Great review Amir. From super-sensitive IEMs to power hungry high impedance headphones this amp excels in every area. If you need just one headphone amp to do it all this has to be the one. Let's hope the price is going to be competitive.
Sounds amazing! Also using a 1/4 to XLR adapter for the XLR input on front. Really beautiful sound. Picked up the D30 Pro also. Using as a pre with Yamaha MGP32X mixer. Absolutely beautiful sound especially with Apple Music doing 24/192 lossless! Lovely. Thanks again for the review. ✌🏾

I'm an Aune X1s Pro user. I've just ordered A30 Pro today. It just looks like an endgame for single ended headphones, at least for now. What headphones do you use with k5 pro?
Being an engineer, I like this approach. I recall seeing this review before and was a reason why I got this in for review from Amazon. Using Sundaras, I had the Singxer and A30 Pro in at the same time (both in balanced mode) fed by a Topping E50 with Apple lossless music ripped from CDs. Ended up with the Singxer. A30 was a bit sharp for me in the trebles. Maybe the Sundara has issues in upper trebles? (by the way, I had EQd them per Amir's other review with APO).
With this one on the market, they are kinda cannibalizing themselves, no? The a90 stays only for people that need a lot of power on their headphones? Or there is another reason to go for the a90 instead of the a30 pro??
As usual, an excellent, thorough and in depth review Amir. Can you review Aune X1s 2021 edition and compare them with A30 pro? I've heard they improved the circuitry in this edition. 🙂
Hi, I really enjoy your videos. lately, I´ve seen an interview in which you told the reporter that you worked for Sony in computer systems but started to sneak in audio. I just have a question on your experience in Sony: I compared the broadcasting series of products (amplifier of SRP line) and found that sounds way better than sony premium line. Is correct my view? are professional equipment better (or sound better) that home premium gear? I compared (with my human ears) a jbl urei 6260 with a threshold, mcintosh, and other amps, and found it unbeatable. The same happened when compared home gear with professional hafler amps. Is correct my interpretation? Best regards and please keep posting.
You can but it is also implicit in the measurements shown. Just divide voltage by the load used in the measurement and you have current. Someone did the math on ASR forum thread.
Just a question about the headphone volume imbalance vs volume position graph. Is the channel difference, ie the blue dotted line, normalized according to the output RMS voltage? Otherwise even though the line remains flat during most of the test, the actual ratio between the difference and channel level increases significantly. Thinking again, I feel like it has to be normalized to the output voltage, but in any case it is good to check with the expert!
DX7 Pro has higher than desirable output impedance. A50s has much lower output power (will not get as loud as A30pro which can get extremely loud), but depending how you listen your headphones it might be enough. I would go for A30pro + D10pro (upcoming, not released yet).
I only do those for DACs. I could add them to amps but at some point you wind up with so many graphs that people just skip over them. Occasionally I have done multitone.
Excellent review like always 🙌🙌🙌🙌🙌 i wonder if somebody was trying to put dirt on topping 🤔🤔🤔🤔🧐🧐🧐🧐🧐 because L30 was gonna be number 1 cleanest headphone amp. Topping is not a rookie brand. Just saying there can be some weird people out there doing dirt for a dollar. 🧐🧐🧐🧐🧐🤔🤔🤔🤔🤔🤔
My sifting through the opposing opinions, I am landing on that the A30Pro seems like a great buy, but the D30Pro might be a little out of it’s price point - does anyone have any opinions or recommendations for similar priced better value DACs I can pair with the amp, or for example, would paying a bit more for a Gustard x16 (seemingly highly regarded amp + BT) be a reasonable consideration? Or is that all nonsense and the D30 pro is a perfectly fine companion at it’s price?
If only thing you want is audio from PC, then you can get Topping D10B and electrically (and audibly) it will be as good as 2k$ neutral DACs. Well, it electrically it can be even better than some ultra high expensive DACs since they are more focused on audio mythlogy than performance.
Hope this is gonna cost more than the L30 or I'm getting sick as I have just requested a replacement instead of just sending it back to amazon and I would really get annoyed if I could get this for almost the same price as the L30.
I just quickly compared A30Pro and A90 ASR reviews, if I read the measurements right, does the cheaper A30Pro produce more current and power than the A90? Then objectively speaking, the A30Pro is better than the A90?
Single ended yes! Balanced output, not even close. A90 still king. One thing to notice, the A30 Pro is ONLY a single ended output amp, meaning that even if it has balanced inputs and balanced outputs, you ONLY gonna get single ended power. A bit of false advertisement by the looks but once you read specs, it does say is not a true balance amp.
