I was going through some QE2 material and came across several references to "Linn HiFi". Apparently in the mid-late nineties this company (it does still exist I checked it on Google), provided the audio-visual technology. But there was more, according to one of the ship notices Linn Hi-Fi had a demonstration shop situated on the upper deck by stairway E. Having looked at the company site it is very much up-market and high quality bespoke equipment, with the obvious price banding. I was therefore tickled with the programme strapline of "shipboard prices"
