A pair of enormous and expensive Holophone speakers, weighing something like 70 kg each, with a WAF close to zero and an utterly dreadful sound by todays standards. The worst thing is that I will move to a new flat soon - I am mentally almost prepared to leave them for the next tenant, even for free.
Having owned and listened to such objects was still kind of useful, because I learned many things in the process - first of all to think a little before buying something. And also that small speakers, which can be had for a fraction of the price of these monsters, can well sound much much better.
