to be honest this technology goes way over my head but,many years ago i went to olympia (a big exhibition in london) to look at the latest hi fi equipment,all the makers were there but one stand i went to ,the sound was UNBELIEVABLE it sounded like a large band,which most of us thought was hidden behind a curtain,a few of us even said so,the man in charge went to the back and pulled the curtain open,NOTHING, then he showed us this box,he took off the lid and all we saw was a system full of valves,its a pity i can,t remember the name of it,all i remember is that it was really expensive but sound wise superb,grahamuk you was in the trade i wonder if you know?it sure it wasn,t QUAD,mike
