SL-103
£32,800 inc VAT
The Masterpiece Series has been the internal roadmap for quite some time at Vitus Audio.
Their engineers have spent a long time developing the two chassis MP-L201 Masterpiece line stage. After this big achievement, it was clear that the team had to take a serious look at a replacement for the SL-101 and SL-102 line stage.
They didn’t expect that the improvement in performance would be so dramatic. After many hours of refining, a brand new design was born in the form of the SL-103, based on the technologies of the renowned MP-L201.
All Vitus Audio line stages contain a full bypass feature. This allows external surround processors to take full control of the volume when used in a multichannel system.
The SL-103 Line Stage is a true balanced design. This extreme unit offers 2 unbalanced and 3 balanced inputs and outputs.
When Used in conjunction with a pair of SM-011 monaural power amplifiers, the SL-103 is a genuine world-class preamplifier and one which utterly transforms the way you listen to music.
The size of the soundstage and the scale of the sound is huge, with life-like dynamics which will get you closer to a live musical performance than ever before.
It has incredible tonal balance with vocal accuracy so palpable you’ll question everything you’ve ever heard previously.
