SUPER-CLEAN POWER FOR YOUR HEADPHONES WITH A HIGH-PERFORMANCE NFCA AUDIO CIRCUIT
The Topping A30 Pro is embedded with the redesigned NFCA (Nested Feedback Composite
Amplifier) based audio circuit. This circuit is optimised for stellar performance with super-clean and crisp
output. The A30 Pro is equipped with 10xOPA1656 OP-Amp architecture and UHGF(Ultra High Gain Feedback)
technology to maximise the performance of the A30 Pro. The overall Total Harmonic Distortion + Noise (THD+N)
of the Topping A30 Pro is below 0.00006%. In other words, the Topping A30 Pro restores up to 99.99994%
original sound so you can enjoy your music at pristine quality.
CAPABLE OF DRIVING THE MOST POWER-HUNGRY HEADPHONES WHILE RETAINING THE DYNAMIC RANGE
Topping A30 Pro is an incredibly powerful headphone amplifier. It can power hard-to-drive headphones without any trouble. It outputs up to 6W at 16 ohms of load, 5.5W at 32 ohms, 840mW at 300 ohms, and 420mW at 600 ohms of the output load. Massie output power and margin bring excellent control ability and drive all the demanding headphones with ease. It supports both power-hungry headphones and sensitive IEMs while maintaining a clean audio signal. Thanks to its NFCA-based circuit and UHGF (ultra high gain feedback) technology, the A30 Pro delivers a stunning 145dB of dynamic range. This means that 145dB exists between the lowest and highest volumes of sound it can reproduce, resulting in exceptionally realistic playback.
CLASS-A OPERATION FOR HIGH IMPEDANCE HEADPHONE AND GROUND LOOP ELIMINATING TECHNOLOGY
When the Topping A30 Pro is paired to a headphone with an impedance greater than 250 ohms, it offers complete Class A operation, thanks to the ample quiescent current architecture. When multiple pieces of equipment are operating in conjunction, ground loop noise can occur. Ground loop noise most often manifests as a buzzing or humming sound, which is loud enough to damage speakers or headphones. The Topping A30 Pro solves this issue with a dedicated GND/LIFT switch on the rear panel. When in normal use, set the switch to GND. If you encounter ground loop noise, flick it to LIFT, which will change the ground point of the A30 Pro from its chassis to the equipment it’s connected to, eliminating the noise.
OFFERS A VARIETY OF CONNECTIVITY OPTIONS WITH THREE-STEP GAIN AND INPUT PASSTHROUGH
The Topping A30 Pro is designed to be compatible with various headphones and to enable this, it features 4-Pin XLR + 4.4mm and 6.35mm outputs. You also get RCA and XLR connections for the input stage. The inclusion of these outports allows you to connect virtually any headphone without compromising on functionality or quality. The Topping A30 Pro headphone amp provides Three-Step gain settings with -14dB, 0dB, and +14dB gain modes to switch for use with IEMs or high impedance and full-size over-ears. Just connect your headphones or IEM and leave the rest to the Topping A30 Pro desktop headphone amp. When powered down, the A30 Pro passes the input signal directly to RCA or TRS connections without applying amplification. This allows you to connect active monitors to the A30 Pro and benefit from an outboard DAC with pre-amp functionality without introducing another amp into the chain. This process is called Input Passthrough and elevates the functionality of the Topping A30 Pro tenfolds.
BEST PAIRED WITH THE TOPPING D30 PRO DAC FOR EXCEPTIONAL PERFORMANCE AND CLEAN AUDIO
If you're looking to add a high-quality DAC to your desktop setup with the A30 Pro, do consider the Topping D30 Pro. The Topping A30 Pro and D30 Pro share the exact spatial dimensions, making them easily stackable. At a combined 4” of height, they're modest enough to fit under a monitor, in a desk compartment, or on a space-restricted shelf. The D30 Pro offers an extremely low level of jitters for all kinds of inputs and allows you to utilise the input passthrough capability of the A30 Pro. The pair of Topping A30 Pro and D30 Pro is an excellent choice for the modern music lover looking for a setup that can do it all.

"I like both the pure clean sound of op-amps,the mild distortion of tubes too.Tubes amps are my favorite but I like to alternate back & forth with tubes & the op amp units."

