Astell & Kern SR15 and SE100 preview

Astell & Kern is one of those companies that I was instantly intrigued by the moment I saw their first industrial-designed audiophile product years ago — the AK100 — before I’d even heard a note of music through one of their DAPs.

The original, the AK100.

A relatively new player on the high-fidelity block, A&K is a company that launched at the beginning of what was the audiophile-centric, computer-audio boom and has ridden that wave to critical acclaim with unique, standout products like the aforementioned AK100 portable digital-audio player, which made its debut at CES in 2013.

Despite a burgeoning portable-player market, in January 2014 Astell & Kern followed up on the popularity of the AK100 and AK120 with the AK240 and a year later with what I consider their breakthrough, genre-defining audiophile model: the Dual-DAC equipped AK380.

The dual-DAC AK380.

Despite continuing successes, A&K do not seem content to rest on their technological or industrial-design laurels. They continue to push the boundaries of their research and development, the results of which were recently unveiled at a press launch in California of their latest models – the Cirrus Logic CS43198 dual-DAC equipped A&norma SR15 ($699USD) and the ESS SABRE ES9038PRO eight-channel enabled A&futura SE100 ($1,699 USD) – which InnerFidelity covered in June

After conferring with the company’s rep, Jason Henriques, I received review samples of the SR15 and SE100 and decided I would start out by using the SR15 (along with a Naim DAC-V1) to break-in several pairs of new Audeze headphones.

The diminutive SR15 is as gorgeous to look at as it is to hold. It is smooth as a polished river stone, with muscular, angular lines of metal and glass drawing the eye and fingers in immediately to touch and hold. It has an almost perfectly-balanced heft in the hand, and is quick, easy and intuitive to set-up and use.

I had it streaming Tidal Hi-Fi over my wireless network in two minutes and straight out of the box the sound was gutsy, transparent and articulate with a wide, deep soundstage, excellent presence-region weight to both instruments and vocals, deep authoritative bass and airy treble that was not sacrificing clarity for smoothness.

After a quick install of Android File Transfer onto my audio-dedicated MacBook Air 11-inch and loading the SR15 up with a mix of 24/192 PCM files along with several DSD128 albums, I was able to bring the music that much closer to the recorded event over what Tidal Hi-fi had been serving up.

I’ve been doing the bulk of my listening through the new Audeze LCD-4z ($3,995 USD) which are spec'd at 98 dB/1mW and a 15-Ohm impedance. The 4z being driven by the SR15 sounds effortless with a real sense of headroom and grip on powerful dynamic swings. When the 4z is burning-in on the DAC-V1, I use a pair of LCD2 Classics.

With the about 60 hours on the SR15 so far and about 150 hours on the LCD-4z SQ is really opening up.

Taking this combo out on daily walks to photograph the area around my girlfriend’s family cabin, or our home in the city is one of my current favourite pastimes, as the SR15’s size makes it unnoticeable in jeans or shorts pockets.

Next up for a preview will be the A&K SE100, so stay tuned for this update very shortly.

I just bought one and that looks like laser-etching on the back, rather than carbon fiber.

This is from Jason Henriques with A&K regarding the SR15 back: "It is just glass. The only players with Carbon Fibre are the flagship models – SP1000, AK380, AK240. All other players have a glass backing."

Thanks for sending the note, now we know definitively.

I've amended the line in the preview!

Sure would like to know if AK will ever make Tidal available offline. I have an AK Jr. and I sure would buy a new player if they did. I have WiFi in my car but it would be prohibitively expensive to run regular full stream 4G with the current app.
