One of a nice handfull of $500ish planar magnetic headphones at the show, I was impressed with the Advanced Alpha at CanJam@RMAF last October. In my report I said:

Maybe it was just the show conditions, or maybe I was just in the right mood, but holy smoke these sounded really good to me on first listen. I've been wrong at shows before so don't take this as gospel, but I sure liked these Advanced planar magnetic cans.

Well, time to find out if we can trust my ears at shows.

The XA25 stereo amplifier is the latest addition to Pass Laboratories' XA series of amplifiers and, at $4900, the lowest priced. It weighs only 45 lbs, has single-ended inputs only, and outputs 25Wpc into 8 ohms, 50Wpc into 4 ohms, or 100Wpc (!) into 2 ohms. According the XA25's well-written owner's manual, it will deliver 50W peaks into 2, 4, or 8 ohms—in class-A.
