I apologize for any confusion. I have a 2ch stereo system & an A/V surround system in same room. They are independent of each other. The 2 Holos are simply sitting on top of the rear surround speakers. The top of those speakers are a convenient & effective location for them.
As for swimming vs your term "drowning" in music, swimming really is an apt description. However, if a particular piece of music sounds more natural playing in a narrower, more authoritative & slightly forward soundstage, you can experiment with different locations to achieve your goal.
For example, moving the 2 Holos from the front corners of the room to the tops of your main speakers will narrow the field while still retaining a good deal of the immersive effect.
My point is they are unobtrusive & easy to relocate depending on your desired outcome. Start with a set of 4. They are very powerful! At the moment, I have placed 1 Holo on top of both front speakers, 1 Holo on top of both rear surround speakers that are part of a separate A/V system because they surrounds were a convenient location, 1 Holo on top of each binding post on back of the front speakers. 1 Holo ear level in the middle of both side walls. You can literally tune your room with Holostages.
Rich, dense, saturated, resolving imagery!
Finally, you owe it to yourself to give these little black boxes a try.
