The equilateral triangle should be considered a guide or a starting point. What works for some users in some rooms with some speakers may or may not work for you. The experimental process should be fun and not a chore. When you discover a placement you like, mark it with tape on the floor or document the dimensions and see if you can make any further improvements from small adjustments. If not, go back to your preferred positioning. The stereo image coming from your amp between the speakers is actually what you are striving for. If this bothers you, move the amp as you said or even better listen in the dark.
Making speakers “disappear”…..
So I’m just setting up my new system and dial it in-
Benchmark AHB2
Benxhmark DAC 3
Totem1 speakers
all trial and error here but…..when you guys are dialing in speaker placement do you move them around, closer and further away until the sound doesn’t actually seem that it’s coming from the speakers? So far I’ve found that sitting in a “triangle” - equal distance from the listening position that the speakers are placed apart and so far so good - do you guys do this or have any tips for me on this?
