I would like to hear from anyone who has a recommendation or opinion on the use of time delay and/or ambience systems with stereo systems. A prototypical unit would be one sold by Koss and available through several discounters for approximately $250. I have also seen a unit made by Sony. 1) Do these systems enhance the feeling of realism? 2) What has your experience been with individual units? Thanks in advance.

I've been using the Advent SoundSpace control, which uses PCM and RAM storage for the delay effect. The unit is no longer in production, but a few outfits still make time delay systems, like the Koss. I haven't heard the Koss myself, but from what I understand, it could benefit from a better set of speakers than the ones supplied with the unit. I use a separate, 20-w/ch amplifier and a pair of EPI-100 speakers for the rear channels. As Advent recommended that the rear channels be driven at about -6dB below the primaries, this is pretty well matched to my 80-w/ch main unit. The effect you get varies considerably with the type of music you are listening to. It does a great deal to enhance the realism of live recordings and classical orchestral recordings, as well as some studio-produced stuff that ordinarily has an airy quality (e.g., Pink Floyd's "Dark Side of the Moon"). Most delay systems allow for user-variable reverberance and delay, so you can create many effects to suit your tastes. I find that I can no longer listen to music without it, as ordinary stereo sounds rather flat and lifeless without it. Unfortunately, a good delay system requires a substantial investment. I guess that's why they never caught on. -- Bob Fishell ihnp4!ihu1g!fish
