Term of the Moment
cellular hotspot
Definition: stereo amplifier
A two-channel amplifier that requires a preamplifier. Such equipment ranges in price from under $100 to tens of thousands at the top end. Although a separate preamp and amp are often combined (see integrated amplifier), audiophiles with hefty budgets prefer an individual amplifier for each channel. The complete separation of left and right amplification ensures that there is no interference between signals. The cost is generally double that of a two-channel unit. See preamp.

A pair of these German-made Octave Jubilee Mono SE amplifiers are only $80,000; however, they are said to produce the most beautiful sound one can imagine. We surely hope that is the case. See mono block. (Image courtesy of OCTAVE Audio.)
