The combo pairs amazingly well with the existing Topping A90/D90 flagship desktop audio chain.\n\nPremium NFCA Module:-\n\nEquipped with a premium NFCA(Nested Feedback Composite Amplifier) module just like the flagship Topping A90 amplifier, the Pre90 delivers an outstanding performance. It also features Voltage Current Hybrid Feedback Architecture and Ultra-High Gain Feedback providing noise and distortion-free signal amplification for weak audio signals.\n\nUltra-Low Noise Floor:-\n\nThe Topping Pre90 features a high-performance chipset that provides an ultra-low noise floor of less than 0.3uVrms. The output has a high dynamic range of up to 145dB, ensuring noise-free sound output with a rich dark background for its users.\n\nConnect Multiple Inputs At Once:-\n\nWith the help of Topping Ext90, you can connect multiple sources with the Pre90 at once. On itself, the Pre90 features one single-ended RCA and one balanced XLR input but with the Ext90, it can be connected with up to two RCA inputs and four XLR inputs. The active input source can be selected easily using the included remote control. Moreover, the Pre90 remembers your volume settings for different input/output ports so be assured of that too!!\n\nSafe Volume Feature:-\n\nThe Pre90 features a safe volume option that kicks in when the set safe volume exceeds the target input/output port. It saves up your costly pieces of equipment from damage due to sudden high volumes. This feature can also be turned off from the settings menu u","images":["https://cdn.shopify.com/s/files/1/0031/0453/8673/products/topping-pre90-ext90-rca-cable-hifigo-177873.jpg?v=1655187884","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/topping-pre90-preamplifier-topping-ext90-input-extender-nfca-modules-hifigo-865861.jpg?v=1607408953","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/topping-pre90-preamplifier-topping-ext90-input-extender-nfca-modules-hifigo-968953.jpg?v=1607408891","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/topping-pre90-preamplifier-topping-ext90-input-extender-nfca-modules-hifigo-920423.jpg?v=1607408902","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/topping-pre90-preamplifier-topping-ext90-input-extender-nfca-modules-hifigo-659662.jpg?v=1607408959","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/topping-pre90-preamplifier-topping-ext90-input-extender-nfca-modules-hifigo-556292.jpg?v=1607408997","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/topping-pre90-preamplifier-topping-ext90-input-extender-nfca-modules-hifigo-153068.jpg?v=1607408986","https://cdn.shopify.com/s/files/1/0031/0453/8673/products/topping-pre90-preamplifier-topping-ext90-input-extender-nfca-modules-hifigo-750225.jpg?v=1607408880"],"price":599.99,"currency":"USD","in_stock":true,"inventory_qty":59994,"dynamic_pricing":false,"listed_at":"2026-06-20T16:26:31.510Z"},"share_url":"https://firestarter.network/l/lst_o4culjsm","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
