Pass Labs INT只有一個Model,但有30A Class A 30w x 2和 150 (Class A / AB) 150w x 2两款,以前Threshold SA-3 推B&W DM 17書架效果無人話無力,INT 150在數 w以內都係Class A,所以都勁熱,和本人X600.5一樣,Pass Labs 上一級就是要前後級了,後級是XA30.5。
Luxman 合併分別有550,570和590,590是Luxman合併Top model,亦分590A Class A ( 30w x2)和590u Class AB (120w x 2)。
美國機和日本機最大分別就是力感,其次Luxman 590AX已是590的第三代。
Luxman 590AX : 556500Yen x 0.092 = ~HK$ 51,198-
Pass Labs INT 30A/150 : US$ 7150 x 7.77 = ~HK$ 55,555-
Pass x350 - 350w
first 50w is class A but not pure class A.
front is current meter, when the meter does not move, it means i am using class A.
when i set the volumn over half, the meter still not move.
therefore i even does not use up 50w class A most of the time.
when i used to paly with my very old Infinity Kappa 9 speakers(each channel 7 units, 2 of them are 12" woofer). this monster can drop the ohm down to 0.7ohm. The meter is still not move most of the time.
so even 30w class a is good enough to push normal speakers in 150ft2 area.
