都應該唔係。
佢好得意，睇成果收錢的。

講堅，其實如果係你，你會比幾多錢去買你手上條避孕線？
可以唔使比臉我，照直講，咁我先可正確 ACCESS 到條 UPGRADE 應值幾錢。

Denon POA 4400.....日本制造之Passlab.....




"DENON's Reference-Class POA-4400 monaural power amps
that have earned high marks from audiophiles and critics
throughout the world. This affordable yet luxurious
monaural power amps with its Dual Super NON-NFB circuit
(The Nelson Pass 'Stasis' design, and were built under
licence from Threshold) delivers high power while
preserving even the most delicate nuances of high-quality
digital sound sources."

Being a monoblock, each unit provides dedicated
amplification to a single channel. This design
provides significant advantages over regular
multichannel design. Since the power supply and
amplification circuit is completely dedicated
for each channel, you get excellent sonic quality
and headroom till the rated power of 150 watts.
Multichannel amplifiers often are unable to provide
full output to all channels to once. The advantages
of the monoblocks seem to be that you can place each
amp very near to the speaker it drives, thus much
shorter speaker cable, and the quality of the
sound should be improved since there is no interaction
between the two channels in the amplifiers.

The POA-4400 are a Nelson Pass 'Stasis' design, and were built
under licence from Threshold. They are MOSFET class 'A' amps which
put out about 150 Watts each.

Stasis amps use a low current fixed bias class A voltage amp
to supply voltage gain. The output stage supplies the current
necessary to 'prop up' the voltage swing of the voltage amp. Again
Threshold claimed this allowed the sonic benefits of class-A without
the heat of true high power class-A amps.

Class a但又一d都唔熱。150w 係8ohms, 咁4ohms 係咪300w?

咁先至係高手線路!

係4ohm 300w

明白。6600有d好難像它的抱牙。damping 唔知有幾大。

    一般class a damping 唔會好大'佢係用大電流去驅動喇叭。而日本仔做嘅pass 線路聲音比美制更通透

    ic. 唔怪得前輩介紹d amp比我多數都係class a啦。dyna要既係電流？
