Naim SI Features
Decoupling and Isolation
Minimising mechanical, electromagnetic and thermal interference between components is a key part of Naim Audio design. Decoupling sockets to cut off interference from incoming mains power and suspending circuit boards on brass sub plates to create an isolated environment for critical electronics are two applications of this principle. A less obvious example is the creation of small bends in individual resistors by hand, decreasing microphonic interference (microscopic vibrations which degrade sound quality). But similar techniques are applied at every level of the design and build. And we only introduce techniques if they prove effective and repeatable in listening tests.
Hand-matched Componentry
Matching the characteristics of sound critical components for each channel (left and right speaker) of an amplifier can greatly improve sound quality. Batches of resistors typically come matched to within a 5% margin of error. Through listening tests we found that if the resistance of the left and right channels are matched to closer than 0.5% music becomes dramatically more communicative and engaging. Following this discovery a bespoke production procedure was conceived to help us match resistors by hand.
