Convergence is a widely used buzzword in today's consumer-electronics industry. However, other than using my PC's soundcard in the office to play back MP3-encoded music and plugging the Mac in my listening room into my reference system in order to experience Riven with the highest possible sound quality, I've kept a low profile in this area.
Is Krell risking its reputation? With the KAV-300i, an integrated amplifier that was originally envisaged as an export model, but for which home demand is clearly increasing, the Connecticut-based amplifier manufacturer is dabbling in low-cost territory. Previous Krell amplifiers have been known for their prodigious drive capability. Time and time again, it is found that the true measure of the bass performance of a big speaker isn't realized until a Krell power amplifier is brought into service. But how could an amplifier with a meaty 150Wpc specification and full remote control be built to sell for just $2350.
As strongly as I believe that the listening experience is the most reliable method of judging the quality of audio equipment, I've been biased against single-ended tube amplifiers because of their quirky measured performances. Without having heard single-ended under good conditions—much less living with an SE amplifier—I had concluded that many listeners must like them because they're euphonically colored by large amounts of low-order distortion and impedance interactions with the loudspeakers. SE amplifiers seem to be a departure from the goal of making the electronics transparent. Moreover, the range of loudspeakers suitable for SE amplifiers is so restrictive that I wondered why anyone would bother with these underpowered distortion-generators. I had fallen into a trap that I've repeatedly railed against: drawing conclusions without firsthand listening experience (footnote 1).
