Here are some things not on the average audiophiles‘ radar I have found degrade the soundstage. it’s no wonder most systems, even very advanced ones, lack a big beautiful soundstage. By the way, none of these things below have anything to do with acoustic waves in the room or anything in the signal path anywhere in the system, with the exception of 3, open cell foam. This is not (rpt not) intended to be a complete list. Not by any means.
1. Any type of media in the room, including books and magazines, telephone books, LPQs, CDs, videos.
2. Too much wood, glass, metal in the room.
3. Open cell foam in the room, including SONEX room treatment and chairs, couches.
4. Cell phones and clocks and watches. Big no-no!
5. Spare/unused electronics, cables, cords, musical instruments, speakers.
6. Static electric charge on clothes, carpets, electric cords, windows, etc. degauss them pronto!
The big beautiful soundstage has been in your room the whole time, you just can’t hear it properly due to reasons 1-6.
Don‘t blame me, I didn’t create reality.
An ordinary man has no means of deliverance.
