The main reason for this increase in weight is that the GaN power supply has been redesigned into two independent symmetrical blocks (75 \u00d7 30 \u00d7 25 mm) in a sophisticated two-phase interleaved GaN power factor correction (PFC) circuit. This approach provides very strong voltage regulation while maintaining minimal noise levels and achieving ultra-high efficiency. The entire PFC module now offers an output power of 600 watts, fed back to a Class A input stage and a Class D switching MOSFET circuit capable of operating at up to 600 Hz, with a 30% reduction in operating temperature compared to the previous model.<\/p>\n\n\n\n<p>The input stage combines an ultra-linear class A module (ULCAM) with Nichicon KZ MUSE input coupling capacitors specially selected for their ability to deliver neutral, pure sound. OS-CON capacitors are used in the asymmetrical Class A modules to ensure stable, high-quality signal coupling, while the ultra-low-noise input stage also uses JFETs to achieve the lowest possible background noise and ensure signal integrity from the first amplification stage. The IDA-9 also incorporates 14 WIMA MKP and EPCOS MKP series capacitors throughout the circuit for power rail bypassing. The final power output of the unit is rated at 2 x 200 W RMS into 8 \u03a9 and 2 x 250 W into 4 \u03a9.<\/p>\n\n\n\n<p>On the preamplification side, the volume is controlled in 99 steps of 0.5 dB, and a pair of analogue inputs sits alongside four optical and coaxial digital inputs, plus two USB ports, one of which can accommodate a WiFi and Bluetooth receiver module. Via USB, files can be decoded at rates up to 384 kHz in PCM and DSD256; DoP is also supported.<\/p>\n\n\n\n<p>Already available, the IDA-9 is launched at a retail price of 1 599 \u20ac.<\/p>\n\n\n\n<p>08\/28\/2025<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1058\" height=\"519\" src=\"https:\/\/vumetre.com\/en\/wp-content\/uploads\/2025\/08\/IDA-9_black_2.jpg\" alt=\"\" class=\"wp-image-4383\" srcset=\"https:\/\/vumetre.com\/en\/wp-content\/uploads\/2025\/08\/IDA-9_black_2.jpg 1058w, https:\/\/vumetre.com\/en\/wp-content\/uploads\/2025\/08\/IDA-9_black_2-980x481.jpg 980w, https:\/\/vumetre.com\/en\/wp-content\/uploads\/2025\/08\/IDA-9_black_2-480x235.jpg 480w\" sizes=\"(min-width: 0px) and (max-width: 480px) 480px, (min-width: 481px) and (max-width: 980px) 980px, (min-width: 981px) 1058px, 100vw\" \/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Tested in our VU Meter #1, the IDA-8 is being replaced 10 years later by the IDA-9.
