DAC and Head-Amp you've been waiting for 

Great review. Really like that you got right to the point and showed us where it stands.

I bought the DO400 two months ago based on another YT reviewers' video. It seemed to have all the features, top-of-the-line components and price point that I was looking for. I'm quite happy with my purchase and also glad it gets your stamp of approval as well.

I really liked the DO400. Excellent combo!

Again very detailed review 👍

I dont understand how is it that the Mojo 2 is so good. Loved the review, thank you very much for your videos

Thanks, nice review!

Thank you for your reviews. The way you discribe the sound in your reviews is really is amazing. Could you review the new smsl vmv d2r. It looks unique, not like a tipical smsl product and so far there havent been any reviews on the internet. Thank you!

I really love your reviews, you have a way of describing devices in a way that is relatable and easy to understand, and I really trust and relate to your opinions. I also love SMSL products, I have an SU9 with DA9, SU9pro with SH9, and DO300 with a Yamaha Amp and they are all great, what I don't like is that SMSL is constantly improving their products! It sounds like the DO400 would be comparable, if not better, that the SU9pro/SH9 combo, anyway they are definitely serious about providing great sounding products.

So many good DAC's out there. The differences are very nuanced. SMSL seem to be a safe bet for a first DAC buyer on a budget.

Excellent video, thank You! I'd be happy to hear a review about DAC/preamp combos for desktop setup with active loudspeakers.

Thank you Excellent presentation and comparison. Please review Smsl a0300. Thank you

Thx so much for this review. I bought the DO200 (after watching your video too) and happy with it but I would like to upgrade to DO400 or even VMV D1SE2 but I a waiting your review before doing it!

🙋‍♂️GREAT TO SEE YOU SRBJ…I HOPE YOU ARE DOING WELL 🤗👍💚💚💚

Would love to see you review audylitic ah90. Thank you for all you do.

So after many many months, I have purchased the Do400 and have paired it with the Topping A70pro. It is amazing. It’s a 360 effect and plucks in guitars have never sounded more real. I’m hoping I don’t have fomo in the next five years because this was a long process. Waiting on newer xlr cables to see if there is a difference. Gonna go the mogami 2549 cable route next.

Cool runnings

Great review as always! I was curious if you will review the ef600?

Nice review but the new Gustard ADUALYTIC AH90600 seems a competition that is worth comparing against this system. I am in the market for sure, but really hope to hear from you contrasting these under €600 dacs.

I currently have a xDuoo TA-05 Amp with a SMSL Sanskrit Mkii, which you both reviewed. Do you think this would make a significant upgrade? Or should I look at higher end stuff?

Hi am i going to get thr same sound signature with the DO300 EX. Just as a DAC.

Thank you for the nice video. I have a question. I would like to listen to the 2 headphones at the same time (myself plus a friend). Will DO400 will drive the headphones and XLR output at the same time, so that I can listen to the second headphones on my integrated amp?

Can i ask how the DO400 performs with sensitive iems, in terms of hissing/noise floor? Im hoping to find a desktop dac amp with an inaudible noise floor for sensitive iems

i just bought the do 400 for 350 euros in used good condition from amazon

What's the difference compared with DL300? Have you planned a dedicated review? I like your greatnreviews 😊

Hi iiwi, im curious about do400 but i have a topping dx3 pro + and an ifi gryphon so i would like to know if i would get a much better sound from do400 than these two, i’ll be using it with my Klipsch rp600 m2 speakers, would you mind giving me your opinion pls

Does it have a DAC only mode? Can it function as a pre-amp?

hi, i used this. i got a Problem. PC - DO400(by USB) output Line(xlr, rca) and play music, youtube, anythings .. rised 'Tik' noise stop playing after same 'Tik' noise do you Check this?

Can’t decide between the DO400 and the K9 AKM. Do you have a recommendation?

what you mean by neutral in sound i have fiio k7 i wanna upgrade to flagship dac amp ? whats your recommend ??

I have a question. If I already have the SMSL SH9 AND SU 9N. HOW WOULD THIS BENEFIT ME.? THANK YOU

you would help me a lot if you recommended what I should buy for the aune s17pro, which DAC is suitable for the smsl su-10. SMS up to 300. smsl do400 they are very similar, I understand that there are many more like me, but I hope I’m lucky and you answer in return I will share information I’ll share my experience, I have a do400, the forum and I encountered a problem that when you turn off the device for more than 10 hours and change the digitization from standard 44.1 to higher, then after turning it on it rattles very terribly and this is very unnatural and scary, we haven’t figured out what the problem is We updated the firmware on the forum, it didn’t help

Thanks for this review, had been waiting for it! What are those acoustic panels you have in the background? They look very nice, can you tell me the name/brand?

