What you are doing for the industry, to challenge manufacturers in improving products on a scientific basis, is PRICELESS, and ultimately increases the possibility for all of us to enjoy music as an art. That is why you deserve the highest possible respect, good luck for youtube channel, i'm a subscriber!

Welcome to KZfaq, Amir. I am an electronic technician, audiophile and singer. I have been following your great work online. I am subscribed to your channel.

Nice to see you here!

This is going to be HUGE!!!! Thanks for making this video Amir, and welcome to KZfaq! Time to spread the word on the interwebs...

I've been reading your forum posts for a year now, I've always had questions about the various measurements and the best-case scenarios. This explains all of them. Thank you so much.

Great to see you on youtube! The whole internet is eternally grateful for your efforts in bringing back the lost 'science' into audio reviews. Thank you.

Welcome to KZfaq Amir! It's been a long time coming. It's great to hear your voice after lurking around your website for the last 3-4 years. Now we also get to see a video review from the top professional reviewer out there. This will add a whole new dimension to the already amazing reviews from your ASR website. This is great news! Congratulations!

The Maestro himself! It is such a pleasure to finally see you. The video is great to enhance the test results. Although there was nothing new for me (I am an Audio Precision user as well and work in a similar field), I emjoyed it.

It's sooooo weird, but quite nice to finally put a voice behind all of these reviews I've read, LOVE your work! Maybe a video where you go over how you measure stuff to finally dispel the head-fiers and such?

Thank you, Amir. hope this becomes a regular thing. Your sharing of knowledge is always appreciated.

Happy to see you've begun to do video reviews! The measurements and data you provide are super useful and interesting! Glad to have a face to put with the name finally! Best of luck to you with the channel!

Congrats for the first KZfaq video. Just liked and subscribed. Thanks for the review again!!

Congratulations to your first appearance here on KZfaq. The forum you have established (ASR, Audio Science Review) is indispensable, including the contributions of so many collaborators. I am probably not he only one who is interested in learning how measurements work, what the differences between good and badly constructed dacs, amps etc. are and what the graphs and figures mean. Maybe someday you could show how distorsions and noise sound while the deterioration is depicted on a monitor. Consumers will be able to decide for what kind of performance they are willing to pay. Thanks in advance, Amir.

A whole new era... Thanks Amir for all your hard work!

Nice to finally met you in person, Amir! I'm a fan of your work, that shine a light on the obscure audio market. Very Welcome to KZfaq!

Great to see you on KZfaq Amir. Loved having the explanations for each graph, and listening to your comments. Thank you for doing this.

Welcome and great to see you on YT, Amir! Looking forward for more of such videos, perhaps some tear-downs too. Thank you!

The legend's first video without any fanfare, marvelous ~!

I've never posted on the website, (yet!), but I instantly subscribed to the channel. First class Amir, and my Thxs. ... Now I'm booked in to see my analyst as I just can't get a certain avatar out of my head!

Hey Amir. Love your videos. Purchased the Topping A30 Pro (it’s a little moNster, love it!) and ordered my D30 Pro today so in about a week I’ll be set up quite nicely; based in large part on your extremely technical and precise testing. Thanks again and take care.

Hey Amir, thank you very, very much for all the time and effort you have put in sharing your knowledge and experience with the audio community - it's absolutely fantastic. Wishing you every success with the new Channel, cheers Stewart

It's great to see you on video Amir! Great job. You present like you've been doing it for years :)

I purchased this morning the D30 Pro + A30 combo after browsing some other channels and forums for a couple of weeks. Later today I found your channel and your reviews are giving me a lot of joy. I also have the KRK Rokit RP5 G4 speakers, so it seems that this channel was made for me, hahaha. Many thanks for all your technical explanations and for making your videos right to the important points without adding any non-sense like other channels do. You are amazing!

