You need lots of it to stay in control when speaker impedance fluctuates, and to hang on without clipping as the soundtrack suddenly explodes into action. We use a massive high-power transformer to drive discrete, low-negative- feedback amps that cut distortion and preserve the energy of music. Delivering 90 watts per channel, the TX-NR535 packs a colossal punch for movies but still retains the pure musicality you need for two-channel playback. Also, Phase-Matching Bass Enhancement optimizes low frequencies while preserving mid- range clarity. It counters phase shifting (which generally occurs in the zone occupied by vocals) by synchronizing the timing of different frequencies. The result is deep, well- defined bass that won't blur vocals or strings.Built-in Internet Radio and StreamingIf you can think of it, you'll most likely be able to stream it on your TX-NR535.
