大家有冇聽過First Watt 這個牌子?

Rontam

好似係PASS LABS的副品牌,定係創辨人的新牌子?

有。
It is the Nelson pass private project. (SIT 2, M2...)
In the Stereo  Sound , it has very good comment . If my memory is right, it got a 1st in the place at  its own price range.
It is a very good AMP but it needs to have a very high efficiency SPK to match (>97 db)

好有興趣 不過上雅典都無得聽 細屋聽小品野OK

我出兩個月左右上去完全無DISPLAY 不過一定係雅典代理 可能FIRST WATT平唔啱中環客

部J2又真系好抵玩的，好似定兩萬八，D人買條線都分分鐘吾只。但新的SIT－1就好貴，見定價都US5000一部，仲有要找10watt就玩得又全面的喇吧真係有D難。。。。

請問J2聲音如何?同PASS LABS純A類點比?

須然兩萬八但佢嘅評價就

如果不須要大Power,咁J2未超底玩!

我覺得應同其它chip amp比如gaincard。我無聽過pass a類，但chip amp的特性係線路簡單，聲音會是非常快速，靈巧，直白（相對a類）。

J2 with 30W per channel at 8 ohms looks like a second-line version of PassLabs XA30.5

J2 with list price of USD4200 is about 30% cheaper than XA30.5 (appears to be good value for money although J2 front panel has no meter display)

mahi 兄，好利害。它和 GainCard 確有相儀地方。都是非常音樂感！！！

First Watt 好力啲，GainCard 幼細啲！

Nelson Pass認為後級輸出最重要是第一瓦輸出,會直接影響其後2,3,4......瓦輸出的聲音,所以命名為First Watt,此品牌名是有意思的,本人真的很佩服Nelson Pass的研究精神,而價錢公道,不會收天價,另我們一班發燒友得益不小!

想補充其實應該最近所有firstwatt都係行class a的，係好鬼熱的，我之前說比較直白是指跟一般class a聲比較。

另passlab amp好似係用mosfet。

咪玩啦，邊夠你利害！

其實事源都係有friend想買gaincard而又有友人介紹他聽埋j2遮，所以我先知小小。

The amps for first watt would use different transistors. The j2 used only one JFET.
The output characteristic curve very like SET tube machine. When the impedance of the loudspeakers  going down the output was not going down too. It is not like other transistor machine.
.
If your speakers  have low efficiency and very low impedance , you might have trouble to drive it with first watt j2.
.
Nelson Pass matched the j2 with high efficiency horn loudspeakers.

有冇師兄知道部J2係咪一定要上代理試?出面好似唔多見有

frankie7899

出面應該冇,去代理試好過啦!

各位師兄知唔知FirstWatt之前係咪出過一部前級架?