@@christianhawkins6947 Internally the A30 Pro is not a balanced amplifier, however they provide “balanced” XLR and 4.4mm connections on the front for convenience. That way you don’t have to buy a new headphone cable if you have a balanced cable already. A true balanced amp, like the Topping A90 would provide double the power from the balanced connectors than it would from the single ended connectors. The A30 Pro has the same power output regardless of which output you use, but this shouldn’t be a problem as it produces so much power anyway.
Thank you for this but I have to ask is this truly a balanced amp? There are so many reviewers with reviews claiming this amp is not in fact balanced. One even claimed in a response to me that he talked to Topping Engineers and they confirmed to him that it is not a balanced amp. If that is true then those same peopled lied in all the marketing materials and information they provide for this amp. I would be really thankful for your help on this issue. I realize it comes dangerously close to creating drama but I want the truth. I'm tired of paying a premium for devices that are being marketed as balanced that are not in fact balanced. Thank for your time if you read and reply to this comment. I have this amp on the way basically because of this review. I got a pretty good deal on ebay for an open box unit... Oh, sorry this comment is so long after your review and thank you for your site that I've been reading the comments and reviews on it.
It has balanced input connectors which is way more practical than balanced amplifier architecture and output. Balanced audio line connections are standard in pro audio.
They do its called Topping Pre90 you need to get Pre 90+Ext90 then you have two rca inputs and more than 3 xlr inputs and 1 rca out and 1 xlr out. All xlrs are balanced.

Only buy from Amazon or Apos , I bought from China , D90 mqa after 5 months flickered and died . $130. Canadian to return it . $80 by ship ( 3 months) . Very unfortunate, loved it . My A90 still working .
@@jd2plus2 I bought a benchmark DAC2 a few months ago. Very cheap because internal power supply was defect. The exact replacement was not possible because mot RHOS confirmed. So short looking to Amazon and bought an external power supply with better specifications and adapted the housing of the benchmark for a dc plug instead mains connector. The results are amazing. Works really fine with less heat dissipation in the housing. Perfect deal.
This is not a balanced amplifier, not that it matters. It has balanced headphones output plugs for convenience, but the electronics driving them are not balanced. The HPA4 is designed the same way. Also, when using the passthrough function, it appears this amp does not control the volume. It would have to be controlled by the DAC, so, when listening to headphones, you'd want your DAC in DAC mode, but you'd have to switch it to Preamp mode when using the passthrough to control the speakers. If you forget to switch modes, and turned the headphones amp off, the full volume of the DAC would be suddenly sent to your powered speakers! I'm not sure I understand this design choice.
Your title says Balanced amp, but is advertised as a powerful single ended amp, even tho it offers balanced outputs, it performs at single ended power. Can you please clarify and perhaps adjust your title.
You're correct. This is clearly stated on Topping's website. The biggest issue I see with this amp is that the preamp output, which most people will use to run powered speakers, is a simple passthrough with no volume control.
There seems to be a bit of conflicting information between this video and the written review. Are the rear outputs pre outs or just passthroughs? Apologies if I missed a clarification somewhere.
Apologies for that. When I did the video I implicitly assumed it was a pre-amp which it is not. The text review is updated with a note to reflect that.
@@AudioScienceReview Amir, you can choose to "pin" your comment with this information to always appear at the top as the 1st Comment so everyone reads it first. It's a good practice when these types of corrections or new information arises, such as this or the MSRP $. Also can edit the video description area as well.
Amir, i know you are new to TH-cam but i gotta tell you, you do a bit too many mistakes in your editing, "Do Fancy Audio Cables Make a Difference?" title there in this video, should not be there. Also in your full size clips Audiosciencereviews text is spelled wrong (which is also the same thing in your other videos). No hate at all from me here, i love your videos but these things could be fixed.
Does anyone still listen to ASR and Amir!? You shouldn't! I have been working as a computer engineer in China and Japan for most of my life. I have meet audio engineers in Japan working for Fostex, Denon, Onkyo, Marantz, Rotel and Sony. I have met Ken Ishiwata. I understand Chinese and I am near native in Japanese. Audio Science Review is not to be trusted as they are too corrupted and fully bribed by cheap Chinese audio makers especially by Topping and cheap audio makers in Shensen. What they produce is not what you will enjoy as a critical listener and the quality is poor. What ASR focus on is THD, that as a coincidence, is what all Chi-fi makers are focused on totally neglecting what consumers enjoy. ASR is doing measurements to make Toppings look good but in the end you won't enjoy as a listener. I have hardly any Chifi gear, I use high end stuff from Rotel, IFI, Fostex, Rega, B&W, REL acoustics, Audeze, Denon and Marantz. One exception is SMSL D1SE which i use as a DAC. ASR is a total waste of time. I was a senior member there but I decided to fuck them badly because of their bootlicking of cheap chinese makers. If Amir stop licking their boots he will become a homeless beggar. ASR is irrelevant and as a consumer your listening experience won't improve by following what they say. ASR is declining and will vanish... RIP ASR.
