I would think that class A amps with less negative feedback would have a bigger soundstage, that could be one of the reasons many tube amps have a great soundstage.
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?

@atmasphere I’d assumed that has more to do with a discrepancy between wavelengths and reflection time vs. boundary dimensions, than with how we perceive bass overall (granted, research indicates certain higher frequencies are disproportionately influential on our sense of spatial scale). Should spatial perception x what you describe differ for, say, bass in outdoor setups (I am sorry - I realize this is slightly tangential from the OP query)?
This made me chuckle at myself. Bass in my setup comes from stereo subs that can go up to ~180 Hz (I keep them crossed at 100 Hz). When I was setting them some years back, I did play them without the towers but directed my attention to measurements vs. room modes (vs. listening impressions); I admittedly wasn’t focused on soundstage of given tracks. “Tell me you already knew something but didn’t know how to say it ‘til just now.” I’ll aim to give that simple experiment a whirl this weekend if time permits. Thanks again. |
