Really,…you have to have it! If ever, loudspeaker position/placement is important.
I have this CD for some time already…
Only of late that I realised how useful it is. I used to spun my favourite Music CDs of multiple genre to fine tune the loudspeakers placement…which I still do. However, the ISOTEK / OPUS CD allow me to confirm the position(ing) of the loudspeakers for (especially) soundstaging and spatial effect…that usually involve spinning a number of tracks from a number of music CDs.
Try it and…enjoy
