I agree with everyone that has mentioned Spica speakers. But nobody has mentioned the best Spica speaker. The designer himself said he liked the TC-60's the best. I have to agree with him. These speakers in a large room throw an unbelievably large soundstage.
Which speakers do the hologram thing?
Some reviewers talk about how speakers can produce a 3-D image so convincing that it seems one can "walk amongst the performers" or "sense the air between performers," or they may say how "each musician appears to occupy a solid space," etc. I'm not certain I have heard this. In your experience which spekers have this ability?