I really enjoy how you explain what the measurements mean, I thought I knew but your video does a better job than just text. Keep it up

Just subscribing to your channel... I found even more interesting following your tests and measurement descriptions through a video. I'll take the time needed to watch at the videos you explained the individual relative measures too. Thanks a lot for your work Amirm! 😉

Thanks for the review, Amir. Long time reader, saved me a lot of money (or gained me a lot of performance at same money spent) thanks to your reviews. Welcome to youtube!

topping did it again.. :) great summary at the end too. i read so many of your reviews on the forum, but man, its so good to have you walk through these tests cause I didn't understand much just by reading. :)

The absolute best technical reviews of audio products! Keep up the great work!

This is the most overdue KZfaq channel! Looking forward to some great videos.

Glad to see you make a KZfaq channel! This made my day :)

This is incredibly welcome! Ever since I came across your site I've been thinking KZfaq would be a nice place for this. Very educational and certain to reach a new audience.

Great video Amir! Hello from the forum!

Thank you for your good work. As a newbie, I genuinely appreciate your explanation of each chart and tests. Thank you very much

Great video going through the measurements. Really helps out in putting the numbers in to context for someone that can't relate the measurements to anything really.

Thanks for this video. Your explanation of measurements were immensely useful for a newbie.

Very clear and concise review. I appreciate your work! I can't wait for a loudspeaker review.

Great first vid Amir, thanks for all your tireless work for all us audio nerds :)

Congrats to your new channel!

Awesome. Great work Amir. Can't wait for more of these.

Great work Amir, many thanks for these videos and your contribution on the forum

Fantastic video Amir, I really appreciate the addition insight into the measurements.

Great to finally see you, and I hope this will be the first of many!

Hey amir, lurker from your website here. Just wanted to say I really respect and appreciate what you are doing. Purchased gear based on your recommendations.

Hah! Found this channel through the algorithm. Haven't visited the website for a while, so this was really out of the blue. Really like your work Amir 😊

I really appreciate your work keeping the manufacturers honest! Budget high performance hifi has never been better.

Love the format! You're a KZfaq natural! Nice work on lighting and camera, too. 👍

Great video Amir, I’m happy you are on youtube now.

Thanks for taking the effort to make a video and explaining everything!

Thank you for your effort and for taking your time to share it with us on screen.

That was a great idea, nice to see your reviews also there! Btw, you are a KZfaq influencer now! :D

First video and already really good production value ! Have you done video work in the past ? Continue like that, it's great !

Loving these technical reviews!

Oh my God, Amir is a real person! ;) ...great video, hard to believe that was your first video, so well made, so easy to understand. To tell you the truth I did not expect that from a hardcore engineer like yourself, obviously you are a multitalented person. And of course I clicked on the subscribe button and I cannot wait for more of your informative videos.

Nice to put a face to the words on the forum! Great review as always.

The legend himself! Thanks for all the great work you do!

Thank you, I was waiting for this (both the review & channel).

You are a high end manufacturer's nightmare but thanks to reviewers like you we get better products for less money, keep them coming.

Who else wants this reveiew over forum reveiws. Dont have to scroll through tons of arguments. Thanks Amir, glad to see this happening.

Great to see you're expanding to KZfaq as well.

have a good start Amir! Been waitting for this!

Finally on KZfaq!!!! Can't thank you enough!! Will you review the Geshelli JNOG at some point? Best regards!

Welcome to youtube Amir!!! Best wishes to you and your channel!!! :)

Nice to see this happening, Amir - and with your usual attention to "fidelity", I noticed that the lighting and sound for your video are very good on your very first post. (I cannot believe how so many KZfaq audio "reviewers" don't have clue about how to produce good voice sound quality for their own videos, yet claim to be audio/sound experts.) As I write this comment, I see that the up/down vote ratio is currently 209 to 5, but the naysayers didn't post their criticism. Last year I bought a Topping DX7s DAC/HA to get the good balanced output DAC, but this unit would be even better for my application, because I don't use headphones. (I see one of the $175 BenQ Genie curved LED desk lights behind you in the video. There is one on my wish list at Amazon, but I am hesitating. Is is really versatile and good enough to justify the high price for this old guy whose vision, like his hearing, is not what it used to be in the past? Lighting near a computer screen is tricky, because sometimes one would like to light up things on the desk while not washing out the screen image.)

