Chaitanya Rona (Hyderabad)
SR 35 is a baby born of SP 3000


It's a small desire to have an Asten&kern player in life but always step back because of its slow UI in previous generation DAP. Don't know how bad they are at UI never had a personal experience but a lot of reviewers have kept mentioning the same point many times, Now Asten & Kern doesn't give a chance for anyone to talk about their UI being slow, and lazy because they came up with NEW UI in my experience they are Good ( Not Great or Nor Bad ). 


Amazing!! It's a warm sound with a great separation of instruments. The soundstage was quite great at this price point. Essentially the sound Asten & Kern trying to deliver is very smooth and relaxed. There is some Air flowing in between every node of sound and it comes quite the natural way the instrument should sound. The imaging part of A&K SR 35 feels like a black background where vocals will be centered and all instruments will be placed around the left and right.

We can definitely feel there is something extraordinary the A&K was doing with their technology built-in. It's something unique when compared to other DAPs.
Coming from Sony, HiBy DAPs can easily say that A&K is outstanding in Sound quality and other features.

QUAD DAC is better than DUAL DAC More engaging sound uplifts the LOW end very well and sounds more rounded sound. 

It really makes you feel a little emotional with its sound quality and separation when you listen to some songs from the albums like " Taal ( Ishq Bina ), Iruvar ( Sasivadane ), Bombay, Any A.R. Rehman sir Song you play makes you feel that emotion carried by the sound. 

SP 3000 vs. SR 35:

Many buyers like me have this question in mind after extensive research on this device by seeing the reviews and blogs of Audhiphiles forms. What is the difference between SP 3000 vs SR 35? Why there is a huge difference in the price level, Are I missing something? 

Let me clear it up for you guys, First and most why Rolex watches are too costly, It's because of their material which is the first thing they are expensive, and then the brand with Unique dail designs that you won't get from Normal watch brands. Finally, there are Luxiuroes and social status comes along with it. 

It's the same here with SP 3000 too. The SP 3000 is built with high-grade-quality materials for its internal components and external body build. They really want their high flagship player to have that build quality in all internal and external parts. It's not the reason to increase their flagship player price tag but they believed with fine material we can achieve a more quality sound from the DAP.

Secondly, They are a well-known brand for flagship players and surely need to add some luxuries for it such as the chipsets and internal circuit structure with the first AKM Flagship chip with Silver layering and little add-on technology for it. The best UI works faster than SR 35 because the player upgraded RAM. Other features Like Roon work better than SR 35. The Bluetooth and Wi-Fi things work the best.

Considering all this there will definitely be a huge price tag for it but when you compare the sound SR 35 is a baby born of SP 3000. Many reviews have mentioned this line and HPZ Guys also have said that the sound was near to SP 3000 but there will be some differences in sound for their extra tech and material. In the sound stage and imagining, there More spacious sound in instrument separation.

Not saying you don't need to waste your money on SP 3000 like that but my intention is that A&K is giving its best at any price point for their customers in sound. Surely you love the sound that comes out of it and you surely going to taste that flagship sound from SR 35 to know what SP 3000 is capable of delivering more. 


1. The Wi-Fi is not stable (Companies like A&K Sholud have taken care here more, whether it's entry player or flagship WIFI Option is very important for a player because it's not cell to have some 4G or 5G networks). 

2. The screen is small for me it's ok my fingers are thin but it's very hard for fatty fingers. 

3. UI can be a little faster. There should be no differences between the software quality compared to flagships. You can have on tech and sound but really not on software that A&K has to learn from other DAP companies. 

Final Thoughts: 

Overall, A&K SR 35 is the best DAP for the price. Highly recommended if anyone not yet in the A&K Family wants to taste their Unique sound and what they can do more with SP 3000. Then SR 35 is the best in class and hope it's almost enough for most of the Audiphiles in the market. 

Feature surely upgrade to SP 4000 If any or SP 3000T as the SP 2000T model comes out but as of now very much satisfied with a product that is enough for me and for my IEMs. 

My review is done with my flagship IEMs

Love this

It's small and fits inside your palm. It's Quad DAC and I don't have premium IEM to experience it. Screen and UI ia just so well done. Off course this sounds bliss. Best in class build. What's missing inside the box is a leather case. Back in 2002 box includes case and IEM. In 2 decades my ears are still the same THANK GOD. Thank You headphone zone team to having sent this in 2 days. Received a absolutely beauty and loving this.

This makes us really happy and we really appreciate the genuine feedback! We're glad that you have such positive thoughts about our team and the company.

perfect DAP...

Value for money with battery life
if you want more base then this is the DAP you want.
the angles display looks really different and awesome.
you get two screen guard for the display and the back which is a life saver for people like me.
pair it with a really good IEM and you are good to go for another 4-5 years.

Hey Lokesh, thanks a lot for the awesome review and we are glad you are enjoying it! Keep the music playing.

Premium DAP with Blissful Sonic Quality

I have been using other Ch-Fi DAPs earlier and this time I wanted to try out the most reputed brand in the world of DAPs.
Premium build quality. Comes with two sets of Screen and Back guards (film) and they are Matt finish which is also great. USB C type cable is of high quality.
While it takes some time to get accustomed to a non-Android UI, but the basic layout is very similar to Android and user friendly as well.
In terms of sonic experience it is wonderful. Width of the Sound Stage, Realistic Imaging, Quality of Layering and Separation are the parameters which should define the quality of the output and it is just exquisite in SR35. Now I hear those sounds / instruments which I had not heard earlier on the same tracks.
No heating issues.
Would have been good to get the Case for the DAP
In a nutshell nothing to complain about. One can just blindly choose this one without any comparison if you are not using high impedance headphones.
Fast delivery by Headphone Zone team !

Thank you so much for your kind words! We're thrilled to hear that you had a positive experience shopping with us. ️ Your support means the world to us! We can't wait to serve you again soon. ✨