There is confusion about the term balanced in headphone amplifiers, but I believe the video title references the fact that A30pro has balanced inputs option.
Clarence - You're one of those huh? "Only the 911 GT3 is a real Porsche". Ya know, not all of "us people" need absolute "perfection" in audio. I have been on both sides with photography equipment. Guess what, unless you do it for a living, and sell/make $$, there's little point for "most people" to blow excessive amounts of money chasing that very last 5% of performance. This is true across almost all consumer electronics, and same in the automotive world. Not everyone has endless disposable income. Some people are fine with "good enough" for their purposes. Do you actually have anything of SUBSTANCE to contribute or are you just in "low energy" mode with the short negative comments? Maybe change that diet of yours will lead to less anger issues...

You're correct. This is clearly stated on Topping's website. The biggest issue I see with this amp is that the preamp output, which most people will use to run powered speakers, is a simple passthrough with no volume control.
There seems to be a bit of conflicting information between this video and the written review. Are the rear outputs pre outs or just passthroughs?
Apologies if I missed a clarification somewhere.
Apologies for that. When I did the video I implicitly assumed it was a pre-amp which it is not. The text review is updated with a note to reflect that.
@@AudioScienceReview thanks for letting me know. the passthrough is better for my system anyway!

Amir, you can choose to "pin" your comment with this information to always appear at the top as the 1st Comment so everyone reads it first. It's a good practice when these types of corrections or new information arises, such as this or the MSRP $.
Also can edit the video description area as well.
Second!!!! 🙌🙌🙌🙌
I want it it’s cute
Just ordered this unit to try and drive some argons unbalanced. Hope it’s enough lol
Waiting for the price!
$349.99
I have 16 ohms at 1kHz Sony headphones, will they work well with this amp?
Yes.
Went from Asgard 3 to this.
How does it compare?
Cool, NwAvGuy has a TH-cam channel 😉
Warranty with Topping? When it goes wrong...
Amir, i know you are new to TH-cam but i gotta tell you, you do a bit too many mistakes in your editing, "Do Fancy Audio Cables Make a Difference?" title there in this video, should not be there.
Also in your full size clips Audiosciencereviews text is spelled wrong (which is also the same thing in your other videos).
No hate at all from me here, i love your videos but these things could be fixed.
Does anyone still listen to ASR and Amir!? You shouldn't! I have been working as a computer engineer in China and Japan for most of my life. I have meet audio engineers in Japan working for Fostex, Denon, Onkyo, Marantz, Rotel and Sony. I have met Ken Ishiwata. I understand Chinese and I am near native in Japanese. Audio Science Review is not to be trusted as they are too corrupted and fully bribed by cheap Chinese audio makers especially by Topping and cheap audio makers in Shensen. What they produce is not what you will enjoy as a critical listener and the quality is poor. What ASR focus on is THD, that as a coincidence, is what all Chi-fi makers are focused on totally neglecting what consumers enjoy. ASR is doing measurements to make Toppings look good but in the end you won't enjoy as a listener. I have hardly any Chifi gear, I use high end stuff from Rotel, IFI, Fostex, Rega, B&W, REL acoustics, Audeze, Denon and Marantz. One exception is SMSL D1SE which i use as a DAC. ASR is a total waste of time. I was a senior member there but I decided to fuck them badly because of their bootlicking of cheap chinese makers. If Amir stop licking their boots he will become a homeless beggar. ASR is irrelevant and as a consumer your listening experience won't improve by following what they say. ASR is declining and will vanish... RIP ASR.
It is not balanced; bogus product & review.
There is confusion about the term balanced in headphone amplifiers, but I believe the video title references the fact that A30pro has balanced inputs option.
How many headphones will be destroyed?
About the same with other amplifiers.
None.
@@r423fplip How many other amplifier can pump >5W in your low ohm headphones if you flip the gain switch to high?
None were harmed in the creation of this video content.
Just a garbage review
Hey Clarence, where is yours?
trol
Clarence - You're one of those huh? "Only the 911 GT3 is a real Porsche". Ya know, not all of "us people" need absolute "perfection" in audio. I have been on both sides with photography equipment. Guess what, unless you do it for a living, and sell/make $$, there's little point for "most people" to blow excessive amounts of money chasing that very last 5% of performance. This is true across almost all consumer electronics, and same in the automotive world. Not everyone has endless disposable income. Some people are fine with "good enough" for their purposes. Do you actually have anything of SUBSTANCE to contribute or are you just in "low energy" mode with the short negative comments? Maybe change that diet of yours will lead to less anger issues...
