With a completely no-compromise design, the SM-103 Mk.II can take on the very finest products from around the world, regardless of their cost. Based on the SS-103, each SM-103 Mk.II uses only the finest matched transistors and super precision resistors to ensure optimal working conditions for the different stages of each module.
Signature Series

SM-011
These incredible pure class A/AB mono amps share a chassis size with it’s sibling the SS-025 Mk.II. Based on the technical leaps made with the original SIA-025, the SM-011 uses SMD in place of leaded components wherever possible, fitting an incredible amount of technology in a modest space.

SS-103
Developed alongside the SM-103, this stereo power amplifier offers performance comparable to its monaural sibling in a single chassis. Quite simply, this amplifier is focused on musicality to thrill your senses.
With a dramatically lowered noise floor, the resolution offered to the listener is nothing short of breathtaking. And because it’s based on our modular design, this amplifier is upgradable making it a future proof investment.

SS-025
The SS-025 is a stereo power amplifier designed to fundamentally improve your audio set up taking your listening experience to the next level. Packing huge power inside a relatively small chassis was no easy task, but our engineering team have once again pushed design to the very limits to create a power amp that will astound with power, clarity, performance and musicality.

SL-103
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.
