A three-step gain switch adapts the A30 Pro to the huge sensitivity gap between IEMs and full-size headphones. From -14dB on the low setting to +14dB on the high setting, the function spans an impressive 28dB. Made to pair with the D30 Pro Desktop DAC The Topping A30Pro is a satisfactory mid-range headphone amplifier with top specification, better sound, and a refined build.

Second, read the following review of the A30 Pro if you have not already done so or watch the video: When Topping created their own NFCA modules, they wanted the maximum amount of power, the highest signal-to-noise-ratio and of course the lowest levels of noise at reasonable prices. A30 PRO maybe uses different op-amps, but it still has the same working principle and some of the lowest noise floor of the industry. With a measured noise of 0.7 uV on its low and mid-gain, up to 1.1 uV on its high-gain, A30 PRO has indeed one of the lowest noise floors recorded on headphone amplifiers. This is world-class performance and I’m putting it in the same boat with Topping A90, Sparkos Labs Aries and Benchmark HPA4. Is this a new amp? Indeed there really doesn't seem to be much info about it, I just learned about 'Topping' recently and am thinking about getting an A30, from the specs & price, looks interesting; http://www.head-fi.org/t/843011/best-cheap-upgrade-from-aune-t1-schiit-magni-1-for-hifiman-400i-topping-d3-or-a30
These qualities initially drew me to Magnius’ more energetic character. However, the A30 Pro’s more measured approach in the low end and the more subtle euphonic character made for a more natural and coherent presentation. The treble on the A30 Pro is also notably more forward while staying safely away from being harsh. For TOTALLY UNRATIONAL REASONS, I tend to prefer DAC's with AK44xx chips. But if Cirrus has been chosen, I assume JohnYang1997 has good reasons for this choice. While both amplifiers have similar input/output ports, the A30 Pro’s output ports are just bypass ports. Meaning the outputs are just shorted to the input signal if the amplifier is turned off, so the A30 Pro doesn’t have any pre-amp output capabilities.

This allows you to connect active monitors to the A30 Pro and get the benefits of an outboard DAC without introducing another amp into the chain.

Layering within the soundstage is also more compressed on the A30 Pro, while also having an overall more forward presentation. The dynamic range on the other hand is not as wide as I expected, as the A30 Pro plays louder than it should in most passages. This is a review of the A30 Pro & D30 Pro together, separated only by the specs and technical bits. I thank Apos audio for sending the duo, they really are a fabulous pair. On the front fascia, the XA-10 has a neater overall arrangement, only having the red volume ring, the LCD screen, and the headphone outputs while having the rest of the controls on the side of the device. With the controls on the side of the device, it proves to be less intuitive than having classic toggle switches. The rear of both devices is similar, where there are inputs for RCA and a pair of 3-pin XLRs. However, the A30 Pro has a pair of pass-through outputs, for both RCA and a pair of balanced ¼” outputs. Also notable is that the A30 Pro has a ground/lift switch at the rear, while the SH-9 doesn’t have an option for eliminating ground loops.Living in Glasgow, Scotland but born and raised near Milan, Italy, I got the passion for music listening as a legacy from my father and my grandfather. However, the similarities end with the general tonality and timbre of both amplifiers. The layers within the soundstage are a bit more spaced out on the A30 Pro, giving it a more open feeling. Images are also clearer and more chiseled with the A30 Pro, giving a better sense of directionality within the soundscape.

One thing to note about the Magnius though is that the outputs on the Magnius serve as pre-amp outs while the A30 Pro only has a pair of passthrough outputs.On the specs sheet, there is a difference in the dynamic range capability of the amplifiers, and I believe that it manifested itself in how the layering and depth are presented. This makes the SH-8s’ soundstage presentation comparatively more compressed and blurred together.

The HO200 is unmistakably an SMSL product, where some design elements can easily be found in other SMSL products. But simply improving and customizing an already proven formula isn’t such a bad thing. While it takes a lot of previous design elements, the HO200 has been customized to ensure that the features available with the HO200 can be used easily. While digital may seem to be more modern, both devices can keep a consistent channel balance throughout the volume range. This is done through the use of the switched resistor volume control on the SH-9, while the A30 Pro uses 3 gain stages to maintain precision.The rear of the L30 is quite a bit simpler than the A30 Pro’s since the L30 is strictly limited to single-ended operation both at the input and the output side. So the L30 only has RCA inputs and a pair of RCA outputs. NOTE: this is a brand new products. I cannot test for bugs and issues beyond what goes on in my testing. While I did not find any issues whatsoever, you may find otherwise. If you are squeamish about such things, wait for early adopters to buy it and put it through its paces. Treble is highly detailed, very textured, sometimes highlighted, but it wasn’t harsh or bright with my digital sources. It went sky high, it fully preserved the top octave, I’ve felt driver movements past 16 kHz, especially with Hifiman headphones. It was going for a clean, undistorted performance, with a defined leading edge and outlined contours. If you like your trebles clean and extremely detailed, then this amplifier is definitely for you. A30 PRO rendered bells, cymbals and tambourines in a clean manner, I felt their metallic shimmering, there were playful and impactful but never bright in long listening sessions. I’m reminding you that it is extended in here, so it might pose a problem with bright sounding DACs or headphones, for a perfect match you’ll need a warmer and a calmer digital or analog source (D30 PRO will fit like a glove). A30 Pro has no PRE but only pass through, so RCA in TRS out or XLR in RCA out can't work. TRS to RCA cable might work but it might introduce noise or distortion, TRS is balanced RCA is unbalanced. So there's no telling if this will work properly. Voltage-wise it'll drop half since RCA is not balanced so no issue there. But overall I'm not sure your set-up would be the best idea. You can try though..
