Topping A90 Discrete Headphone Amplifier 4-Pin-XLR 4.4 Balanced NFCA Fully Discrete Balanced Amp 9800mWx2 Output Power 2 Gain Settings Black

Product description

• Fully Discrete NFCA Module - 4 built-in NFCA discrete modules which each of them uses 39 transistors to build up a fully balanced structure. A90 Discrete does not only provide excellent DC and ultra low distortion, but also own stronger output capability which allows the amp driving low impedance headphones even more effortlessly.
• 2 Gain Settings - The A90 Discrete has two gain options that low gain drives the IEMs with high sensitivity and high gain drives full-sized over-ears. Combined with the 0.2uVrms ultra-low noise, even sensitive lEMs will not suffer from any noise.
• 4 x XLR and 2 x RCA Stereo Inputs - The A90 Discrete provides you 1 x XLR and 1 x RCA stereo inputs, but when working with an Ext90, they could provide totally 4 x XLR and 2 x RCA stereo inputs.
• Headphone Amp & Preamp - When A90 discrete 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. When used as a headphone amplifier, it can be used with the D90SE D9OLE DAC. When used as a preamp, it can be used with LA90, which provides more precise volume control, remote control and additional input.
