Topping has made a big name for itself in the desktop audio scene. The brand is regularly praised for its great sounding desktop gears available at almost every price segment. They start at entry-level products and goes as high as flagship-grade products. Today, we are here to discuss one of their upcoming flagship-grade product, a flagship headphone amplifier and Pre-amp, presenting you all the brand new Topping A90 Discrete.
A90 from Topping has been leading their range of desktop headphone amplifiers with its exceptional performance. With the latest A90 Discrete, Topping is introducing a fully-discrete design for its famous NFCA module. NFCA(Nested Feedback Composite Amplifier) architecture has been completely redesigned on the A90 Discrete with discrete components. The device houses four NFCA-Discrete modules that adopt 39 transistors and are arranged in a fully balanced arrangement. Same as the Original A90, the A90 Discrete features Optimised Voltage Current Hybrid Feedback Architecture along with UHGF(Ultra-High Gain Feedback) design technology. With its fully-discrete design, the A90 Discrete achieves an extremely powerful output rating of up to 9800mW @ 16Ω of load. Topping A90 Discrete is not only about throwing high-output power, it’s about maintaining ultra-low distortion with high power too. It achieves <0.00005% of THD+N ratings at 5800mW of output power(32Ω of load).
Topping A90 features a set of stereo inputs housing RCA and XLR input ports. It can be paired to the Topping EXT90 extender and provide a total of 4 XLR and 2 RCA stereo inputs together. As for headphone outputs, Topping A90 Discrete supports both single-ended as well as balanced headphone connections with three headphone output ports at the front. It has 4-pin XLR and 4.4mm balanced headphone ports and a 6.35mm single-ended headphone output port. A90 Discrete has two-level gain settings allowing the users to pair both sensitive as well as high-power requiring headphones and IEMs with the amplifier.
A90 Discrete can also be used as a pre-amp, feeding signal into a power amp for your stereo chains. It supports both single-ended RCA as well as balanced XLR pre-outs. It also has a ground loop terminator that effectively reduces any noise or interference introduced due to ground loop issues. Topping A90 Discrete is available now on pre-order priced at 599$.