How does this compare to SMSL DO300?

anyone else waits for the drum hit? :D that should be in you logo as a signature for your brand....on another note when will you have the dx9? :P thank you for reviews :*

A question: I have some issues with the DPLL, I can't set MIN but have to stay 7/8 or the sound is interrupted. I don't know if it is the DO200, the optical cable or the LG C2 output ... what could it be? Which cable do you suggest?

Thanks for your review and suggestions relating dpll, a question: using this dac with fixed volume it should be set a 0 or +2 dB?

Sounds like a m500 mk II/III successor. Too bad your III never materialized. You never know with SMSL, though. I think they have competing design teams.

Hi will you be reviewing the Fiio K 19?

Congratulations on the analysis! I use a Topping D10s connected to a set of Edifier S360DB active speakers. Do you consider that I will have any significant gain if I choose to upgrade from the D10s to the DO400? Thank you very much!

Hello Srbolyub. I am one of the fans of your channel. This is not the first time I am writing to you. And as in previous times, I would like to get your advice based on your experience. My system now consists of the following components: Epos M12i speaker system, SMSL AO200 mkII amplifier (within a year I plan to buy a classic transistor amplifier). Until recently, Matrix Audio Mini-i 4 worked as a source and DAC. And as you described this source, it really worked perfectly with the mid- and high-frequency range. It lacked low and mid-low frequencies for me. And in general the sound seemed without substance. I'm currently looking for a new non-streaming DAC under $500. I looked at your review of the SMSL DO400 DAC, and as I understand it, it is very similar to the SMSL DO300 and Topping E70 Velvet DAC. These devices are right for my price. I would like to know from you whether there are any differences between these devices and the Matrix Audio mini-i 4? And are they better than Matrix? And maybe you can give me advice on what other DACs I can look at so that the sound quality is higher than in Matrix? Thank you very much in advance for your time and advice!) I wish you all the best and good health!)

Интересное имя , а обзор огонь , как всегда .

Can you review the geshelli socketed AK4499 with Sparkos Opamp which also is in the 500$ price range

What would you go for between the DO400 and the eversolo Z6. Using as a DAC for a good hifi amp?

❤

Hi my friend ! i am interested in the DO 400 [for dac use only] and i'd like to know whether the SU 10 justifies its double the price or not Thanks in advance

Hi, very nice review. Is this amp dac combo overkill for Sennheiser HD600? If so what would you recommend for dac amp combo for my headphones which are connected to my PC?

Ah, time is moving on. With DACs it makes it tough to know whether to buy a new DAC or last year's darling DAC. How would you say the D0400 compares to the SU-10? And if you had to choose between a SU-10 and the Denafrips Ares II -12th, would you go with the Denafrips? They are within $100 or so of each other when on discounts. Thanks!

Hola compré el SMSL DO400 en oferta Aliexpress por $380, me llegará antes de fin de año. Ojalá puedas revisar el SMSL DL200 que cumple la misma función pero es más barato $170, muchas gracias

Do I understand correctly that it makes no sense to connect this device through its balanced outputs to the unbalanced RCA inputs of my amplifier (NAD C356BEE)? After all, in this case, only two contacts of each balanced output will be used, not three, and this will give the same 2.5 V that is on the unbalanced output of the DAC and will not give any advantages of the balanced signal?

Hi IIWI, which current Topping Amp is better for AKG K702 among L30II, L50, L70

Odakle je pametnije naruciti ovaj dac/amp kod nas?

Srboljub, thank you for the deep analysis and valuable review. 1. Would you consider changing the approach and extending your comparison to evaluation notes on your website? You have made many reviews and I understand that the simplest way is to compare to the current accessible devices. But I remember that you sometimes can recall your previous evaluation for currently unavailable for you devices and use it as a relative benchmark. 2. In my opinion, the branches SMSL and Topping are the most comparable companies by wide DAC production on the same price levels, features, functionalities and sound qualities. So could you compare the sound quality SMSL DO400 to the same price point DAC: Topping D70 Pro OCTO and to the the same DAC chipset (ESS 9039 PRO) - Topping D70 Pro SABRE as well?

I can buy DX5 (non lite) for 240 euros

What the hell is a DAC?

great review having Loxjie D40 pro I found myself difficult in pairing a new dac for my topping a90 D90 III is great but at a price nearly doubles that of DO400

I have a question. If I already have the SMSL SH9 AND SU 9N. HOW WOULD THIS BENEFIT ME.? THANK YOU
