do you mean the electronics or electricity travelled slower in the olden days than now?"
- electronics travelled??????????????? What were you asking?

What do your questions mean then?

"i was asking about "electronic" or electronics/electricity. not bandwidth or clock speed, current gains. if you cannot see the differences i cannot help in this regard."

If you are unable to notice the mistakes you made, then 巧言令色.

＞＞所有"膽"機仍以A類形式運作，談不上環保！
PP膽機可以做A類及AB類!!
不能只計能源效益,一火的膽機可能比200火的D類省電!!

i was asking about "electronic" or electronics/electricity. not bandwidth or clock speed, current gains. if you cannot see the differences i cannot help in this regard.

maybe, we can give the amp some component for supporting, thats 環保 and more efficient. such as Cryogenic Treatment http://www.sineworld.com/html/cryo.html
not only can improve the sound for WHOLE thing, but also save $$.
I read more english magazine to say this points. ( even my english is primary school level )

cpu8088,

Speed of signal bandwidth is different from speed of electron movement. Bandwidth of electronics device has been increased a lot for the pass three decades. While comparing Intel 8088/8086 (in the old day) and Intel Quad-core (nowaday), you must see the difference. The clock speed is increased a lot, from the order of MHz to GHz.

For example, a lot of power transistors have much larger current gain bandwidth product than 3055 being used in some of the vintage amplifiers.

These days, there are less straight class A hi-end amps but there are still a few examples I can think of: Pass Labs XA series, Lamm, Gryphon, Jadis.

I don’t think in Europe (or any non-authoritarian country) that there would be law to band certain classes of consumer technology. More likely other measures such as taxation and regulations to discourage wastes would be used.

"""Today's electronic is highspeed, so the power can be generated instantly."""

do you mean the electronics or electricity travelled slower in the olden days than now?

and the power from power plants different for coal firing and nuclear generated?


"""So it does not requires "on" all the times."""

i would have thought the always on is related to shortening the time for warm up. even class a amps can be switched off when not in use.

agreed. no one is perfect.

＞＞＞a. I have 300B , and class D amp both

所有"膽"機仍以A類形式運作，談不上環保！

the most envoironmental friendly shall be UNPLUG, back to basic.

But Now, which Class D amp can totally win Class A amp?

不環保 shall be over 2000cc or turbo car and they should be ban.

Sing!! it's most environmental friendly way of music making.

上面只結他要斬樹才做到喎!咁都算環保?ka.ka.ka

I used to have a Class A amp too.

But I don't think it is as good as Class A/B amp in speed.

Today's electronic is highspeed, so the power can be generated instantly.

So it does not requires "on" all the times.

This is 環保:

靚聲 + 環保...

童虎 Hing,

Agree with you, even I am using class A/B amp.

玩Hi-Fi只求靚聲，環保、浪費電力，不是我的考慮！