I think there are very few amps out there in this price range that can compete with A30 pro's astounding power output. It's not only powerful, it sounds very, very clean and neutral. Compared to my Aune X1s Pro's amp section, A30 pro sounds a bit more balanced with my beyerdynamic DT880 pro 250 ohm headphones and the treble of my cans sounds much more rounded. It's clean, powerful and has small form factor. It gives my headphones a very good headroom in terms of clean distortion free volume.
Things to note -
1. A30 pro runs a bit hotter than my Aune, not a huge deal, but that's why it has so many ventilation holes on it.
2. The supplied power cable is of Schuko type, so it is unusable in indian sockets. I had to buy a separate 3 pin cable for this amp.

Hey Rupam, We are happy to hear the positive feedback about this amplifier. Thanks for taking time and sharing it with us. Its good to see that you're loving the sound output after using it with your setup.
Im using this for my Sundara (single ended). Using high gain really improves the dynamic range and separation of sundara (even though mid gain was loud enough).
Connected this to Zen DAC using RCA. Heard using balanced input improves the signal, hence improving output as well, waiting to get an balanced interconnect and try that out as well.
Sound stage is actually little smaller than zen dac's inbuilt amp (with ifi power supply), but noise/distortion and dynamic range are good improvements.
Sound signature is very clean, neutral-warm (not neutral-clinical). Very impactful sound signature.
I guess sound stage and impactful sound are more or less inversely proportional. If one should increase, the other should decrease.
If it had some more sound stage, it would be perfect for me. Hope balanced input and balanced connectors for headphone helps in that.
Other headphones used: DT 770 pro 80ohm, HD599 both sounded better with this. (Even though zen dac is very loud for HD599, this amp still made HD599 much better)
P.S. Make sure to push RCA plugs til the end or else sound quality degrades audibly. Also, sound quality improves after running for about an hour - that's when it reaches its max performance (more impactful, more power, more real)
BTW, the 1/4" adaptor provided with topping has different sound signature than identically looking sundara's 1/4" adaptor to a shockingly audible amount. I feel topping one sounds greater in quality.
But beware I have tweaked my pc for audio at hardware and software/os level (yes that matters) and have tended the best I could to electrical sources (pc, monitor, modem sharing same ground, trying reverse polarity etc.). So, if you haven't done that, the audible difference might be less.
But at this price point, I think everyone should start tweaking to truly listen to its dynamic range.
HI Prasanth,
Wow! that was one hell of a detailed review on the A30 Pro. Well we hope you are loving your purchase & thanks for the note. Keep the music playing buddy!
Overall build quality is great, could have provided basic RCA or XLR cables out of box to help listening to music right away.Had to buy the balanced XLR cable seperately. Interface and settings could have been more user friendly. Never owned an amp before so couldn't compare, but overall experience is quite good...the clarity, clean audio, bass is there but not overwhelming.
Coming to headphone zone, very quick delivery packing was adequate received updates at every stage of shipping...very happy and satisfied :)
HI Vinod,
We thank you for this lovely review & we are glad you are enjoying it! Keep the music playing.
Thanks to Headphonezone for shipping it in less than 24 hours, that's too fast!!!!
Headphone I paired with this are LCD 2 Classic and HD6XX. You need to have a clean source to bring the best of this AMP. It brought the best out of LCD2C with the dynamics and slam I never heard out of any headphones, the bass is tight and hits harder. HD6XX also sounded great with this but on RCA input the power is very low and I was almost reaching maximum volume on quieter recordings.
It's one best AMPs with clean power for any headphone. It can easily power any headphone but you need balanced XLR input to unleash its full potential. With RCA input the power is subpar.
I was afraid it will sound dry and clinical but to my surprise it sounded a touch warm and musical. You can't find a better AMP than this at this price point.
Topping just got another winner.
Works as expected
Thank you for the great review & ratings Sanidhya!
Very nice product 🤩
My arya V2 sounds perfect with this AMP on High gain using only below 1oclock volume knob for recent recording, for older recording above 1oclock is must to bring all dynamic and transient without clipping.
It gets very hot that external fan is required in summer season to keep the amp from thermal bottleneck.
