Five months later, the A-75 was announced with 2 x 60 W into 8 \u03a9 in pure Class A. Since then, integrated amplifiers have continued to grow, culminating in the E-800 (2 x 50W in class A) and E-5000 (2 x 240 W in class AB). So Accuphase needs to demonstrate a new interest to prefer separate components, which must inevitably move upmarket. The successors to the A-75 and P-4500 take 5 W respectively with the A-80 and 60 W with the P-4600, the latter peaking at 450 W under 2 \u03a9, compared with 360 W previously for the P-4500. Based on six parallel output stages per channel, the P-4600 also boasts an 18% noise reduction for a signal-to-noise ratio of up to 125 dB. Fully symmetrical, it improves its damping factor by 100, from 700 to 800.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1920\" height=\"1089\" src=\"https:\/\/vumetre.com\/en\/wp-content\/uploads\/2023\/11\/Accuphase_P-4600.jpg\" alt=\"\" class=\"wp-image-2291\" srcset=\"https:\/\/vumetre.com\/en\/wp-content\/uploads\/2023\/11\/Accuphase_P-4600.jpg 1920w, https:\/\/vumetre.com\/en\/wp-content\/uploads\/2023\/11\/Accuphase_P-4600-1280x726.jpg 1280w, https:\/\/vumetre.com\/en\/wp-content\/uploads\/2023\/11\/Accuphase_P-4600-980x556.jpg 980w, https:\/\/vumetre.com\/en\/wp-content\/uploads\/2023\/11\/Accuphase_P-4600-480x272.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) and (max-width: 1280px) 1280px, (min-width: 1281px) 1920px, 100vw\" \/><\/figure>\n\n\n\n<p>A-80<br>For its part, the A-80 gains 5 W at 8 \u03a9, 10 W at 4 \u03a9 and 20 W at 2 \u03a9. Also perfectly dual-mono, it reduces its noise by 7% compared with the previous generation, reaching a level of 16.1 \u03bcV, still 3.4 \u03bcV lower than the P-4600. Its damping factor is guaranteed to be on a par with that of the big A-300 mono block and the E-800, i.e. at least 1000, while power is developed by 10 MOS-FET output stages per channel in parallel. Numerous other improvements have been made to both products, and our first glimpse of the P-4600 impresses us with its contained power, which was higher than that of the E-5000 in our first musical impressions, despite the lower advertised data.<br>We hope to be able to tell you more about it in our next test drives!<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Having recently launched the C-2300 preamplifier, replacing two series of preamplifiers in its own right, Yokohama manufacturer Accuphase is now renewing its power amplifiers, and at the same time presenting a new class A and a new class AB, both more robust than the previous series.
