Astell&Kern / A&ultima SP3000T Copper

■ Equipped with a crossfeed function that realizes a sound image close to that of a speaker
・In a headphone environment where the left and right channels are clearly separated, ear fatigue may increase after long periods of listening. Crossfeed is a function that mixes part of the original signal from one channel and sends that signal to the opposite channel with a time lag to position the sound image in the center. This enables a natural sound as if listening with speakers. Detailed settings such as shelf cutoff, shelf gain, and mixer level allow you to set the crossfeed level according to the listener's preferences.
*Crossfeed only supports PCM formats up to 192kHz/24bit.

■Real-time information confirmed by light
- The beautiful volume wheel of the A&ultima SP3000T is equipped with an LED light shaped to reflect the image of majestic music swirling inside. The LED light that spreads intensely from inside the SP3000T allows you to check the bit depth information of the song being played and the set amp mode.

■Luxury shrunken calfskin leather case included
・The SP3000T comes with a special leather case made of shrink calfskin leather from Perlinger in Germany and Alcantara in Italy. Leather made using the shrink method has natural wrinkles, creating an irregular yet unique texture that enhances the sense of luxury. Unlike regular embossing, it preserves the natural texture of the leather and minimizes discoloration, so the color will remain vibrant even after long-term use. The SP3000T case is made of the finest leather from the Perlinger tannery in Germany.Founded in 1864, Perlinger is the last bastion of calf leather manufacturing in Germany, boasting a tradition spanning five generations. Known for its unparalleled quality, Perlinger's shrink calf leather is considered the finest in the industry and is highly sought after by leading luxury brands such as H.M.C.
