Very lightly used Topping A90 Discre Headphone Amplifier (less than 100 hours) like new condition. This is an extremely powerful and neutral amp, it sounds amazing.

Hallo, ich biete hier mein MIFA A90 wie abgebildet zum Verkauf. Die befindet sich in einem sehr guten bis neuwertigen Zustand und funktioniert einwandfrei. - IPX7 wasserdicht - robustes Gehuse - 30 Stunden Spielzeit - 60W BoomBox (mehrere Treiber, mit Bass) - mit seitlicher RGB Beleuchtung (einstellbar und abschaltbar) - Bluetooth - AUX-In (3,5mm) - MicroSD - USB-C - USB - 25 x 10,6 x 11,5 cm - mit USB-C Kabel - mit Tasche - Anleitung - OVP Privatverkauf (ich schliee jede Sachmangelhaftung aus...)

Featured here is a Topping A90 that I’ve had and used for a few years. It can easily drive all sorts of equipment but I’m selling it now because time just isn’t a thing I have anymore. Despite the time passing, the device works perfectly and it looks to be in pretty solid condition. This particular unit only has a couple of scuffs and scratches, mainly along the edges and face. Additionally, one of the little rubber feet came off during one of the moves we had, but a new one in theory could be ordered and stuck on where the old one fell off. Please see the photos for details. This does not affect the unit in any other functional way, besides maybe being a little wobbly at times. If you’re okay with that this is a great little unit for sure! This device also comes with a power cord but I no longer have the box after so many years. Thank you for looking and reading!

Lightly used.The product shown in the photo will be shipped as is.It works properly.Please check the cosmetic condition in the photos. ?Fully discrete NFCA also create wonderful amp? TOPPING A90D uses fully discrete components to redesign the NFCA (Nested Feedback Composite Amplifier)module. 4 built-in NFCA-Discrete modules which each them uses 39 transistors build up fully balanced structure. The optimized Voltage Current hybrid feedback architecture along with UHGF (Ultra High Gain Feedback) technology provide excellent DC and AC performance.?High output voltage, high current, low output impedance, no headphones that cant be dealt with?High output voltage can easily drive high impedance headphones; High output current allows low-sensitivity headphones to obtain enough power; The low output impedance will not bring unnecessary effect on FR when driving low-impedance headphones. Different headphones can be easily driven by the A90 Discrete.?2 Gain settings? TOPPING A90 Discrete has two gain options, which are enough to cover a wide variety of headphones: low gain to drive the IEMs with high sensitivity, and high gain to drive full-sized over-ears. Combined with the 0.2uVrms ultra-low noise, even sensitive lEMs will not suffer from any noise.?Ground Loop Noise Terminator? Ground loop noise may be encountered when multiple devices are used in combination. A90 Discrete adds a GND/LIFT switch to solve this problem. When in normal use, set it to GND; and when ground loop noise is encountered, switch it to LIFT. Then the ground loop noise is eliminated.?A Headphone Amp, also a Preamp? When it is in preamp mode, you can get the same high performance as the headphone amp mode, and the 20ohm SE and 40ohm balanced output impedance are widely suitable for various power amplifiers. A90 Discrete can not only switch between the headphone amp (only output from the headphone jack) and the preamp(only output from RCA and XLR), but also support the output from all at the same time.

The units are in excellent condition. This topping a90 discrete is a great addition to your home audio system. It comes with an ext90 and a connecting cable to make sure you have a seamless audio experience. Whether youre a music lover or a gamer, this topperforming product will not disappoint. It has a sleek design and is easy to use, making it a perfect fit for anyone. With its high-quality sound and durable build, this topping a90 discrete is sure to impress.

This desktop audio amplifier has 2 channels and 4 inputs, allowing you to easily switch between different devices. With multiple outputs, you can connect multiple headphones.

Get the most out of your audio experience with the Topping A90 Headphone Amplifier. “Mr. Clean.” “The Giant Killer.” “The Best Amp Ever.” These are a few of nicknames the TOPPING A90, our best-selling amplifier, has gained since its release. At its most basic level, it’s a balanced amp and pre-amp with tremendously clean and powerful output. At its broadest level, it’s become the benchmark by which all other solid state amplifiers below $1,000 are judged. Calling all cansPlanar magnetic, electrostatic, dynamic drivers, IEMs–pick your poison, the A90 can handle it. Thanks to its NFCA modules, three-step gain switch, and excellent AC and DC performance, the A90 can push loads of power into high-impedance full-sized headphones or pare that power back in order to drive sensitive IEMs. And with an ultra-low noise rating and high dynamic range, the A90 does it all without producing any audible noise. Pre-amp modeWith the A90 in pre-amp mode, connect a power amplifier to drive bookshelf, desktop, or floor speakers. You can also connect the A90 to the D90SE DAC in pre-amp mode to create a complete high-end sound system.
