Emotiva XPA-3 Three-Channel Power Amplifier

ARTICLE INDEX

Introduction

The term "separates" was once reserved for the upper crust of the home theater world. Only those with the most discerning ears (and fattest wallets) considered purchasing a separate preamp/processor and multi-channel power amplifier. That time has long gone, thanks in part to the rise of Internet-direct firms such as Emotiva.

Emotiva makes amplifiers--big powerful amplifiers--and sells them direct to customers at seriously low prices. Emotiva amps have such a high price/value that a SECRETS editor who is normally not prone to dramatic statement said that his Emotiva amps would "have to be pried out of my cold, dead fingers." He was talking about the top-of-the-line XPA-1 monoblock amplifier.

Emotiva's XPA line also includes a two-channel and five-channel amplifier, and the subject of this review, the $699 XPA-3--as in three channels. I understand why someone would want a five channel amp for home theater, and a two-channel amp for stereo, but what is the purpose of a three-channel amplifier? Let's find out.
