The ultra-low noise floor of  less than 0.3uVrms is miles ahead of its competition and makes the Topping Pre90 the Pre-amp one might need in its audio chain. The device boasts a high dynamic range of up to 145dB, ensuring excellent performance with a super clean dark background.

One Pre-Amp For All Your Sources:-

The Pre90 features a fully balanced structure that can handle both balanced and single-ended signals. On itself, the Pre90 features one single-ended RCA input and one balanced XLR input, but with the help of Ext90, it can be connected to 2xRCA single-ended and up to 4xXLR balanced inputs. So it can be connected with multiple sources and active input can be selected easily via the included remote control. For output, the Pre-90 features fully balanced XLR and single-ended RCA output. You can also output from both the ports simultaneously to connect to two amplifier systems at once.
