Im selling my Topping A90 in excellent condition with minor scuffs on one side per pics. Feel free to reach out with any questions you may have, and thank you for checking out my listing.

Topping Dx3 Pro+ in like new condition. It comes with original box, power adapter, bluetooth antenna, and remote control

This is a gently used Topping Pre90/Ext 90 for sale offered at a very reasonable price and works flawlessly! I am selling both the Pre90 and EXT90 together as a whole and both are in excellent operating condition. I refer to the Stereophile review of the Topping Pre90 from the Jan 28.2022 edition and was determined to be superior to the Schiit Freya Plus. I refer you to the Topping or Apos Audio website for its amazing specifications. It is a super clean , flawlessly working preamplifier and I am selling the Pre90 + EXT90 together as a single sale with the remote and I have kindly included a Sofabaton remote which throws a much wider , accurate IR signal to the Topping Pre90 as the factory remote requires carefully aiming towards the IR sensor of the Pre90 and the Sofabaton universal remote throws a much wider signal which allows for more effortless volume adjustment. This preamp works perfectly, the Pre90 and the included Ext9p are both meticulously packed in the cushioned factory boxes in a single shipping box, will be promptly sent to you upon receipt of payment. I maintain 100% review rating since 2005 and this preamp works amazingly!

Audio Review raves about this DAC. For the price, its understandable. It operates as it should and is in good shape. I have included a longer usb power cable and the usb computer input cable. I comes with a very simple to understand remote which is probably a good thing since I dont read Chinese and havent a magnifying glass available.

Topping A90 Balanced Headphone Amplifier Pre-Amplifier - Barely Used about 1 year sparingly. Comes with power cable and thats it.It is in mint condition no scratches and you can see plastic caps not even removed from the back. Dont mind on the front there was a tiny piece of bubble wrap got stuck to the switch it doesnt help and removed...LOL So SirExperience high-quality sound with the Topping A90 Headphone Amplifier. 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. This Topping A90 is a reliable amplifier that comes brand new in its original box. It is suitable for home audio systems, TVs, and other consumer electronics. 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.

Condition is used in perfect condition w/original box, cables, and remote. No issues, operates as new. About this item ?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.
