Linn has long been a pioneer in the world of HiFi. Its products featured an Ethernet input back in 2007! Many manufacturers today are still thinking about implementing network based audio, while Linn has over a decade of experience perfecting the implementation and performance.
This week at the James Hotel in Chicago Linn introduced its newest product the Selekt DSM. I had an opportunity to sit down with the Linn team to talk about the brand, the Selekt DSM, and listen to the Selekt in two different systems and several configurations.
The Selekt DSM
Linn calls the Selekt DSM a configurable network music player. In simpler, less glossy terms, the Selekt is DAC in one configuration and an integrated amplifier in another configuration. Configuration options can be selected at the time of purchase or installed by a Linn dealer at a later date.
The Selekt DSM without built-in amplification is a great source to be connected directly to an external amplifier. Its built-in volume control eliminates the need for an external preamplifier.
Should the user want to eliminate both an external preamp and amp, the Selekt DSM has available slots for adding amplification (100W/channel into 4 Ohms, 50W/channel into 8 Ohms).
One configuration option that many members of this community will likely opt for is the Katalyst DAC upgrade. This upgrade takes the digital to analog conversion to a completely different level. I had the opportunity to listen to two Selekt DSM units side by side. One had the upgrade and the other featured the standard DAC. The Katalyst DAC upgrade is a no-brainer for anyone interested in the best sound quality.
As a longtime Linn fan I immediately noticed the visual differences between the current and previous DSM products and the new Selekt. The aesthetic focal point of the new Selekt DSM is the beautiful and functional dial positioned on top of the unit toward the front. This looks like a trivial volume control, but upon further investigation users will find it's much more.
Like a little kid in a candy store touching everything in sight, I jumped at the first opportunity to get my hands on the Selekt DSM dial. A typical right and left spin were my first moves, but using it more like a joystick with tilt and press controls was more luxurious. Scrolling through tracks on an album by pressing the right side of the dial and pausing playback by pressing the center felt really nice. The tactile feel of controlling music via mechanical means is a far different experience than swipe, scroll, and tap.
Another mechanical feature that the Linn team really nailed on the Selekt DSM is the preset buttons. Not content to have just standard presets, the Linn team designed the Selekt DSM buttons to elegantly offer information before the users commits to selecting a button. A slight press of the button triggers the display to show how the button has been programmed.
For example, Linn programmed a button to play the album Dummy by Portishead after I piped up and said I'd been listening to that album frequently as of late. I walked up to the unit and slightly depressed the preset button to see the name of the album revealed on the display, but the currently playing music wasn't interrupted. Then I pressed the button fully and the album immediately started playing. It's a great feature that seems to obvious to everyone using it, but I have yet to see it on other products.
P.S. I also call this feature the guilty pleasure preview. I love Taylor Swift's 1989 album and listen to it frequently. When the Selekt DSM arrives for review, I just might pin this album to one of the buttons. On a normal system this would set me up for a tremendous ribbing from my friends should I accidentally select this button rather than the Muscular Manly playlist during a party. On the Selekt DSM this little preview feature could save the day and save me from the obligatory, "it's my daughters preset" lie.
One item that surprised me was the inclusion of a USB input on the Selekt DSM. Given Linn's longtime support of Ethernet based solutions, I thought the company had bypassed USB altogether, writing it off as a temporary input not long for the HiFi world. The Selekt DSM is the first Linn product to feature a USB audio input in the company's history.
At The James Hotel Linn setup two listening areas with the Selekt DSM connected either directly to speakers or through a Linn amplifier. The company elected to use speakers from B&W and Wilson Audio for its demonstrations rather than Linn loudspeakers. This was done to show people that an entire Linn system isn't a requirement.
During the listening sessions I really liked what I heard from the Selekt DSM in all configurations. Connected directly to Wilson Sabrina speakers the Selekt had tight control of the loudspeakers and delivered a very clean sounding source that hadn't been compromised prior to hitting the speakers. The Selekt DSM sounded far superior to another brand's product there for demonstration. In addition, when Linn engaged the Space Optimization feature on the Selekt, the sound quality was elevated even further. The newest version of Space Optimization is available on the Selekt DSM and given what I've heard in my own listening room in the past and what I heard in this system, it can be very advantageous. Space Optimization is digital done right and used for great benefit rather than using technology just because one can.
Listening through a pair of B&W 804 speakers, I compared the standard Selekt DSM to the Selekt DSM with Katalyst DAC upgrade. As a connoisseur of DACs I can unequivocally state that the Katalyst DAC upgrade shouldn't be overlooked. A/B comparisons were very straight forward without volume manipulation or any trickery and differences were easily heard.I look forward to getting a Selekt DSM with Katalyst DAC upgrade in my own listening room to continue the evaluation on an even more familiar system.
When is comes to digital audio Linn has always been about engineering first and foremost. The Selekt DSM combines this engineering heritage with wonderful industrial design and usability aspects usually found in more lifestyle products. As I listened to the Linn team explain the new Selekt DSM and show its features, I couldn't help but hear Jony Ive's voice from an Apple product announcement in my head saying, "With this product we started over from the ground up ..." The Linn presentation and product were very nice. I look forward to receiving the Selekt DSM for further listening very soon.
