Topping Mini 300 Amplifier Review

[Roland68]

Hi, I already bought the E50 II and the PA5 II with balanced cables. Am I missing out on much with this new Mini 300?

You're not missing anything, except that Topping has managed to offer comparable performance and measurements in a less expensive device.
The Topping PA 5 II uses a few higher-quality and more expensive components, but these don't result in a longer lifespan or audibly better measurements.

thanks for the reply!

I would argue that you're not missing out on anything audible.

You paid $80 more for 1 dB less noise.

I think they mean a trigger from the E50 to turn on the mini-300. And I agree that it should have that feature.

That's correct

Specs:

• 【Professional Balanced Class-D Design】Featuring a fully balanced amplification architecture, the TOPPING Mini300 minimizes noise and interference for a pure, distortion-free signal path—achieving professional-grade transparency and depth in a compact form.
• 【High Power Output with Ultra-Low Distortion】Delivering up to 140W×2 @4Ω (THD+N <10%) and maintaining <0.0004% THD+N @8Ω 5W, Mini300 combines high fidelity and high power, ideal for both HiFi listening and studio monitoring applications.
• 【Exceptional Dynamic Range and Clarity】With 124dB DNR and 124dB SNR, Mini300 preserves every subtle musical detail—allowing instruments and vocals to sound natural, lifelike, and richly layered.
• 【Auto Power Sync with TRIG Control】The TRIG-linked power function automatically powers the amplifier on/off in sync with connected devices—making system control effortless and eliminating the need to operate multiple units individually.
• 【Dual Input Compatibility】Supports both balanced TRS and unbalanced RCA inputs—no adapter required. Easily integrates with DACs, preamps, or audio interfaces for flexible system setups.
• 【Quiet, Safe, and Reliable Operation】Engineered for silent startup/shutdown, and equipped with overheat and overcurrent protection, ensuring long-term reliability and zero noise during playback.
• 【Compact and Durable Aluminum Design】Built with a CNC-machined all-aluminum chassis available in multiple finishes. Bottom and side cooling vents improve thermal efficiency while maintaining a clean, modern appearance for any desktop setup.

Things to try with this:
1. Run balanced, but use - for hot and reverse the speaker cables. The reason is that many cheap opamps have poorer PNP transistors than NPN. Going in backwards (And fixing it on the outputs) uses the NPN transistors. Made a HUGE difference with my Hypex 122 amp because it's input chip is a 5532.
Next, try running two of these in dual mono with shorting TRS plugs on the two unused inputs. I plan to try this as soon as my second amp arrives.

That won't work with the Mini 300; you'd have to modify the inputs and outputs.
The TPA3251 in the Mini 300 is already configured for BTL; for mono, you'd have to change the circuit to PBTL. It's best to take a look at the datasheet.

Even if they painstakingly convert the Mini 300 to mono operation, they won't increase the output power (it's already configured for BTL), but will only make it 2-ohm capable, even though it's not very sensitive to that anyway.

However, a 3E Audio A5 with 2 x TPA3251 in dual mono PBTL operation would be the better choice and roughly the same price.

Any idea what cost effective Spotify Connect Receiver with 3.5mm output could be used with the Topping Mini 300 besides the Wiim Mini which I am aware of.

Why would you require the output to be a 3.5 mm socket? And what's wrong with the WiiM Mini? Are you looking for something even cheaper?

RCA output would be fine. Jut wondering if there is a cost effective transport with a nice DAC and Spotify Connect.

the dx1 ii came yesterday , the cable today and the mini 300 tracking shows it'll be here in a few days . the dx1 ii is smaller than i thought it would be , just a observation not a complaint . gonna use them with a pair of klipsch rp500mii on my desk . got the amp purely on the ratings here in this review and the price . the dx1 ii gets a lot of youtube love and good comments here . i'm looking forward to playing with it's topping tune software
thanks to Amirm and all who commented here

Nice setup!

For the Klipsch, I'd highly recommend you program the following PEQ preset into your DX1 II:

Spoiler: Preset

Preamp: -2.7 dB

Filter  1: ON PK Fc    52 Hz Gain +2.93 dB Q 0.92
Filter  2: ON PK Fc   102 Hz Gain -1.71 dB Q 1.47
Filter  3: ON PK Fc   356 Hz Gain +2.12 dB Q 0.98
Filter  4: ON PK Fc   820 Hz Gain -1.50 dB Q 3.00
Filter  5: ON PK Fc  1760 Hz Gain -1.55 dB Q 2.83
Filter  6: ON PK Fc  4194 Hz Gain -1.19 dB Q 0.99
Filter  7: ON PK Fc 13186 Hz Gain -3.25 dB Q 1.13

It will correct the stock treble tilt of the Klipsch:


(dotted: stock, solid: corrected)

thanks staticV3 .
i'm 64 and don't hear sparkly highs like i used to , but Erins youtube review did influence my decision to get these .

Cool, don't be afraid to leave an audiophile review lol. I enjoy subjective impressions. I boxed up my Bryston B60 with how it performs. I feel like it's coming from the same place of 'neutral' as the Bryston, yet the improvements in sound were hard to ignore.

Good luck finding a replacement for that oddball 38V power brick with the GX12 connector when it goes poof.

Not an issue now nor will it be later.

The connector in your first link is the wrong one; a 2-pin connector is required, not a 3-pin one.
