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?

there are resonances occurring in the system that are causing an effect of reverberation. Examples include feedback

That seems plausible.

Back in the late ’90s a dealer let me take home a Mesa Baron for the weekend.

I was immediately intrigued and impressed by how up front and close the soundstage was (particularly the vocalist) and how it filled the room to an extent I had never experienced before. At the time I was running a Cary SLA 70 Signature (Cary’s entry level push pull amp) and the reason I did not buy the Mesa and stayed with the Cary (for the time being) was that the soundstage of the Mesa was not nearly as clean and defined as that of the Cary. As a matter of fact, the way I described the soundstage of the Mesa was as being "smoky."

Since then I have owned a couple of other amps (a pair of ARCs and a larger Cary) which provided a larger soundstage, but really nothing quite the same as what the Mesa did, and I have often wondered about that.

I did try to post a link for the Mesa, as I always thought it was a looker, but for some reason A’gon won’t let me do that.
