Product Launch: Topping E50 & A50 Stack!

Topping requires little introduction these days. Their sources frequently top the measurement charts and their reasonable pricing has made them a favourite with both fans and critics. More so, their new models have continued to build upon this foundation, delivering increasingly impressive objective measurements despite keeping the cost just as low. Their latest offerings have focused on expanding the feature set and IO in order to provide not only a high-performance listening experience but a versatile one too. With that, welcome the new E50 and A50 stack that build upon the popular E30 and L30 that were previously released.

E50 DAC Highlights

The E50 uses ESS’ ES9068AS DAC chip, one of their highest performance chips currently available and with native MQA support. Combined with the XMOS XU216, you receive huge codec support up to DSD512 Native and PCM 32-bit/768kHz. The E50 supports RCA and balanced TRS output while also featuring an ultra-low noise preamp and remote control operation in tandem with a bright colour display.

L50 AMP Highlights

The L50 represents a huge spec bump over the L30, now supporting balanced output, 3-gain settings, pas through mode and upgrade all around to sound quality. Using Topping’s famous NFCA module inside, it outputs a whopping 3.5W of power per channel into a 16-ohm load with a <0.3uVrms noise floor rand <0.1 Ohm output impedance. This should make it an excellent choice for both difficult to drive headphones and sensitive IEMs, especially combined with its more diverse gain options.


The E50 is available for $269 USD and the L50 is available for $229 USD on Apos Audio. You can also purchase both in a bundle at a discounted price via Apos Ensemble! Expect a review coming soon to THL!

Product Launch: Topping D30 Pro & A30 Pro

Topping has achieved very frequent recommendation recently with their chart-topping source designs and reasonable pricing. Perhaps more impressively, the company demonstrated that they were able to scale their high-end technologies down to their more affordable models without sacrificing much performance.

The D30 Pro and A30 Pro matching DAC/AMP combo continue their winning streak of products. Both carry the design scheme of the 90-series with a rounded faceplate and larger volume dial. The D30 Pro offers a Quad DAC setup with unconventional 4x CS43198 chips promising fantastic SNR. Meanwhile, the A30 Pro uses Topping’s signature NFCA module alongside balanced input like the A90. It offers a whopping 6W of power output alongside a 0.1ohm output impedance.

The A30 Pro (Apos AudioHiFiGO) retails for $349.99 USD while the D30 Pro (Apos AudioHiFiGO) retails for $399.99 USD at launch. Apos Audio is selling the 30-series through their ensemble program offering additional savings. For $759.99, Apos are able to provide both sources alongside a balanced XLR cable, representing almost $70 USD savings overall.

Product Launch: Topping Pre90 & Ext90!

Following up on their hit amp designs, Topping just announced the Pre90 preamplifier and Ext90 input extender to take their D90/A90 stack to a whole new level.

The Pre90 offers the same NFCA module from the flagship A90 in addition to voltage current hybrid feedback architecture and UHGF technology to provide excellent DC and AC performance. It offers an ultra-low noise floor and extremely high 145dB dynamic range promising zero audible noise and the darkest background.

The Pre90 offers a max gain of 16dB and relay volume control to offer precise volume control, longevity and complete channel balance. In addition, the Pre90 offers a safe volume feature that will kick in when the saved volume of the target input or output exceeds set safe volume and will reduce the output to the safe volume to protect hearing and equipment.

The Ext90 was designed to be used in tandem with the Pre90 and is offered in a bundle. It offers extended inputs, most notably, 2x unbalanced RCA and 4x balanced XLR.

You can read more about the combo and purchase a set for yourself on Apos Audio.

Product Launch: Topping A50s Balanced Headphone Amplifier!

Topping has been hitting it out of the park with their latest releases that piggybacked on their very impressive NFCA amp modules that enable excellent measurable performance. Most impressively perhaps is that the company has transplanted this technology into their affordable offerings; we recently took a look at the entry-level L30 and found it to be one of the most competitive designs on the market in its price point. What it lacked was balanced output, input flexibility and, to some extent, soundstage expansion.

The new A50s look to address this, the successor to the A50 and, as one would expect, an all-around improvement at the same price point. It brings a higher 143dB SNR as opposed to the A50’s 123dB, and THD of just 0.0007% down from 0.004%. Implementing Topping’s renowned NFCA amp modules as seen on the flagship A90 and more recent L30, the A50s offers 3.5W x2 into a 32-ohm load, leaving plenty of headroom for high-impedance headphones.

In addition, it offers the same 0.1-ohm impedance and < 0.3uVrms noise floor of the L30, promising a black background and linear signature on even the most sensitive low-impedance multi-driver earphones. The A50s is also a balanced design with 4.4mm output in addition to a traditional 1/4″ single-ended output. It doesn’t support XLR in any manifestation, however.

The A50s is shaping up to be another promising offering from the company and will be available soon at $199 USD from Apos Audio. As always, look forward to a full in-depth review on THL soon!
