The S-550i is the larger of two new integrated amps from Krell. Both of these amps feature circuit boards that utilize surface-mount components. This means they can pack more power into smaller chassis than ever before. The S-550i is rated at 275 watts per channel into 8 ohms, and that doubles to 550 wpc into a 4-ohm load. This is all from a box that is less than 6 inches tall. So now you can get tons of Krell goodness in a small package and at a very affordable price. For the uninitiated, Krell has been around for almost 30 years now, producing fine-sounding equipment with a rugged, industrial look. Some of the all-time best systems I have ever heard were built around Krell amplification and digital source components. The S-550i embodies many of Krell's famous design features from its past amplifiers. Let's first begin by taking a look at the preamp stage. The preamp circuit is pure Class A biased and fully balanced. The architecture of this circuit is Krell's proprietary Current Mode topology, which is a very high-bandwidth design: Krell rates the preamp section as flat to 1 MHz!
