Stereo Preamplifier Reviews

While the industry and enthusiasts alike may be moving towards multi-channel audio and home theater there is still a huge market for quality two channel (stereo) preamplifiers among audiophiles and home theater enthusiasts alike. While today's modern stereo preamplifier may not have all the bells and whistles of their AV processor counterparts they're hardly out of touch, with many possessing features such as iPod connectivity, built-in DACs, Bluetooth capability, subwoofer outs, home theater passthrough and, in some rare occasions, even HDMI video support. Sure they may not decode Dolby TrueHD or DTS Master Audio but if you're looking to get the most out of your extensive LP, CD and even digital music collection, a dedicated stereo preamp is still the best way to go.

1.0 What is an Audiophile Stereo Preamp?
A stereo preamp is an audio component that receives and switches audio sources, usually in the analog domain, as the listener sees fit. An audio preamp also boosts the line level signal from a source component like an iPod or CD player to a level that a power amplifier can use to power speakers.

The idea of a separate amp and preamp became popular in the 1970s among audiophiles for performance (and vanity) reasons. The idea that each component would have its own power supply was common wisdom as to why a consumer should upgrade from a receiver. Audiophiles loved the idea of mixing and matching components to create different sonic flavors in their systems.

An integrated amplifier is a component with a stereo preamp and power amp in one chassis. The main difference between an integrated amp and a receiver is the lack of some sort of tuner.

The AV preamp, derived for the home theater and surround sound from the stereo preamp, has most of the features of an AV receiver without power amplification of any kind.

2.0 Types of Stereo Preamps

2.1 Solid State preamps
The solid state stereo preamp is the most common variety, using transistors mainly to boost the signal from line level to a voltage that a power amplifier likes. The solid state stereo preamp was the first to come to market with remote controls.

2.2 Tube Preamps
Another popular variety of stereo preamp is the tube preamp, which can use various levels of vacuum tubes to boost gain in an audio system. Most tube preamps today also come with remote control. A Tube preamp requires replacing the vacuum tubes periodically or the performance will suffer greatly. A solid state preamp is a more "set it and forget it" component, which some consumers like better.

2.3 Digital Preamps (with DACs)
A relatively new category of preamp is the digital preamp, which unlike tube preamps and solid state preamps can accept a digital audio signal from products like an iPod or a CD transport. The internal digital to analog converter converts the digital signal to analog and it is boosted from there for use by the power amp.
