In fairness we were given a free hand with the test discs.  In fact Acoustica were excellent in this respect, they just left us in a demo room and swapped the speakers for us.  The room was uncluttered except for some room correction items, this is the best Ive seen at a dealer.  We concentrated on Led Zep, we both know there recording very well and some of the early stuff leaves alot to be desired, CD quality wise.  Looking back I think the 803's might get a further demo but not the others. 

BTW Ju, we've not has an S5 update for a while, hows the beasts doing??
