    Default Pass Labs X350.5 Stereo Power Amplifier Review

    The Pass Labs X350.5 is a big, heavy, power-hungry amplifier. Itís difficult to transport requiring either one herculean mover or two normal people to set it in place. Because of its high bias into class A operation, itís also very power-hungry. I measured a steady state power consumption of 500 watts with the amp just sitting there in idle. Pass Labs specifies a 600 watt idle power consumption which is likely based on long term operation after the amp is fully warmed up.

    The X350.5 runs very hot so be sure to give it plenty of ventilation. Green activists wonít be too keen on that and quite frankly I wish Pass Labs would offer the option to lower the bias current for more power conscious audiophiles. This is the type of amplifier Iíd recommend for critical two-channel installations as it would prove too costly and too energy demanding to setup a full multi-channel system employing several of these units. A top shelf component like this deserves the very best accompanying equipment to show off its true potential. Make sure you have worthy speakers, good room acoustics and a solid preamp capable of at least 3Vrms unclipped drive output with a very low noise floor.

    Jeebus, looks like a beast. Think I will pass at the price though. I wouldn't pay no more than 9k for it. lol
