Defining noise is tricky business.

In high-end audio, noise is often defined as the enemy—of music, beauty, truth. Engineers and enthusiasts alike spend significant amounts of time, energy, and money attempting to minimize or control noise so that it has the least possible impact on the source signal: music. In this way—if we are intelligent, careful, and fortunate—we can extract from our stereos cleaner, clearer, more naturally beautiful sound for listening experiences that are enriching, emotionally compelling, and, above all, fun. On the other hand, when noise is allowed to excessively modulate the signal, music can sound relatively abrasive, more mechanical, and, ultimately, less engaging.

Conductor Osmo Vänskä, whose Minnesota Orchestra has previously distinguished itself in multiple recordings of Sibelius and Beethoven, is now turning to the symphonies of Gustav Mahler. Newly arrived is his hybrid SACD, for BIS, of Mahler's Symphony 5. The first issue in a projected series that will next offer Mahler's Sixth and Second Symphonies at dates unspecified, it may not win over those whose allegiance adamantly rests with Bernstein, Chailly, Rattle, Abbado, Tilson-Thomas, Fischer, and/or other distinguished Mahler interpreters. Nonetheless, the strength of the recording's first movement alone, and its hi-rez provenance as DSD derived from 24/96 file, make its epic journey from darkness to light essential listening.

Palmer Audio's 2.5 turntable, with its laminated plinth of Baltic birch and metallic features, looks Scandinavian but is made in the UK. It shares a few conceptual similarities with the turntables made by Nottingham Analogue, another British brand. The review sample had the optional side panels of cherrywood veneer.
