Topping A30

    • Full aluminum shell
    • 0dB/9dB/18dB gain swich
    • 3.5mm&6.35mm headphone output
    • Output power :1540Mw*2 @32ohm
    • Output power : 290mW*2@300ohm
    In order to fit all kinds of headphone, we designed A30 to have 2 working mode(Hi or Lo working voltage), 3 gain set(0dB, 9dB and 18dB) and 2 heaphone output with different impedance.

    Most competing products use 1x15V or etc adapter to the amplifier, this 1x15V will be convert inside the amplifier and cause noise and interference.
    But we use linear power adapter to provide 2x15V and 1x8V to A30, which help A30 avoid these problem. 2x15V used for high fidelity headphone amplifier circuit. 1x8V used for MCU, LED and relay. Less noise, less interference.

    Powerhouse on a budget

    Pros - Powerful, neutral
    Cons - lacking soundstage width and depth
    Firstly I would like to thank Topping for sending me these samples for review, as always I will try to write an honest review. Both units have had over 50hrs of burn-in.

    Gear Used:
    HP Laptop / Dell Desktop > D30 via USB > A30 > German Maestro GMP 8.35d / Hifiman RE2000 and many others.


    Tech Specs:

    Packaging, Build Quality and Accessories:
    The units both come in a very sleek white box, with a very simple outline drawing of the unit on the front of the box, and the model number on the opening flap. Open up the box and you are greeted with the units held firmly in place in foam. The packaging is simple but effective and protects the units well during shipping.

    The build quality on both units is very good, I think they look great in the brushed metal finish. The volume knob on the A30 is very smooth, all switches feel sturdy and like they will last, and all sockets are tight and have little to no play. All the sockets on the back are in good places and not too close together. Overall they are very well made for the price, and the all metal casings will no doubt help prevent interference from nearby devices. The power indicator on the D30 is a small blue LED, on the A30 the ring around the volume knob illuminates blue, I like this design.

    The A30 only comes with a power supply, the D30 comes with a power supply and USB cable, no frills or unnecessary bits and bobs, this no doubt helps keep the price down. Although I think if they are purchased together a short 20cm set of RCA interconnects would be a nice added accessory.

    Ease of Use and Features:
    The A30
    has a few great features, it has RCA input, and also RCA output which is a direct pass through. This does mean it cannot be used as a pre-amp though, and they output can be configured so it is either outputting at the same time as the headphone out, or it can be made so it gets muted when you plug headphones in.

    The A30 has 3 gain settings, 0/9/18dB, High and Low power modes, and 3.5mm + 6.3mm headphone outputs. It works with most headphones on the market, from sensitive IEM’s to hard to drive full size headphones (doesn’t quite drive the Hifiman HE-6 / Susvara).



    The A30 again is pretty incredible for the price, it uses good components inside and the op-amps are in sockets so you can change them easily. What impressed me is the power the A30 has, it will drive most headphones out there, I got good volume out of the Hifiman Susvara but it slightly lacked body, that is high praise right there.

    I have been using it with IEM’s and full size headphones alike, the noise floor is silent, the gain settings are perfect and the volume knob is super smooth.
    The sound is fairly neutral, the soundstage is quite intimate but overall it is detailed and a very clean sounding amp, nothing stands out which in my opinion is a good thing.

    Now I did change out the op-amp after listening for quite a while stock, I changed them to the Burson V5i Dual op-amps and I think op-amps make a small difference but this was actually quite a big difference. The soundstage widened and got deeper, making the sound more immersive, the bass response got more tactile and ever so slightly fuller, and there was more air to the whole presentation. In my opinion if you get the A30, I highly recommend the Burson V5i Dual op-amps to go with it; it makes this amp a real steal for less than $200.


    Conclusion: Topping are a brand you should look for if you are on a tight budget, both the D30 and A30 punch above their weight stock, and the A30 can be improved by a large margin just by changing out the op-amps. The stack is both visually pleasing, and great sounding, it is a powerful desktop combo that has a neutral and balanced sound, excellent detail and all for under $300. I am quite a fan of these now.

    Sound Perfection Rating:
    A30 – 7.5/10
    (Clean, detailed, powerful, stock op-amp holds it back)

      @Bhargu I would give it a 9/10 with the V5i.

      The V5 and V6 won't fit as standard, you'd need to lay them flat with the op-amp extenders that burson sell.

      Thanks for the reply. I expected the full discrete models won't fit. Still, from 7.5 rated at $110 to 9 rated at $180. Not too bad considering the power output. How well will this compare against Magni 3? Any ideas?

      How would you say this compares to the Magni 3? Also how easy is it to swap out the op-amps?
