The most famous American amplifier brands are MARK LEVINSON, KRELL, JEFF ROWLAND, CELLO, VIOLA, PASSLAB, MCINTOSH, AYRE, AUDIO RESEARCH, HARMAN KARDON, etc. The characteristic of American power amplifiers is that there is no sound coloration. The world's famous sound comes from Europe and the United States, and it is well deserved. Although the nominal output power is 100W, this is a characteristic of American power amplifiers. It is not exaggerated, or even a little reduced. In fact, although it sounds There is still no distortion at the loudest sound, but in a room 20 meters away, it does not need to be turned to more than half the volume. It is no problem to push an 8-inch box. Many speaker sellers use Harman Kardon amplifiers for sound testing.

Because the Japanese have advanced technology and the advantage of mass production, the current Japanese power amplifiers not only have exquisite appearance, but also have certain advantages in performance-price ratio. In the past, Japanese power amplifiers, influenced by traditional music such as "gaku", often placed too much emphasis on high and low frequencies and had a stiff tone, so they were jokingly called a big drum plus a triangle. However, now the excellent products produced by some famous Japanese companies have paid more and more attention to the balance of the amplifier's tone, and the details are also very clear. Among high-end products, some products such as Golden Throat (Accuphase) are enough to put European and American products to shame; in mid-range products Among the products, a large number of products such as Denon's PMA-2000, PMA-S1, PMA-S10, Sony's TA-FA5ES, F-5000, Onkyo's Intergra A-927 and Pioneer's A-05 have shown aggressive performance. momentum. Among mid-to-low-end Japanese products, although the sound quality is still stiff, if compared with European and American products at the same price, Japanese products often appear to be great value. In terms of matching, if you use a mid-priced Japanese power amplifier and European and American speakers (such as Denon and Kef, Yamaha and B&W) to complement each other in performance, then there will be a satisfactory effect in terms of tone.
