Simplified amplifier providing sharing of music with enhanced spatial presence through multiple headphone jacks

A device for enhancing a multi-channel signal from a personal listening device comprising:

• A) means for routing a multi-channel input signal from outside the case of the device to internal circuitry of the device, the multi-channel input signal is a stereo signal, the means for routing an input signal to the internal circuitry is an input jack, and the output connectors are headphone jacks;
• B) internal circuitry including means for providing a cross-feed signal between at least two channels of the multi-channel signal with the signal of the cross-feed being a function of the signal for another channel, the internal circuitry utilizes fixed resistors for determining the ratio of cross-feed between the stereo channels with the values of the resistors such that the percentage of cross-feed from each channel to another is between three and ten percent of the input signal;
• and
• C) means for routing a multi-channel output signal from the internal circuitry of the device to a plurality of output connectors such that provision is made for more than one listener to listen to the multi-channel signal.
