The SP4000T is a flagship that brings together the technical expertise and sensibility that Astell&Kern has accumulated over many years. The analog sound unique to vacuum tubes and precisely engineered digital circuitry harmonize within a single device, allowing users to freely shape the tone they desire. At the event, we demonstrated this SP4000T-exclusive sound in person and let attendees confirm its true worth.
The response from those who listened to the SP4000T and Clarus paired together was especially enthusiastic. The moment when attendees experienced with their own ears—not through words or photos—the sound completed when an earphone sharing the same philosophy meets a flagship source was, above all, invaluable.
