Passion 600

About the Passion 600

The YBA Passion 600 power amplifier delivers approximately 150 watts per channel into 8 ohms and 300 watts into 4 ohms, with a conservative clipping point around 185 watts at 8 ohms and 385 watts at 4 ohms. It is highly regarded for its neutral sound with a slight warmth, purity, speed, and tight bass response. The amplifier is load stable down to below 1 ohm, making it suitable for demanding speaker loads. It runs cool and is designed with high-quality components including ON Semiconductor MJ15024G + MJ15025G bipolar transistors in TO-3 enclosures, a massive 1000VA Ul-core transformer, and high-precision low-noise resistors and polypropylene capacitors with vibration damping. The amplifier weighs about 25 kg and measures approximately 430 x 397 x 178 mm. It features two pairs of gold-plated speaker outputs, stereo RCA and balanced inputs, and a mono balanced input for bridged mono operation. The design includes eye-catching heatsinks shaped into the YBA logo and a power output meter on the front panel. The amplifier is praised for its musicality, natural transparency, and correct timbre, making it a favorite among audiophiles seeking both power and finesse.
