Flying Mole Electronics is the whimsical name of a company that makes some compact, relatively inexpensive, and, from what I heard in their room, very good-sounding audio electronics. How compact? Well, just look at the picture of their CA-S3 integrated amp, with a CD box next to it for scale. The amplifier is described as "proprietary bi-phase PWM," with an output of 20Wpc, and sells for $850. The larger—but still compact—CA-S10 ($1500) puts out 100Wpc. Both are claimed to have a tube-like sound. The little CA-S3 did a good job driving both a custom system based on JBL components and a more conventional bookshelf-sized speaker from Von Schweikert.
