This stunningly beautiful player had a maximum output of 2.7V, which is both higher than the 2.4V specified and higher than the CD standard's 2V RMS. The output impedance was a low 57 ohms across the audioband, and the player inverts absolute polarity.

The Oracle's frequency response, with (top) and without (bottom) pre-emphasized data, is shown in fig.1. With a regular signal, the response is perfectly flat. With a pre-emphasized signal, however, a large (-1dB) error appears throughout the treble, which will be audible (on those few discs that have been…

To date, nothing we had found seemed to suggest that this system was worth anywhere near the $1140 the…

KLH Nine: Low efficiency, highly reactive loading characteristic, and superb transient response make this speaker extremely critical of the driving amplifier and input signal cleanness; drivers well-blended; tweeter highly directional, best heard off-axis; sound very smooth, liquidly transparent, likened to a spotlessly clear window on the sound; "Row-M" perspective places sound rather behind panels; somewhat cold sound; two panels (one complete Nine system) essentially flat to around 40Hz with panels together, gradually rolled-…

Manufacturer: KLH Research & Development Corp, Cambridge, MA (1966).

Say you own your own home. Let's also imagine that you've built a pretty decent listening room. How's the bass? Does it seem to "leak" out of the room when you crank the system? Adding subwoofers won't help a room that leaks bass through flabby walls. On the other hand, a concrete bunker isn't ideal either. That kind of room…
