SL-103
Line Stage
Signature Series
The meticulous pursuit of the miraculous
It’s a recurring story at Vitus Audio: After much cautious and painstaking consideration, we will make a critical change to one product which then has unforeseen implications, enabling us to make significant improvements to other items in our range.
In 2010 we made some transformational improvements to our SL-101 line stage model, inspired by the fundamental innovations inherent in the design of the Masterpiece Series MP-P201. We increased the number of regulation levels in the power supply and added more volume steps to accommodate higher resolution in the attenuation.
A line stage with pedigree
The original SL-100 was launched at CES in January of 2004 and this lineage in the Signature Series has been a firm favourite with audiophiles ever since. This current iteration pairs perfectly with our SM-011 Monaural Power Amplifiers to create a system to satisfy the most demanding cravings for musicality and performance.
Finishing
The SL-103 comes in Pure White, Jet Black or Warm Silver as standard. Titanium Orange, Dark Champagne and Titanium Grey are our most popular unique finishes.
