Headwear will aggravate this.

Have seen responses that NICAM is a companded audio system.  Same here.
dBX supplied part of the companding technology.
 NB> This is the case in the UK anyway, don't know if you have some 
 NB> equivalent where you are or not.
Yes.  Generally, it's very good.  However, pumping and video "trash"
have been known to add odd side-effects.
 NB> Was the dBX type 2 method the combination of Chrome and Metal tape or
 NB> something?
dBX type II is the consumer version for cassette/open reel
encode/decode units.  For the most part, it worked well, and unlike
Dolby, (B&C) it isn't level dependent for accurate decoding.  However,
a flat frequency response of the record/play chain is the main
requirement for good proformance.
 NB> Well believe it or not I have one and just wondered if anybody had

 NB> good, as long as your not looking for surround sound or anything fancy.
A good design, with quality componants will always sound fine as long
as those componants are in fine working order. :-)
 NB> Talking about surround sound has anyone here heard of the Hafler 
 NB> Surround method?
Yes.  However, Dolby Labs seems to be the dominant system, from what
I've seen.
