　　The S-300i is a smooth operator from a company that knows the territory. Its functions and configurability illustrate Krells crossover expertise in home cinema and the high end. Fit and finish are stunning-. Wholly designed in Orange, CT, and built in China to Krells specifications, the casework is seamless; edges and trim are smoothly rounded. Borrowing some of its styling cues and ergonomics from the S-1000 controller, the richly polished aluminum front panel houses buttons with hermetically sealed push-button switches that engage with a reassuring click. The machined aluminum volume/navigation wheel generates just the right amount of feedback to the hand. It also accesses the S-300is control menus, which can be viewed on the units front-panel display. The menu system controls such functions as balance, input trim, input naming, and muting level. Krell also gets the adjustably illuminated display just right-readable by human beings, not eagles. The rear panel includes three RCA line-level inputs, a balanced XLR input, and an iPod/iPhone interface (a cable is supplied) that taps audio from the fully differential output. Unfortunately the interface does not export the iPods metadata to the front-panel displayan oversight in my view. Naturally theres a theater pass-through mode. External control systems such as AMX and Crestron touchscreens havent been forgotten eitherthe S-300i provides 3.5mm jacks for IR input and 12-volt trigger input and output, as well as an RS232 connector. High-quality speaker cable terminals complete this well-equipped package. A full-function remote is provided.
