The SPL Stereo Vitalizer MK2-T is a program equaliser concept which makes use of scientific psychoacoustic technology to process audio signals. The Stereo Vitalizer MK2-T technology has been constantly improved over the past years. The Stereo Vitalizer MK2-T is the tube version of the successful Stereo Vitalizer MK2.

The Stereo Vitalizer MK2-T utilises two 12 AX 7 LPS-double triode tubes. One of them is used within the Mid-Hi Tune filter and gives the mid frequencies even more accurate transparency with a soft, unobtrusive sound. The second tube is used within the Stereo Expander.

The stereo image not only gains more width but also more depth, transparency and clarity because of the pleasant tube harmonics. The treble range is reworked with Coil filtering stages which focus on achieving a smooth, silky sound pattern. The Stereo Vitalizer MK2-T high frequencies are livened up extremely noiseless without them sounding hard or aggressive.
