Topping A30Pro Review (Balanced Headphone Amplifier)

This is a technical review of the Topping A3Pro balanced headphone amplifier. It was kindly sent to me for testing by the company. This is also a tutorial on how to read objective measurements of headphone amplifiers.

P.S. Forgot to change the text in the video from last video ("Do Fancy Audio Cables Make a Difference?") to this one. Sorry about that. :)

The explanations of why these measurements matter, thresholds electronic and audio make these reviews/analysis better than anything else for a consumer. Thank you, thank you, thank you. Subscribed.

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.

This amp is far more perfect than anyone could ever need.

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.

Hi . How to connect this amp with sound card AIM SC808 ?

[nzed]

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.

Which of Toppings offerings has the R2R ladder?

Topping... where do you get this devices from?

[andysummersthxcinemaandmyc]

Amir, get some liquid cooling and test this again see if the temperature change makes difference.

S.M.S.L. SH-9 vs. A30 Pro? Which one and why?

[apkenna]

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.

Amir, i know you are new to Youtube 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.
