I have had different models of Audio Physic speakers. They all produced a wide soundstage beyond the speaker boundaries. I have tried many positions in a few very different rooms. The speakers just disappeared in a very wide stage. Most were older models though, when the original designer Joaquin Gerhard was still with the company. (Designer spelling may be incorrect.)
Soundstage
I have a decent size room 20’x33’x9’. Due to the placement of some large columns I need to place my equipment on the long wall. While I can achieve an equilateral triangle between seat and speakers (11’ on all sides) .... I am unable to have the front of the speakers more than 3’ from the front wall. I am using Avantgarde Uno speakers with Pass Labs XA 60.8 amp and AR Ref 6 pre. Sources are Lumin X1 and SME 20. The overall sound and imaging are wonderful. There are two problems that I can’t seem to get right. First, the soundstage is rather narrow ... does extend beyond the speakers (have tried every off to on axis position). Second, the image is detailed/precise but not deep ... it just sort of hangs on the wall 3’ behind the face of the speakers. I believe that the problems are due the speakers not being far enough from the front wall but I can’t move them out more (due to the columns I mention). Any suggestions on how I might fix these two problems?
