## Description

Astell & Kern SR25 Mk2 The Astell & Kern SR25 Mk2 is the latest and greatest “entry levelInches player yet from Astell & Kern boasting enhanced power, connectivity and speed. The A&norma line of portable audio players from Astell&Kern are designed to be an industry standard to play back high-resolution audio for the masses. The A&norma line is a “Mass PremiumInches product that futures a stunning, high-end, luxurious design and reproduces sound as it was intended by the artist and engineer who originally recorded it, at an affordable price. The Astell & Kenr SR25 MK II is a refresh of the widely popular SR25 player released in 2020. Like the SR25, the SR25 MK II features two Cirrus Logic 43198 MasterClass DACs in dual-mono configuration, but adds a number of new features. The SR25 supports native playback of DSD256 and 32-bit/384KHz PCM high-resolution audio. New features to the A&norma line included in the SR25 MK II are: ReplayGain, which allows the player to automatically adjust the volume between tracks and maintain a consistent playback level.

Review: Superb! - This is an excellent piece of kit. I was an A&K buff for sometime but they priced themselves out, and having paid that money there were various irritating issues. So I moved to Fiio and Shanling and they are ok. This, though, leaves the competition in its rear view mirror. The price is ok, nowhere near as eye watering as some of their previous models. Capacity (1 terrabite card) is excellent. The interface and os is very user friendly. Most importantly, though, the sound quality. It is superb. Very happy with it and would recommend it to anyone.
Review: Avoid avoid avoid you will cry 😢 - The players sound was ok but very overrated. Just after a year the battery swelled so I sent the player back to A&K for a battery replacement this swelled after about 4 months!! I give up !! There is better out there but this is supposed to be a quality brand but I wouldn't buy anything fom them ever again , it's rubbish . My s10 plus sounded better than this .👎

## Features

- The SR25 supports native DSD256 and 32bit/384kHz audio for the first time in an Astell&Kern standard product and boasts performance that cannot be compared with other competitors' products.
- The SR25, which is smaller than other players, has been developed to achieve stable, ultra-high resolution sound. We have developed a new Performance Mode with the SR25 that automatically optimizes and sets the memory mode in the system according to the data size of the source being played.
- As the resolution of the sound source increases, it is necessary to process a large amount of data rapidly. If this part is not optimized, sound breakup may occur. To prevent this, the SR25 uses the new Performance Mode to adjust and optimize the system in order to produce near perfect sound quality when playing back high resolution audio.
- Experience ultra-high resolution with the SR25's Performance Mode, which reproduces even the smallest, minute details of the original recording the artist was looking for, without compromise.

### ⭐⭐⭐⭐ NOT SR25 MK2
*by O***E on 17 March 2022*

It's a great DAP so far, but the product description clearly states it's SR25 Mk2 when it's not. It's the original SR25. I'm not going to return it as I got it significantly cheaper than the Mk2 price and they're not all that different, but as I write this the price has gone up to within £20 of the Mk2. Currently the product description says "Astell & Kern SR25 Mk2 The Astell & Kern SR25 Mk2 is the latest and greatest “entry levelInches player yet from Astell & Kern boasting enhanced power, connectivity and speed.
