Review: Super power! - The power is undeniably impressive. This amp drives all my headphones effortlessly, making it the cheapest beast I’ve come across. The sound is slightly less refined compared to the 9-series, but at this price, the performance is already a steal. Absolutely love it!
Review: As Good as it Gets - Probably the very best headphone amplifier out there. I've had it for nearly two years, and it's been trouble free. Unbelievable power, will drive virtually any headphone, completely transparent and distortion free, and has a really cool set of features including some great options for VU meters in its electronic display. Was only $400, so an absolute steal. Don't know why anyone would want anything else. It has my highest recommendation. It is literally as good as it get.

## Features

- 👍 T'ang-ku-la Module ▶️The T'ang-ku-la Module uses a new three-stage feedback circuit. Further reducing noise and high frequency distortion, making the dynamic range rise to an unmatched 147dB new realm. The new technology greatly reduces heat generation, thus greatly improving reliability, extending electronic component life, and reducing thermal noise.
- 👍 Ground Loop Noise Disappearing magic ▶️ When multiple devices are used in combination, ground loop noise may be encountered. A70 Pro adds a GND/LIFT switch, when ground loop noise is encountered switch to LIFT and the noise will disappear.
- 👍 Relay volume control ▶️ A70 Pro uses relays and resistor networks to form R2R volume control module, which provides precise volume control, long service life, and will not deviate even at low volume.
- 👍 A Headphone Amp, also a Preamp ▶️ The A70 Pro drives headphones well, and it can also be used as a preamp. It has the same high performance as the headphone amp mode, with an RCA output impedance of only 50Ω and an XLR output impedance of only 100Ω, allowing it to be used with a wide range of input impedance for various power amplifiers. In addition, a full-featured remote control makes operation even easier.
- 👍 Expandable inputs ▶️ The A70 Pro has one set of balanced XLR and one set of single-ended RCA inputs. But with the Ext90 input expansion, you get a total of four balanced XLR and two single-ended RCA inputs.

### ⭐⭐⭐⭐⭐ As Good as it Gets

### ⭐⭐⭐⭐ Versatile
*by A***R on October 7, 2024*

I bought this and the topping A90 D. I compared the tw. I found no real great difference in the audio. but the overall versatility of the topping A7-0 pro made the choice a no brainer. just the ability to set a volume safety so you do not blow up your headphones makes this a clear choice. I am using it as a headphone amp only. So I can not say anything about the pre-amp capabilities of this unit. Like the remote control as well.
