Widescreen Review

The SP4 processor produced sound that is clearly the equal of other high-end processors. It definitely has the “chops” to match competitors for any evaluation parameter I could think of, from low noise floor, to a neutral sonic character that lacks any artificiality. There is: no harshness when reproducing massed stringed instruments; no over-emphasized sibilants; no glassy, gritty, dull, or harsh or mechanical-sounding treble sounds; and no loss of dimensional size in stereo or multi-channel sources, even at lower volume levels.
