{"type":"firestarter.listing","listing":{"id":"lst_hAMMM5o2","product_name":"TOPPING DX5 II DAC/Amp","category":"Headphone DAC/Amp","description":"\nA big upgrade for a proven performer\n\nThe DX5 II is TOPPING’s new fully balanced DAC and headphone amp combo. With upgraded internals, broader connectivity, and user-focused improvements, it builds on the DX5 without reinventing the wheel. Dual ES9039Q2M DACs provide the decoding core, while an all-new X-Hybrid amplifier circuit drives your headphones, plus the updated Aurora UI and PEQ system offer precise and powerful sound tailoring. \n\nNew dual DAC design\n\nTwo ES9039Q2M chips handle digital conversion—one per channel. That means lower crosstalk, better imaging, and an improvement in specs: 133dB SNR, 133dB dynamic range, and distortion as low as 0.00006%.\n\nX-Hybrid headphone amp circuit\n\nThe DX5 II replaces the NFCA module with an original triple-stage hybrid amp circuit. It uses a discrete input stage, op-amp gain stage, and discrete output stage. The result is high efficiency, improved thermals, and precise delivery at every volume. Power output peaks at 7600mW x2 into 16Ω—more than enough for basically any headphone.\n\nBalanced audio in a compact case\n\nWith a quad-channel fully-balanced headphone amplifier, the DX5 II fits serious hardware into a small chassis. It offers 4.4mm balanced, 4-pin XLR balanced, and 6.35mm single-ended outputs. \n\n10-band high-precision PEQ\n\nThe desktop software lets you tweak 10 independent frequency bands—adjusting frequency, gain, and Q-factor. Save multiple profiles, apply different EQ to your speakers and headphones, and import and export curves. \n\nAurora UI\n\nA 2.0\" full-color screen, a pressable knob, and three buttons make for quick, clear control. Change your background color. Choose between FFT, VU meter, or playback info display. Assign the knob to control whatever you use most. \n\nWireless support with LDAC\n\nBuilt around the QCC5125 chip, the DX5 II supports Bluetooth 5.1 with LDAC, aptX HD, aptX Adaptive, AAC, and SBC. You get up to 96kHz/24-bit streaming without cables—useful for TV, tablet, or streaming box connections.\n","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890122.jpg?v=1749248688","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890141.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890140.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890139.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890138.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1172405642.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890136.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890135.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890134.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890133.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890132.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890131.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890130.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890129.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1172405641.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890127.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890126.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890125.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890124.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890123.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1174224771.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1174224772.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890121.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890120.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890119.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890118.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890117.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890116.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890115.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890114.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890113.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890147.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890146.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-topping-headphone-dac-amp-topping-dx5-ii-dac-amp-1171890152.jpg?v=1756911852","https://cdn.shopify.com/s/files/1/0225/2721
