There are two basic types of electronic circuit topographies utilized for analog signal processing; solid-state (transistorized) and vacuum tube. The debate over which style sounds better will go on forever, but what it boils down to is taste and practicality. Each design offers something special or unique. Vacuum tube preamplifiers sound punchy, warm, yet wonderfully airy and transparent. Vacuum tube circuitry is also renowned for its ability to bring digital recordings to life. On the other hand, vacuum tube preamplifiers are generally not as quiet as solid-state preamps, because electron emissions from tubes tend to convey more "thermal" noise than transistors do. Vacuum tube preamplifiers require a bit more maintenance and are less practical for remote recording. In addition they produce heat that must be adequately vented. Solid-state preamplifiers tend to sound very clean (some say clinical) and offer the least coloration to the signal. They usually run cooler, travel better, and require less maintenance. You can expect less "personality" from a solid-state pre, which may be good or bad, depending on what you're looking for. It comes down to your preference, taste, budget, and need for convenience.
