Obviously, the more money you invest, the better the performance and sound quality of the preamp you buy will be. Signal-to-noise ratio is the most important criteria; the higher the number, the lower the backround hiss level will be. This may not be particularly crucial if the overall playback system\'s quality is low (a cheap minisystem or sound card, for instance; both may generate enough hiss in their own right to obscure any added by the preamp), but matters a great deal when comparing LP fidelity to other sources like CD on a good playback system. Ability to faithfully correct RIAA equalization is another important sonic quality; higher-priced products do it better. Additional features like mike inputs and a power indicator may be useful to one user but not to the next; buy only what you need. |
