In a nutshell, ships within 24/48 hours basically means that your product will be shipped out or dispatched from our warehouse within 24/48 hours after placing the order. It also indicates that the products are readily available at our warehouse and once we receive your order, we dispatch it out at the earliest either on the same day or the next working day depending on when you’ve placed your order.


What it does not mean:

A lot of our customers assume that it means their order will get delivered to them within 24/48 hours, but that’s not what it means. For an order to reach you, it can take anywhere up to 3-4 business days, depending on which part of India you are placing an order from.

A Follow-Up To The Widely Popular A90, Topping Introduces A Fully Balanced Headphone Amplifier A90 Discrete

Topping is known to make the quietest and most linear power amplifiers. The design engineers at Topping develop the amplifiers with precision delivering out-of-the-box audio performance. The concept and products of Topping have won the recognition of audiophiles worldwide. Since Topping first unveiled the A90 in 2020, audiophiles went berserk. The A90 Discrete is no different from the great products that Topping consistently offers with comprehensive, high-performance features. The Topping A90 Discrete is a fully balanced headphone amplifier that can also act as a pre-amplifier. The design overhaul on the A90 Discrete compliments the output power handling capacity. You will be able to drive high impedance and low sensitivity headphones/IEMs with ease. The differences over the classic A90 are that the A90D incorporates the Discrete Nested Feedback Composite Amplifier with a THD+N of <0.000055% as compared to <0.00006% on the classic A90. The Topping A90 Discrete also has higher output power ratings and an R2R relay volume control that reduces channel imbalance delivering optimum performance.

Discrete NFCA Modules & Hybrid Feedback Architecture With UHGF For Unmatched Clarity

The A90 Discrete introduces a completely overhauled design, implementing fully discrete NFCA (Nested Feedback Composite Amplifier) modules. Each module uses 39 transistors, enabling excellent DC and AC performance. This approach enhances dynamic range and transparency, delivering pure, clean, and natural audio. Topping has improved the Voltage-Current Hybrid Feedback architecture, pairing it with UHGF (Ultra High Gain Feedback) technology. The result is an amplifier with ultra-low distortion, exceptional control, and the ability to drive even the most power-hungry headphones with authority.

Features Ground Loop Noise Terminator Switch (GLNTS) & Provides Ultra-Low Noise

To address hum or buzz caused by ground loops in complex setups, Topping includes a GND/LIFT switch. Simply toggle to LIFT to eliminate unwanted ground loop noise when multiple devices are connected to the same power source. With a noise floor as low as 0.2uVrms, the A90 Discrete is well-suited for even the most sensitive in-ear monitors. Its two-step gain switch ensures the right amount of power without hiss or noise, regardless of the connected headphones.

Precision-Matched Transistors For A Silent Background With 12V Trigger For Seamless Integration

The use of ultra-low noise, precision-matched transistors ensures that the amplifier maintains an incredibly silent background. This contributes to a pitch-black noise floor and enables you to hear fine details in your music like never before. Equipped with a 12V Trigger interface, the A90 Discrete can be synchronised with other gear. You can turn multiple devices on/off together using just a 3.5mm to 3.5mm cable, simplifying power management in complex setups.

High Output Power With Flexible Input Options & EXT90 Support

Thanks to its revamped internal design, the A90 Discrete can comfortably drive high-impedance headphones and sensitive IEMs alike. Its high output current and low impedance ensure minimal distortion and maximum control, even with demanding gear. Out of the box, the A90 Discrete includes 1 x XLR and 1 x RCA stereo input. When paired with the Topping EXT90, this expands to a total of 4 x XLR and 2 x RCA inputs, allowing you to build a full-featured desktop audio system with multiple sources.

Experience Accurate & Dynamic Sound Signature

Sound from the A90 Discrete is described as natural and uncoloured, with crisp bass, a smooth top-end, and a transparent midrange. It faithfully reproduces the character of a recording without adding coloration — ideal for analytical listening or mastering work.

Store Your Audio Settings With Memory Presets and User Profiles & R2R Relay Volume Control

You can store and recall two user-defined profiles (C1 and C2) that remember your current settings, including volume, input, output, and brightness. Perfect for quickly switching between headphone and speaker use or different listening preferences. Unlike standard potentiometers, the A90 Discrete uses a relay-based R2R volume control system. This offers superior channel matching, longer life, and eliminates low-volume imbalance — a common problem with sensitive IEMs.

Dual Functionality: Amplifier + Preamp With Simultaneous Output Options

The A90 Discrete isn’t just a headphone amplifier — it doubles as a high-quality preamplifier. With output impedance at 20Ω (SE) and 40Ω (balanced), it pairs effortlessly with various power amps, making it a versatile centre piece for any system. You can switch between headphone amp, preamp, or both simultaneously. This flexibility means you can run multiple output configurations without unplugging anything — convenient for desktop and studio setups.

Seamless Connectivity With Versatile Audio Input and Output Support

Connectivity is a strong point of the A90 Discrete. It includes a wide range of headphone output options to suit most cables and terminations: a 4-pin XLR balanced output, a 4.4mm balanced output, and a 6.35mm single-ended output.On the rear panel, you'll find balanced XLR inputs, single-ended RCA inputs, as well as balanced XLR and RCA preamp outputs. This variety ensures seamless integration into virtually any audio setup, whether you're using it purely as a headphone amp or as part of a larger system with external sources or power amplifiers.

Exquisitely Designed For Impeccable Aesthetics & Essential Accessories Included

Topping has long been recognized for merging sleek aesthetics with top-tier build quality, and the A90 Discrete is no exception. The design exudes a premium feel, with a solid chassis and elegant finish that will complement any desktop setup. Out of the box, the A90 Discrete comes ready to go. Included are a remote control, a 6.35mm to 3.5mm headphone adapter, an AC power cable, a warranty card, and a user manual. These accessories ensure you can set up and enjoy the amplifier immediately, regardless of your headphone plug type.

Comes With Full-Featured Remote Control For Easy Access To Features

Included is a comprehensive remote control that handles standby, input/output switching, gain control, volume, mute, and brightness adjustments. It even lets you store custom volume levels for each mode, ensuring smooth and safe listening transitions. (add if necessary)
