Fed the right diet of cables interconnects, speaker cables and power cords , the XA exceeded my expectations. Careless cable or component matching quickly reversed those findings and had me judging this fine amplifier unfairly.
Pass Labs X and XA amplifiers are gorgeous components. Apply whatever slang term you choose -- eye candy or audio jewelry -- the Pass XA is aesthetically pleasing.
The XA is physically imposing. Tall, deep, and heavy, it stands 19"W x 11"H x 22"D and weighs pounds. I suggest you solicit a little help from your friends when you uncrate and install these amps. As you have likely gathered, the Pass XA is not of this compact genre but is a classic beefy, analog, class-A amplifier with a gargantuan transformer and the huge heatsinks necessary to dissipate the enormous amount of heat generated by W of pure class-A power.
However, anyone with 2- or 4-ohm speaker loads hoping to get the XA to double down into decreasing impedances need not apply. A small switch on the rear panel places the amp in standby mode, and the round button in the middle of the faceplate illuminates the blue meter and brings the amp to full power.
My experience was that, after initial burn-in, the XA needed at least 45 minutes to settle in and sound its best. I began my listening with the toughest speakers in my collection, the Magnepan 1. The more powerful, heavier, A only stayed in my system briefly, but the A stayed for quite some time and was always a favorite. To get them to softly clip requires ear shattering volume, or perhaps a pair of horribly inefficient speakers.
In that case, there are always the XA No matter what music is served, the XA However, this additional richness and palpability is not at the expense of softness, or compromise in transient attack.

Does the fact that the amp is so well designed to be immune to vagaries in the power supply negate the need for superior power cabling? Not at all! I had a discussion in an online forum in which an electrical engineer stated that an amplifier such as a Pass is unaffected by power cable swapping —- in fact, he used this very amp as his example!
As the XA If that is what a better amp does, I want no part of it! Maybe Nelson is not laughing now. No matter, as he is a gregarious and generous guy, able to accept that the audiophile tent is large enough for individuals with disparate viewpoints. I do not worship at the feet of any designer; I use their gear and report what I hear. I hear distinct differences in presentation when swapping power cords with the XA The real test for me is listening, and once again my suspicions were confirmed.
The Pass XA This should not be surprising. It also was not surprising that the Wireworld Silver Electra power cord was cooler and more tipped-up in sound with the XA This outcome is in line with every previous use of these cables.