Hi, I like your reviews very much, the speakers and headphones too, fantastic !

Amir, as a fellow Microsoft Alumni (Fed 93-00) I am proud of the work you are doing. I have started my own channel DIY HiFi Life that you may find interesting. Cheers.

Glad to see you on KZfaq!

I got 2 of them on Canuck Audio Mart just because of your review. For 300$ CAD each, those are incredibles!

Nice to meet you, finally! Subscribed.

Long time fan of your hard work. Would love to see a casual zoom chatwith zeos or Joshua Valour or bggggaggaaaarr one day, lax podcast style. Cheers!

Great to see you on KZfaq - Thumb UP.

Love these technical reviews Amir, the detail and accuracy you put into each one is greatly appreciated. I often hear you say the the threshold of audibility is about -115 dB. That seems like a very conservative figure and probably only achievable in a very good anechoic chamber, the typical listening room as measured using a calibrated SPL meter it typically 40 to 45 dB. Considering the threshold of pain is generally listed as 120 dB it seems almost impossible to hear anything below 80 to 85 dB. What's your opinion on this? Thank you.

Never clicked 'subscribe' and 'bell' so fast in my life.

first!!!! what a surprise glad to see your gonna build a youtube presence. your channel is gonna do really well. big fan!!! Glad to see your not some young arrogant person. =)

AMAZING review for a very good DAC .. Thanks Amir ...

Finding your KZfaq channel was absolutely fantastic! Does anyone or even you Amir know when this DAC will see a release? Again thank you for your contributions to the audiophile community.

Thanks Amir for making the jump into KZfaq. After reading your forum for the last 2+ years and going over so many graphs, this concise clear yet very detailed explanations by the man himself is a treat.

Amir, you will earn a lot of money with this channel, you can forget the mugs now! Thank you so much!

Listen to my A30Pro feeding into my Schitt Asgard3. What a combo. Beautiful sound stage, natural vocals, and far more relaxing than an ESS Sabre DAC. I mean this DAC is solid gold even minus MQA decoding or Bluetooth. Trying to get a good sounding DAC has been a chore for me. Thank god. Finally found what I'm looking for. Bravo Topping and Cirrus Logic (Wolfson).

Welcome to KZfaq Amir!

Great review with 1 request for future videos. As I'm watching on my phone it would be great if you use a split screen only now and then. The graphs are much easier to read full screen.

Absolutely brilliant youtube debut, excited to see what comes next!

I have come to learn its not just about the technical specs, total accuracy that is important but t is the over all presentation be that sound and appearance of the hardware wise that suits the listener.

Indeed, welcome, and great product.

Hello Amir, nice to see you on yt. A good feeling to see no High-End-Voodoo ;-)

Who knew Noah Levenstein had a spectrometer? :') Keep up the good work!

TOPPING products are getting better and better with each release, Amir. :) - LiolJohn

Finally, a face to a name, a face to an avatar! Thank you for your important work.

Most excellent! Would love to see you do the same with a Primaluna Evo 100 tube DAC. Welcome to the tubes! Ha ha

Thanks for your work!

Topping equipment measure so well, the company basically seems to be in competition with itself these days. Impressive.

AMIR MADE A VIDEO !!! Added you to my subscribed list !!! Welcome to the KZfaq community !!

Excellent content. Excellent video.

Спасибо тебе, друг! Очень важным ты делом занимаешься! 👍

First video?? That was really really good. Do you have experience in other video work?

Great review! I wonder what the release date is.

Nice review!

Any SQ comparisons/differences between topping D30 pro vs the topping D70s MQA? I have found CS and AKM dacs similar sounding with AKM having a bit better definition.

Welcome to the YT world! I will be on the channel from time to time and no the measurement only crew is not going to like my takes just as they don’t on the forums.

Hi Amir, can I run optical out from my Anthem AVM 70 into this type of dac for similar performance as your review? Is it not recommended to do so and just connect a streamer directly to the DAC and then to my amps?

Yay, I post in the forums. Very glad to see you are a real😅
