Why do some amplifiers throw a bigger soundstage than others?


Was watching a YouTube video comparing two Excellent class A amplifiers . the reviewer preferred, the one which threw a wider soundstage with the same set of speakers. Specified channel separation in db iis about the same in all quality amplifiers., so why does this happen?

IMHO, clarity is one of the most significant contributors to soundstage. If your speakers have good phase coherency, and are mated with an amp with good clarity, you should get a good soundstage if properly setup.

 

Why do tube amps generally have larger sound stages? maybe its a harmonic effect some amp do them well some don't.  Is it distortion effects, even/odd order effects?

clarity maybe, but I've heard some older vintage tube gear throw a huge sound stage with out great detail and clarity levels. so really doesn't hold up in my experience. 

Even though the OP used a YouTube video as an example its still a valid question that many of us have experienced when trying new gear.

@rrm Two things: lack of phase shift and aural effects having to do with the 2nd and 3rd harmonics, the latter of which can make an amp seem more detailed and spacious.
